Pluto, Eris, and the Dwarf Planets of the Outer Solar System

For More Webcasts: www.nasm.si.edu Pluto, Eris, and the Dwarf Planets of the Outer Solar System Presenter: Mike Brown Tuesday, March 20, 2007 The Kuiper Belt is a mysterious region beyond Neptune and stretching more than four billion miles from the Sun. Using powerful telescopes, scientists are scouring the Belt and beyond, finding hundreds of small frigid objects such as Eris, which is larger than Pluto and takes 560 years to orbit the Sun; and smaller Sedna, with an elliptical orbit that takes more than 10000 years to complete. Join Mike Brown as he describes the hunt for these ancient and elusive worlds. Mike Brown is Professor of Planetary Astronomy at the California Institute of Technology and the discoverer, along with colleagues, of Eris (formerly 2003 UB313), Sedna, and other distant bodies. The 2007 Exploring Space Lectures, Journey Through the Outer Solar System, will feature four world-class scholars discussing current missions to the distant realm of the gas giants, the icy Kuiper Belt, and beyond.

why blame neptune? if they keep going they will dicover more of em and it will look like an atom.
we are just an atom among thounds, on a lagre string of vibration among others.
now tell me we are the only thing in the whole galaxy, that lives….sad itl take proberly 1000s of years for us to move out past plutos ect, thats if the planet is still here lol…(wish i was imortal =-[ )

Cosmic rays must be fast-moving things on camera?
Mike Brown is a great astronomer!

Of course, his alien example works now, however, earlier in my life Pluto was orbiting inside Neptune and so our alien friends might well have considered Pluto to be a something special.

he looks like Bill Gates

@Omnignosis well no because the sun needs crushing mass to crush itself into ignition. All those atoms and getting pushed together. They are vibrating in smaller and smaller spaces so they get faster and faster and so as you get soooo much energy in such a small space it brings the atoms into ignition speeds when they colide and bang, Fussion starts. The sun expanding will not add the mass that jupiter needs to make this happen, but it will heat it more.

@gmanzeroalpha
Will the Sun ignite Jupiter when is gets older and swells?

i click on it just to comment about its length longest you tube video ive ever seen

I compeletely agree. I see Jupiter as the dual star sister to the sun with the sun having grabbed too much hydrogen for that to happen. A little more and it would have been two stars in out solar systems. And with so many binary systems out there it s then even more likely that there will be plent of Sols and Jupiters that never quite made it, out there.

Yes, I like the subject matter, and the details the expert brings to point, but all that is said here could have been said in one third the time. Thanks. Sincerely, Goodold

this fella is on Science Channel all the time

is this a clone of Bill Gates?

fix your audio

is this the thing everyone is scared of is this the nibiru

aliens can’t find us yet cause our tvs radios dvds stuff like that stop radio transmission meaning they won’t notice this planet’s life source. if we can some how stop every thing that cause disturbence like that then after many years aleins might just notice us. ofcourse some of u don’t believe in aleins but there are too many planets to judge that at all.

Please pay atention at the 0:23:07 moment in this video.I think Eris is orbiting not only our sun maybe is orbiting our binar star to, becose it s to distant from the sun and when it s to far away the other star and his gravity pulls Eris

hey please
October 28th, 2010 at 2:54 am
oh i see. man, you know whats really going to suck, is, when hundreds and hundreds of years later, when aliens finally recover the, then battered up Voyager 1 probe, if they judge planets by the same scale by we do now, they will be so confused as to why pluto is there

time travelling Disney employee? lol. Ok!
October 28th, 2010 at 3:48 am
the size of pluto does not make it a dwarf planet, its the company that it keeps. Mercury has cleared its own orbit around the sun while Pluto is in the Kuiper Belt (consider it like an asteroid belt) and is far from alone.
October 28th, 2010 at 4:20 am
Wrong.
Fact: Pluto was named for itself by a time traveling Disney employee to gain fame for the Disney cartoon dog of the same name.
October 28th, 2010 at 4:26 am
lol
October 28th, 2010 at 4:34 am
Pluto was not named after a cartoon dog the cartoon dog was named after Pluto. Pluto is the god of the underworld.
October 28th, 2010 at 4:48 am
what about mercury. is it small enough to be considered a dwarf planet, even though it doesn’t match the other qualification of being icy

Sorry to change the subject but this is space-related.
To see a partial summary of the clear evidence that the Apollo moon missions were faked, google “The Naked Scientists”. In the “New Theories” section of the forum there’s a thread entitled “Did We Land on the Moon?”. The summary is on page 15. It’s the 7th one from the top.
Once people have seen the hoax evidence, there’s nothing anyone can do to make them believe we went to the moon.
Also, do a YouTube search on “MarsFaker”.
