# Amalthea, Moon of Jupiter

**Amalthea** is a Moon that orbits round the planet Jupiter. Its orbit circumference, the total distance it travels round its planetary parent is 1,139,766.90 km. The furthest it gets from its orbital parent (apoasis) is 181,980 km. Its mass is estimated/calculated at being 2,068,162,437,674,130,000 kg. Its density has been calculated at being 0.849 g/cm3. Its volume is 2,434,264 km3. It was discovered in the year 1892 by Edward Emerson Barnard. Its orbital period, i.e. the period it takes to complete an orbit round Jupiter is 0.498 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 181,400 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 2,068,162,437,674,130,000 kg. The equatorial circumference of Amalthea is 524.3 km. The mean radius of Amalthea is 83.45 km. The surface area of Amalthea is 87,510.98 km2. The surface gravity of the said item is 0.020 m/s2. The average orbit velocity, that is the speed at which it orbits is 95,362.0 km/h.

The orbital inclination, the angle at which Amalthea orbits in relation to the orbital plane is 0.38 degrees. The orbital eccentricity is 0.0032, it is the degree at which Amalthea orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
