How far is Pluto away from Eris?

Answer 1

Both Pluto and Eris (a "dwarf planet" even further from the Sun than Pluto) are constantly moving in their own orbits. Sometimes they may be on opposite sides of the solar system, and at other times they won't be too far apart (as planets go).

Answer 3

Eris has a very eccentric orbit. At the moment, it is approximately 96.6 AU from the sun (its aphelion is 97.5 AU), but about the year 2257 it will be at its perihelion of 37.9 AU, which will be closer to the sun than Pluto. Neptune's average distance from the sun is 30.1 AU.

Therefore, depending upon where each planet is in its respective orbit, the distance could be anywhere from about 1 billion kilometers to over 19 billion km.

Answer 4

Pluto and Eris are both dwarf planets in the outer solar system. On average, Pluto is about 9 billion kilometers away from Eris. The exact distance varies as the dwarf planets move in their orbits around the sun.

Answer 5

Eris is about 28.5 AUs from Pluto
