Carme, Moon of Jupiter

Carme is a Moon that orbits round the planet Jupiter. Its mass is estimated/calculated at being 131,882,822,112,553,000 kg. Its density has been calculated at being 2.6. Its volume is 50965.

The orbital period, i.e. the period it takes to complete an orbit round Jupiter is 734.2 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 23km. The Equatorial Radius is based on the assumption of the Albedo value. The value is the radius in km of the said object at the Equator.

The albedo of the object is 0.04. The Albedo is the amount of radiation that is reflected back into space by the object.

The Escape Velocity of the object is 100 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 23400, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Carme is 144.5 km. The surface area of Carme is 6,647.61. The surface gravity of the said item is 0.017. The Mean orbit velocity, that is the speed at which it orbits is 8210.20 km/h. The is the average distance in km of the object is from its parent 23404000.00.

The orbital inclination, the angle at which Carme orbits in relation to the orbital plane is 164.9 degrees. The orbital eccentricity is 0.2533, it is the degree at which Carme orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.

Not much is know about Carme, the only photograph we do have is shot from a distance. Carme was first discovered by Seth Barnes Nicholson in 1938 but it wasn't given its present day name until 1975. Carme wasn't the only one discovered, he also discovered three other moons. Up until 1975, they were simply known by Roman numerals IX (Sinope), X (Lysithea), XI (Carme) and XII (Anake). Wiki

Carme Mythological Legend

Carme was a Cretan demi-goddess, daughter of Euboulos, the demi-god of ploughing and planting of grain seed. She would become the mother of the huntress Britomartis with Zeus.Theoi

Carme Moon Group

Carme is the largest of the group of Jovian moons referred to as the Carme group. They have all been grouped together because it is believed they all shared the same common source. In addition to the supposed common source, all the members of the group are non-spherical and retrograde, that is they all orbit the planet Jupiter in the opposite direction that Jupiter rotates. As they are all retrograde in the group, they all end with the letter "e" as dictated by the International Astronomical Union, the international body that defines the names. Although some names have not yet been agreed upon. Kiddle
