About 40.7% of that on Earth or about 2.46 times slower.
Increases.
the distance between Earth and the Moon in light years.
The period of a pendulum (for short swings) is about 2 PI (L/g)1/2. The gravity on the moon is less than that on Earth by a factor of six, so the period of the pendulum on the moon would be greater, i.e. slower, by about a factor of 2.5.
27.3 days around the earth.
The moon's orbital period is approximately 27.3 days.
The moon's orbital period around Earth is about 27.3 days. This is known as the sidereal month.
The moon's orbital period is the same as its rotational period, so the same side of the moon always faces the earth.
The Earth and Moon orbit the Sun together, a short distance apart compared with the size of the orbit. So, the Moon's orbital period is more or less identical with the Earth's. That's about 365.25 Earth days.
The orbital period of the moon with respect to the sun is approximately 29.5 days. This period is known as a synodic month, which is the time it takes for the moon to complete a full cycle of phases as observed from Earth.
The moon's "orbital period" is the length of time it takes the moon to make onecomplete revolution around the earth. That period of time is about two days lessthan the time it takes for the moon to go through all of its phases.
The moon's period of rotation on its axis is precisely synchronized with its period of orbital revolution around the earth. Both are 27.32 days.
The Moon's orbital period (time to orbit Earth) is about 27.3 days, which is the same as its rotational period (time to rotate once on its axis). This synchronous rotation is why we always see the same face of the Moon from Earth.
On the average, 365.24 days ... exactly the same as the earth's orbital period. If it were not exactly the same as the earth's orbital period, then the moon would either lead or lag the earth in the trip around the sun. It would certainly become noticeable ... if not immediately, then certainly over the course of a few hundred years. But that's not happening.
A state of `synchronous rotation`. Its where the rotational period of the moon is equal to orbital rotation period about Earth, one face of the moon will always appear to face earth. In our moons case this is due to tidal locking.
Synchronous rotation occurs when the moon's orbital period (the time it takes to orbit the Earth) and rotational period (the time it takes to rotate on its axis) are equal. This means that the same side of the moon always faces the Earth.
