How long does it take for Mimas to rotate?
How long does it take for Mimas to rotate?
At a mean distance just over 115,000 miles (186,000 kilometers) from the massive planet, Mimas takes only 22 hours and 36 minutes to complete an orbit.
Why is Mimas round?
It is named after Mimas, a son of Gaia in Greek mythology. With a diameter of 396 kilometres (246 mi), it is the smallest astronomical body that is known to still be rounded in shape because of self-gravitation.
Why is Mimas considered weird inside?
Mimas’ rotation and its orbit around Saturn make the moon look like it’s rocking and back forth and oscillating similar to the way a pendulum swings. Heexpects it must be caused by the moon’s weird interior.
What is the Mimas paradox?
Geologically speaking Mimas is dead, while Enceladus is still spouting great geysers of water ice into its atmosphere, along with a range of organic compounds. This paradox of Saturn’s moons has been explained, in part at least, by the higher density of Enceladus, which likely has a much greater rock content.
What is the temperature of Mimas?
The surface is icy and heavily cratered. Mimas has a low density, meaning it probably consists mostly of ice. Because Mimas has such a low temperature of about -200C (-328F), the impact features may date back to the time of the moon’s creation.
What is Mimas made out of?
ice
The mean density of Mimas is only 1.15 times that of water, and its surface is primarily water frost. For these reasons, Mimas is believed to be composed principally of ice. It is very bright, reflecting more than 80 percent of sunlight falling on it.
Why does Mimas look like the Death Star?
The two objects’ similar shapes can be largely attributed to a giant basin on Mimas called the Herschel crater. This crater formed when an impactor collided with Mimas near the little moon’s equator about 4.1 billion years ago. A large, round indentation is also present on the Death Star.
How high can you jump on Mimas?
High jump
| Name | Gravity m/s² | Jump height metres |
|---|---|---|
| Phobos | 0.00 | 845.11 |
| Io | 1.80 | 2.71 |
| Ganymede | 1.43 | 3.41 |
| Mimas | 0.06 | 76.57 |
Is Mimas geologically active?
Among Saturn’s moons, Mimas has been something of a low-key cousin compared with its larger, more flamboyant relatives Titan and Enceladus. And it is geologically active, with plumes of water venting from a series of cracks in the crust near the moon’s south pole.
Where is Mimas located?
Saturn
Mimas orbits at a range of 185,520 kilometers (115,280 miles) from Saturn in a time of 22 hours and 37 minutes. This orbit makes Mimas the closest major moon of Saturn. Mimas is tidally locked to Saturn with one side always facing in toward its parent.
What is Mimas made up of?
Mimas’ mean density of 1.1479 ± 0.007 g/cm3 is just slightly higher than that of water (1 g/cm³), which means that Mimas is mostly composed of water ice, with just a small amount of silicate rock. In this respect, Mimas is much like Tethys, Rhea, and Dione – moon’s of Saturn that are primarily composed of water ice.
What is the orbital period of Mimas?
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 internal structure of Mimas?
Internal Structure. Mimas’ internal structure is currently unknown but recent data collected on Mimas’ rotation showed an interesting oddity to brought scientist to two theories as to how Mimas may be under its rocky, water-ice surface. During observations of Mimas’ rotation on its axis, it was noticed that Mimas wobbles.
How big is Mimas?
But there is more than meets the eye about this small, prolate (one axis is longer than the other by about 10%) moon. Mimas is the 7th satellite discovered orbiting Saturn and is the smallest celestial body (approximately 396 km (246 mi) in diameter) to be rounded by it’s on gravitation.
How long does it take Mimas to orbit around Saturn?
Mimas is the innermost of Saturn’s moons orbiting at a distance of approximately 185,520 km (115,326 miles) with an inclination of 1.5. Mimas takes approximately 22.55 hours to orbit around its parent. It is tidally locked to Saturn so only one side is facing Saturn at all times.
