# Janus, Moon of Saturn

**Janus** is a Moon that orbits round the planet Saturn. Its orbit circumference, the total distance it travels round its planetary parent is 951,640.25 km. The furthest it gets from its orbital parent (apoasis) is 152,490 km. Its mass is estimated/calculated at being 1,892,818,231,001,750,000 kg. Its density has been calculated at being 0.63 g/cm3. Its volume is 3,003,016 km3. It was discovered in the year 1966 by Audouin Dollfus. Its orbital period, i.e. the period it takes to complete an orbit round Saturn is 0.695 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 151,460 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 1,892,818,231,001,750,000 kg. The equatorial circumference of Janus is 562.3 km. The mean radius of Janus is 89.5 km. The surface area of Janus is 100,659.77 km2. The surface gravity of the said item is 0.016 m/s2. The average orbit velocity, that is the speed at which it orbits is 57,052.8 km/h.

The orbital inclination, the angle at which Janus orbits in relation to the orbital plane is 0.163 degrees. The orbital eccentricity is 0.0068, it is the degree at which Janus orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
