Moon, Moon of Earth

Moon is a Moon that orbits round the planet Earth. Its orbit circumference, the total distance it travels round its planetary parent is 2,413,402.16 km. Its mass is estimated/calculated at being 73,476,730,924,573,500,000,000 kg. Its density has been calculated at being 3.344 g/cm3. Its volume is 21,971,669,064 km3. It was discovered by Known by the Ancients.

The orbital period, i.e. the period it takes to complete an orbit round Earth is 27.322 days. The figure is also known as the sidereel period. The figure comes from N.A.S.A.. Its takes 27.322 Earth days to do a full rotation period.

The Semi-Major Axis of the orbit is 384,400 km, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Moon is 10,917.0 km. The mean radius, that is the average radius of Moon is 1737.5 km. The surface area of Moon is 37,936,694.79 km2. The surface gravity of the said item is 1.624 m/s2. The average orbit velocity, that is the speed at which it orbits is 3,680.5 km/h.

The orbital inclination, the angle at which Moon orbits in relation to the orbital plane is 5.16 degrees. The orbital eccentricity is 0.0554, it is the degree at which Moon orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
