Q:

How much does the moon weigh?

Full Answer

The moon does have mass, which can be taken as a stand-in for weight. The moon's mass is roughly 7.3477×10^22 kilograms, or 73.5 million million million metric tonnes. This is the figure that would most likely register on a standard scale if the moon could be brought to Earth and weighed and if the Earth's gravity acted equally on all parts of the moon.

    Why do we have a moon?

    A:

    No concrete evidence explains why there is a moon. The best hypothesis presented is the Giant Impactor hypothesis: It suggests that around 4.45 billion years ago, while the Earth was still forming, a large object hit the Earth at an angle.

  • Q:

    Why does the moon appear bright?

    A:

    The moon appears bright because the side visible on Earth reflects the light from the sun. As the moon and the Earth move around their respective orbits, different portions of the moon are visible to people on Earth, depending on the angle at which the light hits the moon and reflects back to Earth. The moon reflects back about 12 percent of the light from the sun that hits it.
