Largest And Heaviest Satellite In Solar System

Ganymede orbits around jupiter with a diameter of 5 262 kilometers.

Largest and heaviest satellite in solar system.

The solar system is the gravitationally bound system of the sun and the objects that orbit it either directly or indirectly. Four iau listed dwarf planets are also known to have natural satellites. In the solar system there are six planetary satellite systems containing 205 known natural satellites. The heaviest artificial objects to reach space include space stations various upper stages and discarded space shuttle external tanks.

Between 1994 and 1998 the shuttle mir complex of docked spacecraft was the heaviest artificial object in orbit when docked growing heavier from its start as mir continued to be expanded. If we limit ourselves to planetary satellites th. Spacecraft may change mass over time such as by use of propellant. It has a diameter of 5 268 km 3 273 mi making it 26 larger than the planet mercury by volume although it is only 45 as massive.

It is bigger in size than the smallest planet mercury and would have easily been classified as a planet if it was orbiting the sun. Pluto haumea makemake and eris. Ganymede ˈ ɡ æ n ɪ m iː d a satellite of jupiter jupiter iii is the largest and most massive of the solar system s moons the ninth largest object in the solar system it is the largest without a substantial atmosphere. This is a partial list of solar system objects by size arranged in descending order of mean volumetric radius and divided into several size classes these lists can also be sorted according to an object s mass and for the largest objects volume density and surface gravity insofar as these values are available.

Ganymede ganymede is one of jupiter s 79 known satellites. It is the ninth largest object in the solar system and the largest without a substantial atmosphere. A natural satellite or moon is in the most common usage an astronomical body that orbits a planet or minor planet or sometimes another small solar system body. The solar system s planets and its most likely dwarf planets are known to be orbited by at least 219 natural satellites or moons.

19 of them are large enough to be gravitationally rounded. Ganymede is the largest of jupiter s 79 moons as well as by far the largest moon in the solar system. Several of the largest ones are in hydrostatic equilibrium and would therefore be considered dwarf planets or planets if they. Jupiter is a satellite of our sun and has roughly 2 5 times the mass of all the other known solar system objects which could be considered as satellites put together so my answer would be jupiter.
