How does the moon compare to Earth?

The moon is Earth's only natural satellite and is often compared to Earth because of their close proximity. However, the moon is vastly different from Earth in many ways. Here are some of the ways in which the moon compares to Earth:

• Size: The moon is much smaller than Earth. Its diameter is about one-quarter of Earth's diameter.
• Gravity: The moon has only about one-sixth the gravity of Earth.
• Atmosphere: The moon has no atmosphere, unlike Earth, which has a thick atmosphere that provides oxygen for living organisms.
• Temperature: The moon's temperature varies greatly, with a range of -173°C (-279°F) to 127°C (261°F), while Earth's temperature is more moderate.
• Water: The moon has no surface water, while Earth is covered with about 71% water.
• Day and Night: The moon has no day and night cycle like Earth. One day on the moon lasts about 29.5 Earth days.

Despite their differences, the moon and Earth are still closely connected, with the moon affecting Earth's tides and having a significant impact on our planet's overall climate.
