Deimos, Moon of Mars

Deimos is a Moon that orbits round the planet Mars. Its mass is estimated/calculated at being 1,476,188,406,600,740 kg. Its density has been calculated at being 1.471. Its volume is 998.

It was discovered in the year 1877 by A. Hall.

The Equatorial Radius of the object is 6km. The value is the radius in km of the said object at the Equator.

The Escape Velocity of the object is 20 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 equatorial circumference of Deimos is 39.0 km. The surface area of Deimos is 483.05. The surface gravity of the said item is 0.003. The Mean orbit velocity, that is the speed at which it orbits is 4864.80 km/h. The is the average distance in km of the object is from its parent 23458.00.

The orbital eccentricity is 0.0002, it is the degree at which Deimos orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
