Another Solar System Like our Own?

There is another Sun-like star out there with an intriguing family of planets orbiting about and it could be the closest parallel to our own solar system that astronomers have found yet. European astronomers discovered a planetary system containing at least five planets, orbiting the star HD 10180, with evidence that two other planets may be present. If confirmed, one of those would have the lowest mass ever found.

“We have found what is most likely the system with the most planets yet discovered,” says Christophe Lovis, who led the team. “This remarkable discovery also highlights the fact that we are now entering a new era in exoplanet research: the study of complex planetary systems and not just of individual planets. Studies of planetary motions in the new system reveal complex gravitational interactions between the planets and give us insights into the long-term evolution of the system.”

To make this system even more intriguing, the team also found evidence that the distances of the planets from their star follow a regular pattern, as also seen in our Solar System. “This could be a signature of the formation process of these planetary systems,” said team member Michel Mayor.

HD 10180, is located 127 light years away in the southern constellation of Hydrus. The five confirmed planets are large, about the size of Neptune — between 13 and 25 Earth masses —with orbital periods ranging from between six and 600 days. The planets’ distances from the star ranges from 0.06 and 1.4 times the Earth–Sun distance.

“We also have good reasons to believe that two other planets are present,” said Lovis. One would be a Saturn-like planet (with a minimum mass of 65 Earth masses) orbiting in 2200 days. The other would be the least massive exoplanet ever discovered, with a mass of about 1.4 times that of the Earth. It is very close to its host star, at just 2 percent of the Earth–Sun distance. One “year” on this planet would last only 1.18 Earth-days.“

This object causes a wobble of its star of only about 3 km/hour— slower than walking speed — and this motion is very hard to measure,” says team member Damien Ségransan. If confirmed, this object would be another example of a hot rocky planet, similar to Corot-7b.

The newly discovered system of planets around HD 10180 is unique in several respects. First of all, with at least five Neptune-like planets lying within a distance equivalent to the orbit of Mars, this system is more populated than our Solar System in its inner region, and has many more massive planets there. Furthermore, the system probably has no Jupiter-like gas giant. In addition, all the planets seem to have almost circular orbits.

With this new announcement, the total number of exoplanets found is 472.

    • 127 light years is just next door. our closest neighbor is a 3 star group just over 4 light years but due to the complex orbits of the 3 suns there wouldn't be any planets, they would just get pitched out. one day the problem of distance will be solved and we might find out what this existence means. now i have a craving to watch old "enterprise" episodes,

    • everytime i think of external life i remember the scene from avatar where he first syncs up with the body and runs out of the hospital thingy, point of the comment is he eats a juicy...fruit...i want to take a bite of that...i wonder what other cool things other planets have to offer..

      You're funny, but I like dreamers. Those lights yur looking at, they aren't street lamps. They're stars. If it was a trillion street lamps all turned on you'd have a good argument. Get it... Got it. Good.

    • The way to reach this new solar system in an instant of time requires first the craft achieves Light Speed (or close) and then #2 an artificial Black Hole has to be created in front of the spaceship. The gravitational pull on the craft rips a hole in space-time and you are there, at your new home.

      If you push the Black Hole button too soon ~ahead of reaching Light Speed~ you and your craft will be what gets ripped.

      I think it was more along the lines of having to retire our current ships and it being too expensive right now to send people up. Funding for space isn't completely cut right now, but what is more important? Finding funding for the education of our youth, or shoving it into a space program?

    • Colonize! This is the perfect solution to our population problem, colonize and we can ship back all the natural resources. I say that the entire evangelical church should go, ever last member and sympathizer. Ya know to really show our power as christians and as Americans. Just umm could we make one tinsy request, make it a one way trip.

      Queue to robot miner team! They won't care it takes them 25,000-500,000-1,000,000 years to get there, but if they figure out we'll be dead & gone by the time the refreshments arrive I imagine they'll go rogue, go sentient, and go deserters!

    • Thats nice I wonder what kind of critters live on that Planet that think human flesh taste like chicken? Better yet what kind of viruses that want to make our water or bodies their new home. No way is there a place like this one out there.

    • i love this...

      the thing is tho..if we find any more planets, you kno that will result in? planetary exploration, then people claiming planets (this is my planet, u do not belong), ppl ruling planets, then demolition of planets not understood. lol-yea..

    • Very interesting, if we can see another system like ours then just try to think how many others like ours there must be out there. Crazy.

      I'm conservative and I think a free thinking, understanding liberal such as yourself would make a much more effective ambassador for the human race. You know us, conservatives we get all uptight and aggressive when we come across a new culture that we don't understand. I think Liberals such as yourself should go there first set up a nice friendly relationship with the new alien culture and report back to us all there military secrets. Their tactical strengths and weaknesses, then we can come and do what us, conservatives do best......... INVADE AND DESTROY.......

    • Hello, parallell worlds...there are those who can travel far faster than the speed of light...they transcend our limited mentalities by millions of light years...

      When will mankind grasp the true potential of his ability to tap into the conduit of universal knowledge...instead of always relying on what he can see through a microscope or a telescope...it is his minds eye he should be looking through...to begin using that thing we call a brain...hence, the evolution of man...soaring to new heights...communicating with our more advanced counterparts out in the geat beyond and within the different dimensions that surround us here in our own atmosphere...our own little baby-talk world...

    • Driven like bleating sheep forced to be space explorers by destroying their cozy warm home planet. Destroying this planet to force the sheep to love being taxed for new propulsion {ugh} rockets.

      Those elite are a right smart bunch of shepherds.

      Just burn the grass to make the sheep find another pasture.

      And to make it even more fun to watch keep the UFO tech hidden.

    • I love this conversation. It is beginning to become obvious that earth type planets are near our solo system. But if we were to go to the stars soon, we would probably only choose three to start. Three chances bring the odds of success into the reasonable range.
      The simplest design would be a hollowed our asteroid from the asteroid belt, solid iron or lead would be best for cosmic radiation. Then hollow that rock out and build habitation, life support, other needed technology like landers, farming near the low gravity center during artificial gravity created by spin, some kind of engine drive etc.
      Most of the people would be the Sleeper Tribe, in some sort of suspended animation, probably based on cold living chemistry like from Antarctic insects.
      The Traveler Tribe would run the place for generations, maybe hundreds of years. Upon arrival at the new world the Traveler Tribe would research the planets biology in order to assure inoculation against disease. Some years later the Sleeper Tribe would be awakened and they would all set up camp on a new world.
      There is a less then happy scenario. If after arrival at the new world we find it is impossible to inoculate people against planetary disease, we could eradiate the planet with quickly dispersing radiation, like ex-rays, kill the entire echo system and move in our own ecosystem after the big rot is over. OUCH! But it’s in the realm of reality.

      There are millions of stars out there that replicate this solar system. We are not the only ones alive.

      Until we stop pitting the wealthy and everyone else against each other, we will never get off this planet. Uncontrolled capitalism is an anachronism in a world with limited resources. It is time to tame the capitalist beast so he serves all of us. Like China!
      Yes, it is obvious that China has abuses by the wealthy against the people. But they also have a crowd control problem. In the US when 5000 protesters come out to play, 15000 Chinese come out. That logistical problem can quickly be amplified if the US crowd is 1 million. So China controls it’s wildly successful capitalist economy in order to stop unrest from spinning out of control.
      We have a great opportunity to adapt a similar economic philosophy of controls on a smaller more manageable level, before things get worse. And far from using Chinese Communism as a governmental system, we can do it through our own Democracy. Socialism is a slave to Democracy that can be worked to raise all our economic levels, even sustained eco friendly economic jobs.
      Then we can get to the stars.

      Maybe...but we already did the capitalism versus communism thing in space exploration when the Soviet Union was alive and...well, alive anyway. The Soviets did a few things well but their program was by and large a disaster. Our capitalist society did significantly better in no small part because our tax revenues from those capitalist ventures and the income tax on those they employed yielded many multiples of the rubles that the Soviets could throw at the problem. Personally, I think we have to find a way to make space sexy again. But I worry that an increasingly large portion of our population lacks either the intelligence or the imagination to see the benefits of space exploration -- if for no other reason than to keep the species alive a bit longer if we continue to destroy our home (I was going to say "shit where we eat," but of course that would be crude ; )

      I've got it! We need to pay off china until we're even, then we make some sort of amazing spacecraft or satellite and then brag about it to the Chinese something like "Hey China check out our new spaceship, it can land and take off from the moon over and over again. Yea it's pretty awesome, you guys have something like that right? No? well we're going to the moon again so we'll see you later." Boom space race is on again.

      "Our" new spaceship? You mean the one "we" have but nobody rides in it but young astronauts because we don't qualify to ride in "our" own spaceship "our" tax dollars paid to design and build? That spaceship?

      What's your brag, Chinaman?

      it could one day happen, though i doubt it would be an international venture into the stars. we've squabbled over things as meaningless as power, borders, religions, resources, right down to pure psychotic rage since man has realized the killing power of spear and stone. we'll never stop. there are theories that we might even drag our violence into the vacuum of space, as we will continue grow more advanced, we'll still fight amongst ourselves without end. it's sad really... 40 years since we've been to the moon, and we still havn't gone back. why? because there's no resources to exploit up there. say they find massive deposits of valuable materials? we'd have a base on the moon in no time.

      "Socialism is a slave to Democracy that can be worked to raise all our economic levels, even sustained eco friendly economic jobs. Then we can get to the stars."

      We could get to the stars now if there wasn't a glaring lack of technology. Flying through space in a hollowed out asteroid is a dumb idea; everyone would undoubtedly die. And it wouldn't be hundreds of years, think more along the lines of tens of thousands. No agency is ever going to invest in a plan like that. We need something that can get us there fast, or else its just not going to happen. That's why these conversations about traveling to the starts are based in fantasy; we simply can't do it.

      we are a very egotistical species..also, the man made image of what 'God' or 'gods' are is the sole reason we see ourselves as the center of everything because we created an entity that tells us we were made in his image and that we're special.
      i can only hope that the next step in our evolution as a species will happen sooner than later and we can finally let go of all these archaic mindsets and live with an open mind that is loving and non-judgmental (un-biased).

      or that we will find a planet bearing life...that at least, will put my mind to rest.

      What makes people think that?
      Religion does.

      The Bible makes it clear that the Earth is a flat disc, the sun and moon orbit across it, and the Earth is covered with a metal dome called the "firmament", with all the tiny little stars suspended from it.

      And right above the firmament, right on the top surface, sits God on his throne, with all of the angels.

      Good point, but if we were the first and the sin in Eden was the first wrench to hit the fan then until the questions raised regarding God's Sovereignty are settled here the rest of those other worlds out there are waiting on us to either solve it or die.

      Now since if it had happened elsewhere first ~where Satan threw the wrench inta the fan there~, then we wouldn't be fighting the same battle again here because the Sovereignty question would have already been resolved and buried once for all Time there, but since we are it looks like Biblically yep, we are the first, the one and only.

      The first to live & wow right on the money the first to sin too. Which means we are the only ones to have to live or die at an "Armageddon". It all ends soon, both for us and for the universe to come.

      Is it just that, or is it lack of understanding. I mean yes, egotism is certainly part of it. Especially religious egotism. But what if it is also like Native Americans seeing European ships for the first time. I remember reading that the Nat. Americans' originally believed the sails to be some sort of cloud, and their minds didn't really "see" the rest of the ship that far out in the horizon because they not only had never seen a ship like that, but at their tactile level, could never comprehend making one. It wasn't until the ships were much closer did they realize it was a vessle of some kind. Also kind of like how it takes babies a while to comprehend shapes and images, or how a deaf person who has regained hearing can't comprehend certain sounds, right away. Takes time and experience to comprehend certain things.
