planet help please quick?

Question

How long does it take for the Mars to orbit the sun? Explain?

Answer 1

Sir: I am not sure what you mean by quick...

But Mars orbits the Sun in 687 Earth days. That is how long it takes for the planet to swing all the way around the Sun in an eliptical orbit and return to the same spot again. Eliptical...
not a perfect circle shape...sort of a slightly squashed circle.

Mars also spins around while making this orbit. The rotational period for Mars is 24.62 Earth Hours. So it is spinning around as it orbits the Sun, and making one full spin in close to one Earth day which is 24 hours long.

Quick enough???

Answer 2

According to my physics book, the farther out something is, the slower it orbits. This makes sense, because the gravitational pull from the sun is much weaker, so it requires much less velocity for Mars to maintain an orbit without falling into the sun. And it can't be going faster, or else it would escape the sun's pull. So there's only one speed it can be going, and that is slower than Earth is rotating. And since it also has farther to travel, it winds up taking about 687 days to make one orbit.

Answer 3

Kepler's third law states that the square of the period is proportional to the cube of the average distance from the sun. P^2=a^3, where P is the time it takes for a planet to go around the sun measured in years and a is the distance of the planet from the sun measured in astronomical units ( the distance of the Earth from the Sun).For example, Jupiter is 5 astronomical units from the Sun, and a^3 = 5x5x5 = 125. What number times itself equals 125? Why, 11, close enough. And 11 years is the period for Jupiter to go once around the Sun. Do the math with the figures for Mars and you'll find that Kepler was pretty clever for his time.
