Cupid, Moon of Uranus

Cupid is a Moon that orbits round the planet Uranus.

Cupid was discovered on 25 August 2003 by M.R. Showalter and J.J. Lissauer.

The orbital period, i.e. the period it takes to complete an orbit round Uranus is 0.613 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 18km. The Equatorial Radius is based on the assumption of the Albedo value. The value is the radius in km of the said object at the Equator.

The albedo of the object is 0.07. The Albedo is the amount of radiation that is reflected back into space by the object.

The Semi-Major Axis of the orbit is 74.39, which is the furthest point from the centre to the edge of an elliptical point.

The Mean orbit velocity, that is the speed at which it orbits is 31771.20 km/h. The is the average distance in km of the object is from its parent 74392.00.

The orbital inclination, the angle at which Cupid orbits in relation to the orbital plane is 0.1 degrees. The orbital eccentricity is 0.0013, it is the degree at which Cupid orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
