What is the rotational period of Mimas?
What is the rotational period of Mimas?
Moons of Saturn Mimas is one of the smallest spheroid bodies that we know in the solar system. It orbits at just under 200,000 km from Saturn and is about 400 km in diameter. The orbital period of Mimas is extremely short (0942 days), the order of 22h30mn, so it rotates at full speed around the planet Saturn.
How long is a day on Mimas?
One day on Mimas is equal to 23 hours.
What is the orbital radius of Mimas?
The orbital radius of Mimas is 1.87 × 108 m. The time taken to complete one revolution by Mimas around Saturn is approximately 23 hours.
What is Mimas atmosphere?
Mimas has no detectable atmosphere and no magnetic field.
Which planets rotational period is 243 days?
Venus is unusual because it spins the opposite direction of Earth and most other planets. And its rotation is very slow. It takes about 243 Earth days to spin around just once. Because it’s so close to the Sun, a year goes by fast.
How long is a year on Mimas?
Why is Mimas called the Death Star?
Mimas, Saturn’s cryptic-looking moon, is awfully deceptive. The small moon is dominated by an 80-mile-wide crater, giving it the appearance of the grim Star Wars Death Star — a space station equipped with a planet-destroying weapon.
How high can you jump on Mimas?
| Name | Gravity m/s² | Jump height metres |
|---|---|---|
| Mimas | 0.06 | 76.57 |

Why is Mimas round?
In fact, with a diameter of 396 km (246 mi), Mimas is just barely large and massive enough to achieve hydrostatic equilibrium (i.e. to become rounded in shape under the force of its own gravitation). Mimas is the smallest known astronomical body to have achieved this.
What is Mimas crater called?
Herschel (/ˈhɜːrʃəl/) is a large crater in the leading hemisphere of the Saturnian moon Mimas, centered on the equator at 112° longitude. It is named after the 18th-century astronomer William Herschel, who discovered Mimas in 1789.
Is Mimas prograde or retrograde?
Mimas measures about 400 km (250 miles) in diameter and revolves around the planet in a prograde, near-circular orbit at a mean distance of 185,520 km (115,277 miles).
What is the diameter of Mimas?
What planet does Mimas orbit?
An icy puzzle Traveling only 115,280 miles (185,520 km) from Saturn, Mimas is the closest major moon orbiting the planet.
Does Mimas orbit Saturn?
Is Mimas a sphere?
Because Mimas is nearly spherical, the wobble hinted that something lumpy, or perhaps sloshy, lay beneath the surface. The scientists tested several models of the moon’s interior to see what might give rise to the observed wobble.
Which planet has a rotation of 244 days?
Movement. 225 days – the orbital period of the planet Venus – the time taken to orbit the Sun in Earth days (224.701 days). 244 days – the rotation period – the time taken for the planet to rotate on its own axis (243.686 days).
What planet revolves in 225 days?
Venus is the second planet of the solar system and it takes 225 days to complete one revolution. Q. How many days does Venus take to complete one orbit around the Sun?
Which planet’s period of revolution is 224 days?
Venus: Its atmosphere is approximately 92 times dense than that of Earth. It takes 243.025 Earth days to rotate around its axis 224.65 Earth days to revolve around the sun.
What is the moons rotational period?
With more reading I learned that it takes about the same amount of time for the moon to rotate on its axis (27.3 days) as it does for the moon to make one revolution around Earth (29.5 days).
What is the time period of moon rotation?
The moon’s time period of rotation is equal to the moon’s time period of revolution which is 27.3 days.
How do you find the rotational period?
Calculating Planetary-Rotation Periods The planetary-rotation period can even be calculated from the velocity-distance-time equation, T = D/V, where D = distance, in this case the circumference (2πR), and V = tangential velocity.
What are the 2 periods of lunar rotation?
Lunar periods The sidereal month is the time it takes to make one complete orbit around Earth with respect to the fixed stars. It is about 27.32 days. The synodic month is the time it takes the Moon to reach the same visual phase. This varies notably throughout the year, but averages around 29.53 days.
