The earth does not rotate around the sun. The proper term is revolve and it takes a year because that is the definition on a year. It takes the Earth approximatley 365 days to make one trip around the sun.
Actually it takes 365 1/4 days a year to revolve around the sun. That is why we have leap years
What else can I help you with?
What shape is the earths revolution?
If by revolution you mean the spin on it's own axis this is more or less a perfect circle. If you are referring to it's orbit around the sun, this is elliptical, not a perfect circle.
What is the difference between a planet's rotation and a planet's revolution?
Earth rotates on its axis and it revolves around the sun. Both things conserve earth's angular momentum. Each rotation is a day, and each solar revolution is a year. The days and years both help us mark the passage of time. Other than that, there are not too many similarities.
How many days for Earth to make one revolution?
365 day, that's how we measure 1 year
Is the length of the whole day 24 hours because the earth takes 24 hours to make a complete revolution?
True
How long does it take for a satellite to orbit round earth?
I believe that is around 90 minutes or about an hour and a half. I'm pretty sure of that.

How long does it take for the moon to make 1 revolution around the earth?
27 days.
How long do it take to make Saturn make one revolution around the sun?
About 29.5 Earth years.
How long does it take earth to make a revolution on its axis?
Earth takes 24 hours to revolve on its axis. A revolution is orbiting around the sun and not on its axis.
How long does it take for the moon to make one revolution around the Earth?
A lunar cycle is the time it takes for the moon to make a full revolution around the Earth. It takes about 29.5 days.
How long does it take for Uranus to make a full revolution around the sun?

One revolution around the Sun takes a year.
How long does it take Neptune to make one revolution around the Sun in earth time?
Neptune takes about 165 Earth years.
Why is a year on Mars twice as long as a year Earth?
It takes mars twice as long to make a full revolution around the sun than it takes earth.
How long does it take for the Earth to make a full revolution around the sun?
It takes the Earth approximately 365.25 days to make a full revolution around the sun, which is why we have a leap year every four years to account for the extra quarter day.
