Discovery at the edge of the Solar System

"The Oort Cloud is a spherical cloud of comets believed to lie roughly 50,000 AU, or nearly a light-year from the Sun, which places the cloud at nearly a quarter of the distance to Proxima Centauri, the nearest star to the Sun. The Kuiper belt and scattered disc, the other two known reservoirs of trans-Neptunian objects, are less than one thousandth the Oort cloud's distance. The outer extent of the Oort cloud defines the boundary of our Solar System..."

    • 4to8ea.masses 4 billion milesaway planet x shold have been seen in mankinds remote past about 2012 well iwill be60 something and ret. if we get hit by nirubu i will have lived along and interesting life but..if the planetoid is fragmented i hope the anti=christ living in tehran gets smacked first as he certainly deservs it thinking some 12th madi is going to climb out of some well and bring ridiculous ialamic law into the rest of the world.on 2nd thought i will vac. in tehran and whack him myself as one last respite for mankind.

    • That was too much science for one website article.

      But besides that, I think this is amazing and we will continue to be amazed by what we find in our solar system. Just wait till we find the pearly gates. That'll really be something to get happy over!

    • The cometary membrane of the Oort Cloud and Kupier Belt actively feeds water to the interior planets, with some 20 to 40 ton water-ice comets hitting the earth's atmosphere 5 to 30 times per minute. Simulations show that Kuiper belt comets simply don't fall directly toward Earth's neighborhood but plod their way toward the inner solar system in stairstep fashion. It turns out that the massive outer planets are almost exactly spaced so that they "hand-off" comets from one to the other. At each step the powerful gravitational field of Neptune, Uranus, Saturn and Jupiter might either eject the comet from the solar system or pass it onto the next planet inside their orbit.

      This is the most exciting part of the article....

    • Comets have seeded the earth with water and life and have most likely at other times done the same for the other planets in our solar system. We are in a galactic nursery.

    • I love that their is something that big relatively close to us and we are just finding out about it. Its stuff like this that makes me realize how long things have been going on without us! Trippy.

      "The new object is much smaller than Sedna, Becker said, probably 30-60 miles across instead of nearly 1,000. "It's basically a comet, but it never gets close enough to the Sun to develop a long, bright tail of evaporated gas and dust."

    • The Oort Cloud isn't the new discovery here, it's been know about for many many years. The real discovery (buried 4 paragraphs into the source article!) is a new planetoid in the Oort cloud - a Pluto-sized object.

      Source article = journalistic FAIL.

      Scratch that, it's not even Pluto sized:

      Yes, in science-speak, this object has mass... but in the scope of the solar system this thing is TINY!

    • so, is our sun the hot core nucleus of the Oort cloud?
      it sounds as if the Oort cloud is like the membrane of our solar system.

      but the title of the article is confusing me: the scoop is 2006 SQ372, not the Oort cloud. it sounds as if they already know a significant amount about the Oort cloud. It's the tiny planet they decided to name "2006 SQ372" that they've discovered.

    • and whats up with all the Latin titles?, the solar system is one big Latin Fest , I'm not to enthusiastic about the titles. Proxima Centauri? BullShi.....I name it AMINA which is the name of an African Queen-

      QUEEN Of ZARIA (1588-1589)
      This queen of Zazzua, a province of Nigeria now known as Zaria, was born around 1533 during the reign of Sarkin (king) Zazzau Nohir. She was probably his granddaughter. Zazzua was one of a number of Hausa city-states which dominated the trans-Saharan trade after the collapse of the Songhai empire to the west. Its wealth was due to trade of mainly leather goods, cloth, kola, salt, horses and imported metals. At the age of sixteen, Amina became the heir apparent (Magajiya) to her mother, Bakwa of Turunku, the ruling queen of Zazzua. With the title came the responsibility for a ward in the city and daily councils with other officials. Although her mother's reign was known for peace and prosperity, Amina also chose to learn military skills from the warriors. Queen Bakwa died around 1566 and the reign of Zazzua passed to her younger brother Karama. At this time Amina emerged as the leading warrior of Zazzua cavalry. Her military achievements brought her great wealth and power. When Karama died after a ten-year rule, Amina became queen of Zazzua. She set off on her first military expedition three months after coming to power and continued fighting until her death. In her thirty-four year reign, she expanded the domain of Zazzua to its largest size ever. Her main focus, however, was not on annexation of neighboring lands, but on forcing local rulers to accept vassal status and permit Hausa traders safe passage. She is credited with popularizing the earthen city wall fortifications, which became characteristic of Hausa city-states since then. She ordered building of a defensive wall around each military camp that she established. Later, towns grew within these protective walls, many of which are still in existence. They're known as "ganuwar Amina", or Amina's walls. She is mostly remembered as "Amina, Yar Bakwa ta san rana," meaning "Amina, daughter of Nikatau, a woman as capable as a man.

      Theres tons of non-latin names out there. I think we do it a lot because the original planets were latin named. plus in science the universal naming language of species and such is latin. But again, theres many non-latin names for planets, solar systems, etc.....
