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.

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. Spacecraft may change mass over time such as by use of propellant. The solar system s planets and its most likely dwarf planets are known to be orbited by at least 219 natural satellites or moons. Pluto haumea makemake and eris.

Ganymede is the largest of jupiter s 79 moons as well as by far the largest moon in the solar system. Of the objects that orbit the sun directly the largest are the eight planets with the remainder being smaller objects the dwarf planets and small solar system bodies of the objects that orbit the sun indirectly the moons two are larger than the smallest planet. 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. Ganymede ganymede is one of jupiter s 79 known satellites.

19 of them are large enough to be gravitationally rounded. In the solar system there are six planetary satellite systems containing 205 known natural satellites. Several of the largest ones are in hydrostatic equilibrium and would therefore be considered dwarf planets or planets if they. 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.

The solar system is the gravitationally bound system of the sun and the objects that orbit it either directly or indirectly. 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. Of these all are covered by a crust of ice except for earth s moon and io. 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.

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. If we limit ourselves to planetary satellites th. It is the ninth largest object in the solar system and the largest without a substantial atmosphere. Four iau listed dwarf planets are also known to have natural satellites.
