Hydra, Moon of Pluto

Hydra is a Moon that orbits round the planet Pluto. Its mass is estimated/calculated at being 989,121,165,844,147,000 kg. Its density has been calculated at being 5. Its volume is 195432.

Hydra was discovered on June, 2005 by Hal Weaver et al..

The Equatorial Radius of the object is 36km. The value is the radius in km of the said object at the Equator.

The Escape Velocity of the object is 218 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 Hydra is 226.2 km. The surface area of Hydra is 16,286.02. The surface gravity of the said item is 0.051. The Mean orbit velocity, that is the speed at which it orbits is 443.70 km/h. The is the average distance in km of the object is from its parent 64749.00.

The orbital eccentricity is 0.0051, it is the degree at which Hydra orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
