What is the length of time it takes to make a complete orbit around the sun?

Answer 1

A "year".

Orbital period.

The time differs for each of the planets, those close to the Sun orbit at a faster rate (angular velocity) than those further out so their "years" are shorter.

Answer 2

That depends on how far the planet is from the sun. The farther out it is, the longer it takes to complete an orbit. Mercury, the innermost planet, takes about 88 days to orbit the sun. Neptune, the outermost planet, takes 165 years.

Answer 3

The length of time it takes for a body to orbit its sun is called a year.
The length of year will vary depending on the distance the body is from the sun and the mass of the body and sun.

Answer 4

It depends on how far from it you are. If you're at the distance from it that Earth is, then it's just slightly under 365 and a quarter days. If you're at the distance from it that Mars is, it's more like 687 days.

Very roughly, for a circular orbit the square root of (0.0395 * ^3) gives you the length of the year in days (for our Sun ... the formula also depends on the mass of the sun and, technically, the mass of the planet, thought the mass of any planet in our solar system is so small compared to the mass of the Sun that it's negligible). I just checked that for Earth, Mars, Jupiter and Saturn, and in every case the number of days given by the formula was within 1% of the actual value, so it looks like I didn't mess up on the math when calculating it. Because the planets' orbits aren't completely circular, for "radius" you need to use what's called the "semi-major axis".

Answer 5

very slightly less than 365.25 days for earth

Answer 6

Yes, time is required for a body to orbit another body.

Answer 7

The Orbital Period of a planet describes the time that it takes a planet to make one orbit around the sun.

Answer 8

According to the calendar, 365.2425 days.

Answer 9

365 days
