Do we ever see another side of the moon?
As the Earth is much larger than the Moon, the Moon’s rotation is slowed down until it reaches a balance point. As this NASA animation shows (right), this means that the same portion of the Moon always faces towards the Earth, and we can never see the far side.
Are there any undiscovered moons in the solar system?
Uranus may have small, undiscovered moons and there are likely more to be found elsewhere. Both probes zoomed by Jupiter and Saturn, and Voyager 2 continued on to see Uranus and Neptune. The spacecraft made many discoveries, including finding several moons at each system.
Is the far side of the Moon visible from Earth?
The far side of the Moon is the lunar hemisphere that always faces away from Earth, opposite to the near side. About 18 percent of the far side is occasionally visible from Earth due to libration. The remaining 82 percent remained unobserved until 1959, when it was photographed by the Soviet Luna 3 space probe.
How can we see the other side of the moon?
The reason we only see the one face is because of a phenomenon known as “tidal locking.” The moon rotates on its axis roughly once every 27 days, which is the same amount of time it takes to orbit the Earth.
Do moons have satellites?
Yes, the Moon could have a sub-satellite. If we look at a system of the Earth, Moon, and a sub-satellite, the same idea as above applies. The Moon has its own Hill sphere with a radius of 60,000 km (about one sixth of the distance between the Earth and Moon) where a sub-satellite could exist.

Why can we only see one side of the Moon?
However, the underlying reason why the moon rotates at this exact speed, forcing us to only see a single side of it, is because the moon has been tidally locked to the earth.
Does the Moon rotate?
Be a little careful . . . the Moon does rotate. If you stood on the Moon, the stars would rise and set, just like they do on Earth, except that a lunar day is a month long, the same as the Moon’s orbital period.
Why does the Moon always turn its face backwards?
As the Moon turns, feeling the Earth’s gravity, this creates friction within the Moon, slowing the Moon’s rotation down until its rotation matches its orbital period exactly, a state we call tidal synchronization. In this state, the Moon’s tidal bulge is always aligned with Earth, which means that the Moon always keeps one face toward Earth.
How long does it take for the Moon to orbit Earth?
Due to locking, the time taken for the Moon to rotate once on its axis and to orbit Earth is both 27.32 days. This is why we see only one side of the Moon. Tidal locking results in the Moon rotating about its axis in about the same time it takes to orbit Earth.
