What is the time of the rotation of the moon?
The Moon orbits Earth at a speed of 2,288 miles per hour (3,683 kilometers per hour). During this time it travels a distance of 1,423,000 miles (2,290,000 kilometers).
- Since the Earth spins faster than the Moon moves around it, the tidal bulges are dragged along with the Earth's surface faster than the Moon moves, and move "in front of the Moon".
- To break it down simply, a day on the Moon lasts as long as 29.5 Earth days. In other words, if you were standing on the surface of the Moon, it would take 29.5 days for the Sun to move all the way across the sky and return to its original position again.
- As such, the arms are moving through space. The sun and the solar system travel with them. The solar system travels at an average speed of 515,000 mph (828,000 km/h). Even at this rapid speed, the solar system would take about 230 million years to travel all the way around the Milky Way.
When you take a look up at the sky, the two most prominent objects are the Sun and the Moon. Just like you might expect, the Moon both orbits counterclockwise around Earth and rotates counterclockwise on its axis, so that the same side of it always faces us!
- Venus' slowing spin isn't the only peculiar thing about its rotation. Venus is unique in our solar system for being the only planet that spins clockwise; all the other planets spin counter-clockwise. This effect, called "retrograde" rotation, is another mystery about Venus that has yet to be adequately solved.

Answer 1: The orbit of the Moon around the Earth is not an easy process. The Moon makes a complete orbit around the Earth approximately once every 28 days. This means that the Moon orbits the Earth around 13 times in a year.
- See Understanding the moon phases). If the Moon didn't spin at all, then eventually it would show its far side to the Earth while moving around our planet in orbit. However, since the rotational period is exactly the same as the orbital period, the same portion of the Moon's sphere is always facing the Earth.
- At the beginning of the cycle, we cannot see the Moon because none of its illuminated side is pointed towards Earth. The Moon can sometimes appear in the sky during the daytime because it is the closest object to Earth, and because its orbital cycle means that sometimes it is brighter in the day than at night.
- We experience day when we are on the half of the Earth facing the Sun, and night once we have been spun around to the other side. The same occurs on the moon. However, the difference is that It takes 28.5 days for the moon to spin about its axis. So one moon-day is 28.5 Earth-days long!
