# Ariel, Moon of Uranus

**Ariel** is a Moon that orbits round Uranus rather than the Sun which our Earth orbits round. Its orbit circumference, the total distance it travels round its planetary parent is 1,199,459.64 km. The furthest it gets from its orbital parent (apoasis) is 191,129 km. Its mass is estimated/calculated at being 1,294,849,526,195,970,000,000 kg. Its density has been calculated at being 1.592 g/cm3. Its volume is 1.592 g/cm3. It was discovered on 24 October 1851 by William Lassell.

The Semi-Major Axis of the orbit is 190,900 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 1,294,849,526,195,970,000,000 kg. The equatorial circumference of Ariel is 3,637.3 km. The mean radius of Ariel is 578.9 km. The surface area of Ariel is 4,211,307.59 km2. The surface gravity of the said item is 0.258 m/s2. The average orbit velocity, that is the speed at which it orbits is 19,832.3 km/h.

The orbital inclination, the angle at which Ariel orbits in relation to the orbital plane is 0.041 degrees. The orbital eccentricity is 0.0012, it is the degree at which Ariel orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
