After Eris was discovered, scientists had to decide whether to count it as a planet. Why did this make them question whether Pluto should still be counted as a planet?
a
because Pluto and Eris are both space objects
b
because Pluto and Eris were discovered at the same time
c
because Pluto and Eris are very different
d
because Pluto and Eris are very similar

Answer:

After Eris was discovered, they had to decide whether Eris was a planet or not. If they decided it wasn't a planet, they had to also decide whether Pluto should be counted as a planet since Eris and Pluto were quite similar. They were the same size, and they were both part of the Kuiper Belt.

Explanation:

Planets are the celestial bodies that are not fixed. Pluto should be counted as a planet was a question as both Pluto and Eris were similar.

Pluto is now considered a dwarf planet and is found in the Kuiper belt that is present beyond the planet, Neptune. Similarly, Eris is also a dwarf planet.

Eris is the second-largest dwarf planet and is very similar to Pluto. The discovery of Eris questioned whether Pluto should be considered a planet.

Both the planets Pluto and Eris were similar in size and were part of the Kuiper Belt leading to the question of whether they should be a planet or not.

Therefore, option d. Pluto and Eris are very similar.
