A day is time that elapses during an astronomical objects (in this case a moon) complete rotation around its own axis.
A year is time that elapses during objects complete rotation around its parent object (in our case its a planet Earth) which holds it in its orbit by gravitational force.
A day and a year on the Moon (Earths natural satellite, not any natural satellite) are almost equal in their duration, thus we may say that "one day on the moon is a year".
What else can I help you with?
Why is one day on the moon one year in earth time?
That is not true. One day on the Moon (the Earths natural satellite) is a time that elapses during its rotation around its own axis and is about 27 Earthly days. On the other hand, one Moon day is also one Moon year as it takes almost same time for Moon to finish orbit around Earth once.
How does a day on the moon compare to a year on the moon?
A day on the moon is about 29.5 Earth days long, which is roughly equivalent to a lunar month. A year on the moon, however, is about the same length as a year on Earth, as it takes the moon approximately 27.3 Earth days to complete one orbit around the Earth.
Why are a day and a year on the moon the same length give short answer?
A day and a year on the moon are the same length because the moon rotates on its axis at the same rate that it orbits around the Earth, causing one side of the moon to always face us. This synchronous rotation results in a day (one full rotation) on the moon taking the same amount of time as a complete orbit around the Earth (a year).
How long does it take for the moon to move through one full cycle?
a day or a year
How many days in one moon year?
A "Moon year" is almost exactly the same as an Earth year. That's about 365 Earth days. The Earth and Moon orbit the Sun in about 365.25 Earth days. So the answer is: about 365. If you mean how many "Moon days" in one Moon year, that's different. The Moon rotates in about 27.3 Earth days. That's one definition of a "Moon day". In that case the answer is about 365/27.3 days = about 13.37 days.
Why is a day in the moon the same lenght as a year on earth?
It isn't. A "day on the Moon" is about 29.5 Earth days; a year is about 365 days.
Why is a day in the moon the same length as a year on earth?
A day on the Moon (about 29.5 Earth days) is the same length as a year on Earth (365.25 days) because of a phenomenon called synchronous rotation. The Moon's rotation period is the same as its orbit around Earth, causing one side of the Moon to always face Earth, leading to equal lengths of day and year.
How many earth days is one year on the moon?
If a "day" is the time from one sunrise to the next, then on the moon, that's roughly 29 earth days.
How long does the moon take to rotate in one year?
it takes for one day 17 hours,14 minutes, and 24 seconds
Is a day and a year on the moon the same length?
A day on the moon is 29.5 Earth days. The moon takes 27.3 days to fully orbit the Earth. This is called a sidereal day.
Why are day and a year on the moon the same length?
Magic.
What would happen if the moon orbited earth in one day?
Techincally speaking that would never happen. The moon would have to be VERY close to the Earth. The moon moves away from the earth 1.75 inches away from the earth each year, making the hours of the day longer. If the moon did orbit the earth in one day, this would happen around the time period the moon formed in space.
