Is Mimas bigger than the moon?

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.

How much gravity does a Mimas have?

Ceres has 2.9% of Earth’s gravity. Saturn’s moon Mimas has 0.6% of Earth’s gravity.

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.

What makes Mimas a distinct moon?

What makes Mimas a distinct moon? It suffered a huge meteorite impact that must have nearly shattered it.

What is the heaviest moon?

With a diameter of about 5,270 kilometres (3,270 mi) and a mass of 1.48×1020 tonnes (1.48×1023 kg; 3.26×1023 lb), Ganymede is the largest and most massive moon in the Solar System.

Which moon has the largest mass?

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.

Is Mimas bigger than Earth?

With a mean radius of 198.2 ± 0.4 km and a mass of about 3.75 ×1019 kg, Mimas is equivalent in size to 0.0311 Earths and 0.0000063 times as massive. Orbiting Saturn at an average distance (semi-major axis) of 185,539 km, it is the innermost of Saturn’s larger moons, and the 8th moon orbiting Saturn.

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.

Which is the smallest moon in the world?

The smallest moon is Deimos, at Mars, only seven miles in diameter, although its size now is rivaled by the small shepherd moons discovered by Cassini at Saturn and by others yet to be counted and named in the rings around Jupiter, Saturn …

What is the biggest and smallest moon?

Ganymede is the biggest moon in the Solar System, bigger than the planet Mercury and all the dwarf planets. At the same time, Io, Callisto, and Europa are smaller than Mercury but more prominent than all the dwarf planets.

What is unusual about Mimas?

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. The rocking motion is called libration, and it’s commonly observed in moons that are influenced by the gravity from neighboring planets.

Does Mimas have gravity?

Is there water on Mimas?

Saturn’s moon Mimas may be the newest, if not the most unlikely member of the solar system’s family of icy bodies with internal liquid water oceans, according to a new study by Alyssa Rose Rhoden of the Southwest Research Institute and Matthew E.

What is the 2 largest moon?

Titan is the second largest moon in our solar system. Only Jupiter’s moon Ganymede is larger, by just 2 percent. Titan is bigger than Earth’s moon, and larger than even the planet Mercury.

Which moon has water?

Scientists believe several moons within our solar system have significant subsurface liquid water deposits. Saturn’s moon Enceladus and Jupiter’s moon Europa are two examples. Both appear to have salty, liquid oceans covered with thick layers of ice at the surface.

Is moon hotter than Earth?

Since the Moon and the Earth are approximately the same distance from the Sun, they receive sunlight of the same strength. So the temperature of the Earth and the Moon should be the same. It is the Moon’s lack of atmosphere that creates such extreme temperatures.

Is Mimas bigger than Earth?

With a mean radius of 198.2 ± 0.4 km and a mass of about 3.75 ×1019 kg, Mimas is equivalent in size to 0.0311 Earths and 0.0000063 times as massive. Orbiting Saturn at an average distance (semi-major axis) of 185,539 km, it is the innermost of Saturn’s larger moons, and the 8th moon orbiting Saturn.

How large a moon is Miranda?

Overview. Like Frankenstein’s monster, Miranda looks like it was pieced together from parts that didn’t quite merge properly. At about 500 km in diameter, it’s only one-seventh as large as Earth’s moon, a size that seems unlikely to support much tectonic activity.

Why is Mimas weird inside?

There’s something strange going on below the surface of Saturn’s Death Star-looking moon Mimas, a new study suggests. 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. That rocking motion is called libration.
