Mimas was discovered on 17 September 1789 by William Herschel.
The orbital period, i.e. the period it takes to complete an orbit round Saturn is 0.94242 days. The figure is also known as the sidereel period. The figure comes from N.A.S.A..
The Equatorial Radius of the object is 198km. The value is the radius in km of the said object at the Equator.
The Escape Velocity of the object is 0.158912805 km/h. The Escape Velocity is the speed an object needs to be travelling in order to break free from the objects gravity. The larger an object is, the more velocity (speed) is needed to break free from the object.The Semi-Major Axis of the orbit is 185.52, which is the furthest point from the centre to the edge of an elliptical point.
The equatorial circumference of Mimas is 1245.3 km. The surface area of Mimas is 493,647.75. The surface gravity of the said item is 0.064. The Mean orbit velocity, that is the speed at which it orbits is 51559.80 km/h. The is the average distance in km of the object is from its parent 185539.00.
The orbital inclination, the angle at which Mimas orbits in relation to the orbital plane is 1.53 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.
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.
