Jupiter is the fifth planet from the Sun and the largest in the Solar System. It has a mass more than 2.5 times that of all the other planets combined and a diameter 11 times that of Earth.
A comprehensive and updated list of the most massive and smallest objects in the Solar System, sorted by radius and mass. Includes planets, dwarf planets, moons, asteroids, comets, and trans-Neptunian objects, with graphs, notes, and references.
A table of the largest extrasolar objects discovered so far, in terms of physical size, ordered by radius. The list includes planets, brown dwarfs, sub-brown dwarfs, and rogue planets, with their names, radii, masses, and notes.
Learn about the Sun and the objects that orbit it, including the eight planets, the nine dwarf planets, and the small bodies such as asteroids, comets, and moons. Explore the formation, evolution, and features of the Solar System and its place in the Milky Way galaxy.
Neptune is the fourth-largest planet by diameter and the third-most-massive planet in the Solar System. It has no well-defined surface and orbits the Sun once every 164.8 years at an average distance of 30.1 astronomical units.
This web page provides a comprehensive list of Solar System objects by orbit, from the Sun to the Oort cloud. It includes planets, dwarf planets, moons, asteroids, comets, and other small bodies, as well as their names, sizes, and features.
A giant planet, also known as a jovian planet, is a large planet with a thick atmosphere of hydrogen and helium. Learn about the four giant planets in the Solar System, their subtypes, and how they differ from brown dwarfs and ice giants.
The largest planet, Jupiter, is 0.09% the mass of the Sun, while the Earth is about three millionths (0.0003%) of the mass of the Sun. When comparing the planets among themselves, it is often convenient to use the mass of the Earth (M E or M E) as a standard, particularly for the terrestrial planets.
