# Ophelia, Moon of Uranus

**Ophelia** is a Moon that orbits round the planet Uranus. Its orbit circumference, the total distance it travels round its planetary parent is 338,027.09 km. The furthest it gets from its orbital parent (apoasis) is 54,333 km. Its mass is estimated/calculated at being 53,952,063,591,499,000 kg. Its density has been calculated at being 1.3 g/cm3. Its volume is 41,052 km3. It was discovered in the year 1986 by R. Terrile, Voyager 2. Its orbital period, i.e. the period it takes to complete an orbit round Uranus is 0.376 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 53,800 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 53,952,063,591,499,000 kg. The equatorial circumference of Ophelia is 134.5 km. The mean radius of Ophelia is 21.4 km. The surface area of Ophelia is 5,754.90 km2. The surface gravity of the said item is 0.008 m/s2. The average orbit velocity, that is the speed at which it orbits is 37,458.7 km/h.

The orbital inclination, the angle at which Ophelia orbits in relation to the orbital plane is 0.104 degrees. The orbital eccentricity is 0.0099, it is the degree at which Ophelia orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
