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.
