This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most massive objects, volume, density, and surface gravity, if these values are available.
Some theorists think that without this stabilization against the torques applied by the Sun and planets to Earth's equatorial bulge, the rotational axis might be chaotically unstable, exhibiting large changes over millions of years, as is the case for Mars, though this is disputed. [186] [187]
The following outline is provided as an overview of and topical guide to the planet Earth: Earth – third planet from the Sun , the densest planet in the Solar System , the largest of the Solar System's four terrestrial planets , and the only astronomical object known to harbor life .

Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 AU; 44,000 mi), whereas the most distant planet, Neptune, is 30 AU ...
This is a directory of lists of geological features on planets excepting Earth, moons and asteroids ordered by increasing distance from the Sun. Mercury
Some of these planets orbit multiple stars at the same time. Certain planets are so close to their star that it takes only a handful of days to make one revolution, compared to the Earth which ...
Recent studies indicate a large underground saltwater ocean present on Ganymede, Jupiter’s largest moon, with estimated water volume eight times greater than Earth’s world ocean. [3] The fourth largest of Jupiter’s moons, Europa, while smaller than Earth’s moon, ranks fourth in water volume, estimated to be twice more than on Earth. [2]
