The rotational period of the celestial sphere is simply the reflection of Earth's rotation; therefore, it rotates once every 23 hours and 56 minutes. You can determine that by observing the apparent movement of distant stars.
Haumea's rotational period is 3.9155 hours.
To determine the period of orbit for a celestial body, one can use Kepler's Third Law of Planetary Motion, which states that the square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. By measuring the semi-major axis of the orbit and the gravitational force acting on the celestial body, one can calculate the period of its orbit.
what is Saturn's moon Titan's rotational period
Saturn has a sidereal rotational period of 10.57 hours and a rotational velocity of 9.87 km per second. Because of its gaseous composition, it has a varying rotational period at the poles which is about 10 hours 45 minutes.
7.8 hours
Phobos, one of Mars' moons, has a rotational speed that allows it to complete one rotation on its axis approximately every 7 hours and 39 minutes. Interestingly, this rotation period is longer than its orbital period around Mars, which is about 6 hours and 9 minutes. As a result, Phobos rises in the west and sets in the east on Mars, a unique characteristic among celestial bodies.
Io's rotational period, or the time it takes for the moon to complete one full rotation on its axis, is approximately 42.5 hours. This means that a day on Io lasts around 42.5 Earth hours.
The rotational period of Venus is 243 Earth days.
Mars has a rotational period of 24.6 hours.
Pluto has a rotational period equal to 153.3 hours.
Rotation means the planet spinning about it axis. (Orbit the the path of the planet round the Sun). The planet Mercury has a rotational period of 58.646 Earth days. The planet Venus has a (retrograde) rotational period of 243.0185 Earth days. The planet Mars has a rotational period of 1.025957 Earth days. The planet Jupiter has a rotational period of 9.925 hours. Obviously Earth has a rotational period of 1 Earth day.
There are no planets in our solar system with a rotational period of 318 days. The longest is Venus, with a rotational period of 243 days.
