Which is the moon-like planet?

Correct option is A

Mercury is often considered a moon-like planet due to its similarities with Earth's Moon. It is a small, rocky planet with a heavily cratered surface, much like the Moon. Mercury has no atmosphere to speak of, which makes its surface features more pronounced, just as they are on the Moon. Its surface is also marked by plains, ridges, and impact craters, resembling the lunar surface. Mars and Earth, although rocky planets, have substantial atmospheres and other features that distinguish them from the Moon. Therefore, Mercury is the best choice for a moon-like planet.
Information Booster
· Mercury: Smallest planet in the solar system, heavily cratered, and lacks a significant atmosphere, making it similar to the Moon.
· Mars: Though rocky, it has a thin atmosphere, polar ice caps, and visible signs of ancient water flow, differentiating it from the Moon.
· Earth: Not comparable to the Moon due to its dense atmosphere, liquid water, and vibrant ecosystem.
· Surface Similarities: Both Mercury and the Moon have barren surfaces due to their inability to retain an atmosphere.
· Temperature Variations: Like the Moon, Mercury experiences extreme temperature variations due to its lack of atmosphere.
Additional Knowledge
Mercury
· Its surface, made of silicate rock and dust, is heavily cratered and lacks weathering due to the absence of an atmosphere.
· Temperatures range from extremely hot during the day to freezing at night.
Mars
· Mars has a thin atmosphere of carbon dioxide, visible polar ice caps, and evidence of past water, making it less similar to the Moon.
Earth
· Earth is vastly different from the Moon due to its thick atmosphere, oceans, and active tectonics.
