How big is Mimas?

How big is Mimas?

How small is Mimas?

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).

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.

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 big is Titan vs moon?

Size and Distance Titan has a radius of about 1,600 miles (2,575 kilometers), and is nearly 50 percent wider than Earth’s moon.

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.

Is the moon oversized?

The Moon’s seeming bigness is an actual illusion, rather than an effect of our atmosphere or some other physics.

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.

How high can you jump 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.

Is Mimas habitable?

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.

Is Titan moon bigger than Pluto?

Titan is larger than the planet Mercury and more massive than Pluto, and, in significant ways, it resembles a planet more than it does a typical moon.

Which moon is the 5th largest?

Tethys is Saturn’s fifth largest moon. Its irregular shape is 331 miles (533 kilometers) in mean radius, with dimensions 669 x 657 x 654 miles (1076.8 x 1057.4 x 1052.6 kilometers).

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.

What is the largest moo?

Size and Distance. 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.

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.

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.

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.
