Janus is a Moon that orbits round the planet Saturn. It is also know by other designations, SX, S/1980 S1. Its mass is estimated/calculated at being 1,892,818,231,001,750,000 kg. Its density has been calculated at being 0.63. Its volume is 3003016.
It was discovered in the year 1966 by Audouin Dollfus.
The orbital period, i.e. the period it takes to complete an orbit round Saturn is 0.6945 days. The figure is also known as the sidereel period. The figure comes from N.A.S.A..
The Equatorial Radius of the object is 90km. The value is the radius in km of the said object at the Equator.
The Escape Velocity of the object is 191 km/h. The Escape Velocity is the speed an object needs to be travelling in order to break free from the objects gravity. The larger an object is, the more velocity (speed) is needed to break free from the object.The Semi-Major Axis of the orbit is 151.472, which is the furthest point from the centre to the edge of an elliptical point.
The equatorial circumference of Janus is 562.3 km. The surface area of Janus is 100,659.77. The surface gravity of the said item is 0.016. The Mean orbit velocity, that is the speed at which it orbits is 57052.80 km/h. The is the average distance in km of the object is from its parent 151460.00.
The orbital inclination, the angle at which Janus orbits in relation to the orbital plane is 0.14 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.
