Choose the correct statement about the Moon. 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.
