Which sentence in the passage can be used to conclude that Eris is a dwarf planet and not a planet? Eris takes about 557 Earth years to orbit the Sun. It has a mean surface temperature of about 40 Kelvin. It has a nearly spherical shape. It has several other objects in its orbit, though few are as massive as itself. Eris is too far away and small to be clearly visible from the Earth. Scientists used its moon, Dysnomia, to measure it. Eris is believed to be slightly more massive than Pluto. However, both of them are smaller than Earth’s Moon. Eris orbits the Sun directly; it is not a satellite of another planet or dwarf planet.

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.

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.

Eris is believed to be slightly more massive than Pluto. However, both of them are smaller than Earth’s Moon.
