Q:

What is bigger: the Earth or the Moon?

A:

Quick Answer

The Earth is much bigger than the moon. While the Earth is measured at 8,000 miles in diameter, the Moon only measures 2,160 miles in diameter. This means that if the Earth was hollowed out, the Moon could fit inside it 50 times.

Full Answer

Sometimes the Moon will appear larger in the sky than it usually does. This is due to an optical illusion. For instance, the Moon's orbit is not circular. As a result of this, sometimes the Moon is closer to Earth than at other times. When the Moon is full and at its closest to the Earth, it appears 14 percent larger and 30 percent brighter than it usually does.

  • Q:

    How fast does the moon orbit the Earth?

    A:

    The moon orbits the Earth at approximately 2,288 miles per hour and completes one full orbit every 27.322 days. Additionally, the moon takes approximately 27 days to complete one full rotation on its own axis, called its rotational period, which closely matches its orbit around Earth.

    How long does it take for the moon to orbit around the Earth one time?

    A:

    It takes the moon 27.3 days to make one revolution around the Earth, traveling at a speed of 2,300 miles per hour. The moon takes the same amount of time to make a full rotation on its axis, according to Windows to the Universe.

  • Q:

    Why does the same side of the moon always face Earth?

    A:

    Though the moon does rotate around its axis, the speed with which it completes these revolutions match the amount of time it takes to orbit around the Earth, leading the same side to be faced toward Earth at all times. This process takes a about month, meaning the moon's days are as long as an Earth month.
