The sidereal day is the time it takes for a planet to rotate once. For Venus that's about 243 of our Earth days.
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.
One round trip around the sun is called a "YEAR".

One day.
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 world only take one day to rotate, x
59 day noy are uahppy
Earth takes a bit less than 24 hours to complete one rotation (day). The day on Mars is a bit longer at 24.6 Earth hours.

It takes Venus about 243 days to rotate once on its axis. This makes one day of Venus equal to 243 days on Earth.
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.

It takes any planet one day to rotate on its axis. A Martian day is only slightly longer than an Earth day: 24 hrs. 39 mins. 35 secs.
Our planet takes 24 hours (one day)
