# Mab, Moon of Uranus

**Mab** 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 614,092.44 km. The furthest it gets from its orbital parent (apoasis) is 97,980 km. It was discovered on 25 August 2003 by Mark R. Showalter and Jack J. Lissauer.

The Semi-Major Axis of the orbit is 97,736 km, which is the furthest point from the centre to the edge of an elliptical point.

The mean radius of Mab is 24 (assuming an albedo of 0.103) km. The average orbit velocity, that is the speed at which it orbits is 27,721.8 km/h.

The orbital inclination, the angle at which Mab orbits in relation to the orbital plane is 0.134 degrees. The orbital eccentricity is 0.0025, it is the degree at which Mab orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
