# Callirrhoe, Moon of Jupiter

**Callirrhoe** is a Moon that orbits round the planet Jupiter. Its orbit circumference, the total distance it travels round its planetary parent is 148,360,304.47 km. The furthest it gets from its orbital parent (apoasis) is 30,920,456 km. Its mass is estimated/calculated at being 869,227,691,196,372 kg. Its density has been calculated at being 2.6 g/cm3. Its volume is 333 km3.

Callirrhoe was discovered on 19 October 1999 by Jim V. Scotti, Timothy B. Spahr, Robert S. McMillan, Jeffrey A. Larsen, Joe Montani, Arianna E. Glea. Its orbital period, i.e. the period it takes to complete an orbit round Jupiter is 758.82 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 24,102,000 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 869,227,691,196,372 kg. The equatorial circumference of Callirrhoe is 27.0 km. The mean radius of Callirrhoe is 4.3 km. The surface area of Callirrhoe is 232.35 km2. The surface gravity of the said item is 0.003 m/s2. The average orbit velocity, that is the speed at which it orbits is 8,147.0 km/h.

The orbital inclination, the angle at which Callirrhoe orbits in relation to the orbital plane is 147.155 degrees. The orbital eccentricity is 0.2829, it is the degree at which Callirrhoe orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
