Answer 1

Here's some good info. It's spelled Eros by theway.

Answer 2

Eris, a so-called dwarf planet, lies beyond Pluto in the far reaches of the solar system, and has been causing trouble since it was found in 2005.

Some scientists said tiny Eris wasn't a real planet, but that would mean the even smaller Pluto wasn't either. So both were re-named dwarf planets.

Eris was unsurprisingly named after the Greek goddess of trouble and arguments.

Eris was originally called Xena as a codename before a final name was decided.

Because it's so small and so far away, it's difficult to tell exactly how big it is.

One team of scientists think it is 70km wider than Pluto, while another think it is 700km bigger.

Eris' moon has a name too - Dysnomia, the daughter of Eris known as the spirit of lawlessness.

And Eris' troublesome nature is still causing problems - a band of scientists are now campaigning to get Pluto called a planet once more.

Answer 3

Images of Eris, or 136199 Eris were first taken in 2003, and it was discovered in 2005. In 2006 it was measured by the Hubble Telescope at a diameter of 2400 km. As such it is slightly larger than Pluto and the therefore the ninth largest object in our solar system.

Eris was originally referred to as "the 10th planet", but after a redefining of the word "planet", Eris, along with Pluto and Ceres, were labelled "dwarf planets".

It is located just beyond the Kuiper Belt, and has at least one moon, named Dysnomia.

Answer 4

Eris, was discovered in 2003. It was originally given the designation 2003 UB313. You can, of course, do a google search. But I'll tell you what little I know from the top of my head.

It's out there in the Kuiper Belt beyond the orbit of Neptune. Shortly after it's discovery, a moon was discovered, followed by a second moon a while later. 2003 UB313, according to recent observations by Hubble (before the primary camera died) showed it to be about 5% larger than Pluto itself.

Answer 5

Probably not - there aren't many known facts about it.

It's slightly larger than Pluto, too small to be classed as an actual planet, was discovered a couple of years ago and sits on the outside edge of the Kuiper belt.

I think.
