# Prospero, Moon of Uranus

**Prospero** is a Moon that orbits round the planet Uranus. Its orbit circumference, the total distance it travels round its planetary parent is 97,014,053.99 km. The furthest it gets from its orbital parent (apoasis) is 23,511,838 km. Its mass is estimated/calculated at being 98,912,116,584,414,800 kg. Its density has been calculated at being 1.5 g/cm3. Its volume is 65,450 km3.

Prospero was discovered on 18 July 1999 by Matthew J. Holman, John J. Kavelaars, Brett J. Gladman, Jean-Marc Petit, and Hans Scholl. Its orbital period, i.e. the period it takes to complete an orbit round Uranus is 1978.37 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 16,276,800 km, which is the furthest point from the centre to the edge of an elliptical point.

The mass of the object is calculated at being 98,912,116,584,414,800 kg. The equatorial circumference of Prospero is 157.1 km. The mean radius of Prospero is 25.0 (assuming an albedo of 0.07) km. The surface area of Prospero is 7,853.98 km2. The surface gravity of the said item is 0.011 m/s2. The average orbit velocity, that is the speed at which it orbits is 2,043.2 km/h.

The orbital inclination, the angle at which Prospero orbits in relation to the orbital plane is 151.83 degrees. The orbital eccentricity is 0.4445, it is the degree at which Prospero orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
