Choose the correct statement about the Moon.

The Moon's diameter is about one half that of Earth and the gravity one quarter of Earth.

Scientists now believe the Moon is a dwarf planet captured by Earth nearly 4.2 billion years ago.

The Moon is nearly as large as Earth but with a gravity 1/6 that of Earth.

The Moon's diameter is one quarter that of Earth and the gravity is 1/6 that of Earth.

The correct statement about the Moon is:

The Moon's diameter is about one half that of Earth and the gravity one quarter of Earth.

To clarify:

  • The Moon's diameter is about 3,474 kilometers, which is roughly 27% that of Earth's diameter (about 12,742 kilometers), so it's close to half, but it's not accurate to say "about one half."
  • The Moon's gravity is approximately 1/6 that of Earth's gravity.

However, none of the options provided are perfectly accurate. The first option is the closest but still slightly inaccurate regarding the diameter.
