Eris orbital period is around 557 years.
11,013.05 years
A light year is a unit of space, not time. It is the distance light travels in a year. Eris is far less than a light year away.
It depends on the dwarf planet's distance. Pluto the most famous dwarf plant takes 248 years to orbit the sun.
Eris is a large dwarf planet beyond Neptune's orbit. From the launch date it would probably be the best part of 15-30 years, depending on the position of Eris. The New Horizons space probe was launched in January 2006 to investigate Pluto, which is a similar distance (29.7 - 49.3 AU). It should get to Pluto by the middle of 2015, even with an original speed of 36400 mph, and a gravitational boost from Jupiter. Eris' orbit is fairly eccentric, so at its closest it will be 37.7 AU (earth to sun distances - Astronomical Units). At its furthest it is 97.5AU.
550 years.
it takes 7 years for Eris to orbit 1 rotaion
The dwarf planet Eris best fits this description, with a year about 561 years long.
No, a dwarf planet is smaller than a planet but bigger than an asteroid, and dwarf planets tend to be a long way out, like Pluto and Eris.
No, there are no new planets in our solar system. They have all been here for a long time! Our solar system has eight planets, since Pluto was downgraded to a dwarf planet. There are some new dwarf planets: Eris, Ceres, and the newest MakeMake. There are about a dozen more candidates for dwarf planet status. Pluto, Eris, and MakeMake are also considered plutiods, which means they are beyond Neptune's orbit. See Related Links below for more information.
The dwarf planet 1 Ceres orbits around the Sun once in 4.6 years.

The word is "revolve" or "orbit", not "rotate". It takes Eris 560 years to orbit the Sun once.
Depending on where Eris is in its orbit, it can take anywhere from 16-29 years to get to Eris from Earth.
