# Cupid, Moon of Uranus

**Cupid** is a Moon that orbits round the planet Uranus. Its orbit circumference, the total distance it travels round its planetary parent is 467,418.52 km. The furthest it gets from its orbital parent (apoasis) is 74,489 km.

Cupid was discovered on 25 August 2003 by M.R. Showalter and J.J. Lissauer. Its 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 Semi-Major Axis of the orbit is 74,392 km, which is the furthest point from the centre to the edge of an elliptical point.

The mean radius of Cupid is 18 (assuming an albedo of 0.07) km. The average orbit velocity, that is the speed at which it orbits is 31,771.2 km/h.

The orbital inclination, the angle at which Cupid orbits in relation to the orbital plane is 0.099 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.
