1. Both Pluto and Eris are SMALLER than any of the terrestrial planets.
2. Both Pluto and Eris travel in MORE ELLIPTICAL orbits than any of the terrestrial or jovian planets.
3. Both Pluto and Eris are LESS MASSIVE than any of the terrestrial or jovian planets.

Answer 1

Answer:

1. Both Pluto and Eris are SMALLER than any of the terrestrial planets.

2. Both Pluto and Eris travel in MORE ELLIPTICAL orbits than any of the terrestrial or Jovian planets.

3. Both Pluto and Eris are LESS MASSIVE than any of the terrestrial or jovian planets.

Explanation:

All the above-mentioned options are the differences between Pluto, Eris and other terrestrial and Jovian planets in our solar system.

Some characteristics of Pluto include:

1. It has a mass of $1.27 * 10^{22} kg$
2. It has a diameter of 2,370 km (1,473 miles)
3. It has five (5) moons (Charon, Nix, Hydra, Kerberous, and Styx)

Some characteristics of Eris include the following:
