Which planet is the smallest among the terrestrial planets?

Explanation:
Among the rocky planets, Mercury is the smallest. Its diameter is about 4,880 kilometers, which is smaller than Mars (around 6,800 km), Venus (about 12,100 km), and Earth (about 12,740 km). Because it is so small in size, Mercury is also the least massive of the terrestrial planets. The other three are significantly larger, with Venus and Earth close in size and Mars notably larger than Mercury.
