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.

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.

How long is a day on Mimas?

One day on Mimas is equal to 23 hours.

Is Mimas the smallest moon in the solar system?

Mimas [MY-mas] is the seventh of Saturn’s known moons in order of orbit and is also the seventh largest. It is the 20th largest moon in the Solar System and is the thought to be the smallest to have its shape rounded by its own gravity.

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.

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.

How is Mimas round?

Overview. Less than 123 miles (198 kilometers) in mean radius, crater-covered Mimas is the smallest and innermost of Saturn’s major moons. It is not quite big enough to hold a round shape, so it is somewhat ovoid with dimensions of 129 x 122 x 119 miles (207 x 197 x 191 kilometers, respectively).

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.

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.

How high can you jump on Mimas?

Name	Gravity m/s²	Jump height metres
Mimas	0.06	76.57
Enceladus	0.11	43.04
Titan	1.35	3.60
Triton	0.78	6.24

Is Mimas a Death Star?

Mimas is a real “Death Star” in the Solar System.

Is there life on Mimas?

Scientists say Mimas’ ocean might support life, even if it is encased in ice. “Because the surface of Mimas is heavily cratered, we thought it was just a frozen block of ice,” Dr. Alyssa Rhoden, a specialist in the geophysics of icy satellites, said in a statement.

What type of moon is Mimas?

Is Mimas bigger than the moon?

Discovered in 1789 by Herschel. Mimas’ low density (1.17) indicates that it is composed mostly of water ice with only a small amount of rock. The surface of Mimas is dominated by an impact crater 130 km across, known as Herschel; it’s almost 1/3 of the diameter of the entire moon.

What is the biggest moon in the Milky Way?

Jupiter’s moon Ganymede is proving to be a fascinating world. Not only is it the largest moon in our solar system, bigger than the planet Mercury and the dwarf planet Pluto, but NASA’s Hubble Space Telescope has found the best evidence yet for an underground saltwater ocean on Ganymede.

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?

The planet venus orbits around sun is 225 days.

What planet has revolves 365 days?

Mars revolves around, or orbits, the sun in about 687 days. Earth is closer to the sun and revolves around it in about 365 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 is the rotation and revolution period of the Moon?

In fact, though we always see the same side of the Moon, the Moon is spinning. It’s just spinning at exactly the same rate as its orbit – one revolution every 27 days. Effectively, its day is as long as its year.

How many rotations of the Moon are in a year?

The orbit of the Moon around the Earth is not an easy process. The Moon makes a complete orbit around the Earth approximately once every 28 days. This means that the Moon orbits the Earth around 13 times in a year.
