  1. Question

    Will the next planet NASA will explore be Eris?

    No, Eris is simply too far away. It would take about 20 years for a spacecraft to reach Eris. The good news, however, is that we do have a spacecraft called New Horizons that is headed for a similar dwarf planet, Pluto. Read about it at http://pluto.jhuapl.edu/.
