What is Mimas composed of?

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.

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.

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.

What makes Mimas special?

Mimas is an icy moon that’s 246 miles wide and whose most distinctive feature is the 88-mile-wide Herschel crater – a giant Cyclops-like indentation that makes the moon resemble the planet-obliterating superweapon from “Star Wars” that’s known as the Death Star.

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.

What are lunar maria mainly made of?

(Together with the bright lunar highlands, they form the face of the “man in the moon.”) Samples of lunar rock and soil brought back by Apollo astronauts proved that the maria are composed of basalt formed from surface lava flows that later congealed.

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.

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.

Is Mimas a Death Star?

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

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 temperature on 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 -200° C (-328°F), the impact features may date back to the time of the moon’s creation.

How fast does Mimas rotate?

Who was the biggest moon in universe?

Ganymede has a radius of 1,635 miles (2,631 kilometers) and is the largest moon in our solar system. It’s bigger than Mercury and Pluto. Ganymede is about 665,000 miles (1.07 million kilometers) from Jupiter, which orbits about 484 million miles (778 million kilometers) from the Sun.

Why does the face of Mimas face Saturn?

Like a lot of moons in the solar system, including our own, Mimas always shows essentially the same face to its parent planet. This is called a spin-orbit resonance, meaning the moon’s rotation, or spin, is in sync with its orbit around Saturn.

How high can you jump on Mimas?

Is Mimas the closest moon to Saturn?

An icy puzzle Traveling only 115,280 miles (185,520 km) from Saturn, Mimas is the closest major moon orbiting the planet.

What is a smiling moon called?

A wet moon (also called a Cheshire moon) is the visual phenomenon when the “horns” of the crescent Moon point up at an angle, away from the horizon, so that the crescent takes on the appearance of a bowl or smile.

Is Mimas a Death Star?

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