The time it takes for a planet to complete one full rotation on its axis varies depending on the planet. For example, Earth takes approximately 24 hours to rotate once, while Venus takes about 243 Earth days. The length of a day on a planet is determined by its rotational speed and size.
The time it takes for a planet to complete one rotation on its axis is known as its sidereal day. For example, Earth takes approximately 24 hours to complete one rotation. Other planets like Venus have longer rotation periods, for instance 243 Earth days for Venus to rotate once.
The moon takes about 27.3 days to rotate once on its axis. This rotation period is almost the same as its orbital period around the Earth, which is why we always see the same face of the moon from Earth.
venus takes 243 earth days to complete one day. its days are actually longer than its years at it takes 225 earth days to orbit the sun.
No planet has a revolution and rotation that takes 27 days. The Moon rotates once every 27 days and revolves around the Earth once every 27 days.
Venus.
0.44401 days.
It depends which planet you mean - the Earth takes 23 hours & 56 minutes to rotate once.
it takes 365 days for the earth to go around the sun once.
Neptune takes 16 hours 6 minutes and 36 seconds to rotate or spin once on its axis, or 0.67125 Earth days.
Mercury. Its takes around 58.65 days to rotate once on its axis relative to background stars.
It takes Venus about 243 days to rotate once on its axis. This makes one day of Venus equal to 243 days on Earth.
Venus takes approximately 243 Earth days to rotate just once!
The Earth takes 23h56m to rotate once around its axis.
It takes 58.6 Earth days for Mercury to rotate on it's axis once.
That's a planet's 'day'. On the Earth - that's just under 24 hours (approx. 23 hours 56 minutes' On mercury, it's 88 days !
Venus has the slowest rotational period- 243 days to rotate once.
