Question

Which sentence in the passage can be used to conclude that Eris is a dwarf planet and not a planet?

Answer 1

Answer:

It has several other objects in its orbit , though few are as massive as itself.

Explanation:

A celestial body orbiting the sun is considered  a planet when its mass is more than sum of  all other celestial  bodies moving along with it in its orbit round the sun.

Answer 2

Eris is slightly more massive than Pluto. However, both of them are smaller than Earth's Moon.
This should conclude that Eris is a dwarf planet.
