Mimas is referred to as the Death Star moon because the crater looks like the giant weapon that Grand Moff Tarkin used to destroy the planet of Alderaan. The cause of the weapon look would have been caused by a meteorite smashing into it.
Mimas is a Moon that orbits round Saturn rather than the Sun which our Earth orbits round. Its orbit circumference, the total distance it travels round its planetary parent is 1,165,663.95 km. The furthest it gets from its orbital parent (apoasis) is 189,176 km. Its mass is estimated/calculated at being 37,505,676,206,690,400,000 kg. Its density has been calculated at being 1.15 g/cm3. Its volume is 1.15 g/cm3. It was discovered on 17 September 1789 by William Herschel.
The Semi-Major Axis of the orbit is 185,539 km, which is the furthest point from the centre to the edge of an elliptical point.
The mass of the object is calculated at being 37,505,676,206,690,400,000 kg. The equatorial circumference of Mimas is 1,245.3 km. The mean radius of Mimas is 198.2km (+/- 0.25). The surface area of Mimas is 493,647.75 km2. The surface gravity of the said item is 0.064 m/s2. The average orbit velocity, that is the speed at which it orbits is 51,559.8 km/h.
The orbital inclination, the angle at which Mimas orbits in relation to the orbital plane is 1.574 degrees. The orbital eccentricity is 0.0196, it is the degree at which Mimas orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
