it takes 365 days for the earth to go around the sun once.
Mercury is the closest planet to the sun thus Mercury has the shortest orbit duration. It takes the planet Mercury 88 days to rotate around the sun.
each planet has a different amount of time i takes to rotate around the sun so all i can say is that the closer you are te shorter and the farther you are the longer:)
23.56
One day
The planet Saturn takes about 10 hours and 39 minutes for it to rotate on its axis. Since the planet does not rotate uniformly the time does vary.
A planets day (solar day) is the time it takes to rotate once on its axis relative to the sun, the synodic period. A year on a planet is the time taken for the planet travel once around the sun.
1 year.
It very much depends which planet you mean, as it depends on dozens of factors! Referring to Earth, it takes one day (24 hours) to rotate once around it's own axis.
On the planet Venus, it takes 5,832 hours to complete a full rotation on the axis
1 1\2 year
365.243 days -- if you're talking about days it takes for the earth to revolve around the sun. For any planet to rotate around its own axis takes one day -- one of that planet's days. The moon, for instance, is tide-locked to the Earth, so one lunar day is very close to the 28-Earth-day orbital period.
The speed at which the planet moves and its distance from the sun both impact how long it takes to go around the sun. The bigger the orbit , the longer the planet's year.
