# Ymir, Moon of Saturn

**Ymir** is a Moon that orbits round the planet Saturn. Its orbit circumference, the total distance it travels round its planetary parent is 141,259,079.59 km. The furthest it gets from its orbital parent (apoasis) is 30,862,351 km. Its mass is estimated/calculated at being 4,945,605,829,220,740 kg. Its density has been calculated at being 2.3 g/cm3. Its volume is 3,054 km3. It was discovered in the year 2000 by Brett J. Gladman, John J. Kavelaars, Jean-Marc Petit, Hans Scholl, Matthew J. Holman, Brian G. Marsd. Its orbital period, i.e. the period it takes to complete an orbit round Saturn is 1315.13 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 23,140,400 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 4,945,605,829,220,740 kg. The equatorial circumference of Ymir is 56.5 km. The mean radius of Ymir is 9.0 (assuming an albedo of 0.06) km. The surface area of Ymir is 1,017.88 km2. The surface gravity of the said item is 0.004 m/s2. The average orbit velocity, that is the speed at which it orbits is 4,473.9 km/h.

The orbital inclination, the angle at which Ymir orbits in relation to the orbital plane is 171.661 degrees. The orbital eccentricity is 0.3337, it is the degree at which Ymir orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
