Ganymede is a Moon that orbits round the planet Jupiter. Its mass is estimated/calculated at being 148,185,846,875,052,000,000,000 kg. Its density has been calculated at being 1.942. Its volume is 76304506998.
The orbital period, i.e. the period it takes to complete an orbit round Jupiter is 7.15455 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 2631km. The value is the radius in km of the said object at the Equator.
The Escape Velocity of the object is 9,869 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 1070.4, which is the furthest point from the centre to the edge of an elliptical point.
The atmospheric gases within the atmosphere of the object are Oxygen.
The equatorial circumference of Ganymede is 16532.3 km. The surface area of Ganymede is 86,999,665.93. The surface gravity of the said item is 1.428. The Mean orbit velocity, that is the speed at which it orbits is 39165.60 km/h. The is the average distance in km of the object is from its parent 1070400.00.
The orbital inclination, the angle at which Ganymede orbits in relation to the orbital plane is 0.18 degrees. The orbital eccentricity is 0.0013, it is the degree at which Ganymede orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
Ganymede is the largest planetary natural moon in . It is bigger than both Mercury and Pluto and would be classed as a planet if it orbited the Sun rather than Jupiter. It is just smaller than Mars, the red planet. Ganymede is even larger than our own Moon.
It was one of the first moons to be discovered orbiting the planet Jupiter. It was discovered by Galileo Galilei who also discovered Io, Europa and Callisto. the moons had originally been named after Roman numerals, I, II, III and IV. Ganymede was given the number III. It was only in the mid-1800 that it got its name Ganymede. Space
Whilst the thin atmosphere contains oxygen, it is not sufficient enough to support human or other animal life forms. The moon is the only moon in the solar system that is known to have a magnetosphere which is usually only seen in planets. It is a cone shaped area around the planet that protects the planet from cosmic and solar radiation. If Earth didn'5t have a magnetosphere then life on Earth would not have taken off and lived this long. NASA
Underneath the surface, it is theorized that there might be a salty water lake. The theory is partly based on a study by the hubble space telescope which looked at the moon's auroras and how they change. The rocking was believed to be caused by the water flowing. Where there's water, could there be life. Its unlikely that there is any life down on Ganymede, the water would be very salty. Some life on earth have been known to survive in extreme environments so its not wise to totally discount it yet.
Ganymede was originally the name of a character in Ancient Greek legend. Ganymede was a young prince who was carried off to heaven by an Eagle. The Eagle was in fact Zeus in disguise. Ganymede was the inspiration for the constellation of Aquarius, the water bearer. Theoi
Galilean Moons are the four largest moons that orbit Jupiter. All four were discovered by Galileo Galilei when he looked up at Jupiter. Galileo is the Italian Astronomer who is credited with inventing the telescope.
