What is the Moon?
A: The Moon is an astronomical body that orbits planet Earth and is Earth's only permanent natural satellite.

It is the fifth-largest natural satellite in what?
A: The Solar System.

It’s the largest among planetary satellites relative to what?
A: The size of the planet that it orbits.

The Moon is the second-densest satellite in the Solar System, after what other moon?
A: Io.

The Moon is exceptionally large relative to what?
A: Earth. Its diameter is more than a quarter and its mass is 1/81 of Earth's.

The Moon is thought to have formed about how long ago?
A: 4.51 billion years ago.

The most widely accepted explanation is that the Moon formed from the debris left over after what?
A: After a giant impact between Earth and a Mars-sized body called Theia.

The Moon is in synchronous rotation with Earth, and thus always shows what?
A: The same side to Earth, the near side.

The near side is marked by dark volcanic maria that fill the spaces between what?
A: The bright ancient crustal highlands and the prominent impact craters.

After the Sun, the Moon is the second what?
A: The second-brightest regularly visible celestial object in Earth's sky.

Its surface is actually dark, although compared to the night sky it appears what?
A: Very bright, with a reflectance just slightly higher than that of worn asphalt.

Its gravitational influence produces what?
A: The ocean tides, body tides, and the slight lengthening of the day.

This is about thirty times the diameter of what?
A: The earth.

The Moon's apparent size in the sky is almost the same as that of what?
A: The Sun, since the star is about 400 times the lunar distance and diameter.

Therefore, the Moon covers the Sun nearly precisely during a what?
A: A total solar eclipse.

This matching of apparent visual size will not continue in the far future because the Moon's distance from Earth is what?
A: Gradually increasing.

How many manned landings were there between 1969 and 1972?
A: Six.

These missions returned what?
A: Lunar rocks which have been used to develop a geological understanding of the Moon's origin, internal structure, and the Moon's later history.

The lunar rocks from the Apollo program had the same isotopic signature as rocks from where?
A: Earth, however they differed from almost all other bodies in the Solar System.

Since the Apollo 17 mission in 1972, the Moon has been visited only by what?
A: Unmanned spacecraft.

In literature, especially science fiction, "Luna" is used to distinguish the earth’s moon from what?
