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.

Eris is 97 astronomical units away from the sun. ( an astronomical unit is the average distance between Earth and the Sun)
The sun does not orbit itself!
It takes Eris 557 years to orbit the sun
Eris orbital period is around 557 years.
Depending on where Eris is in its orbit, it can take anywhere from 16-29 years to get to Eris from Earth.

The word is "revolve" or "orbit", not "rotate". It takes Eris 560 years to orbit the Sun once.
203,830 days.
it takes 7 years for Eris to orbit 1 rotaion

A long time.
There is no Nibura, so I take it you mean Eris. The orbit of Eris will never allow it closer to us than billions of miles.
