Relative masses of the Solar planets. Jupiter at 71% of the total and Saturn at 21% dominate the system. Relative masses of the solid bodies of the Solar System. Earth at 48% and Venus at 39% dominate. Bodies less massive than Pluto are not visible at this scale. Relative masses of the rounded moons of the Solar System.
Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is less massive than Eris.
Jupiter is the fifth planet from the Sun and the largest in the Solar System.It is a gas giant with a mass more than 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun. Jupiter orbits the Sun at a distance of 5.20 AU (778.5 Gm), with an orbital period of 11.86 years.
A dwarf planet is a small planetary-mass object that is in direct orbit around the Sun, massive enough to be gravitationally rounded, but insufficient to achieve orbital dominance like the eight classical planets of the Solar System. The prototypical dwarf planet is Pluto, which for decades was regarded as a planet before the "dwarf" concept ...
The number of dwarf planets in the Solar System is unknown. Estimates have run as high as 200 in the Kuiper belt [1] and over 10,000 in the region beyond. [2] However, consideration of the surprisingly low densities of many large trans-Neptunian objects, as well as spectroscopic analysis of their surfaces, suggests that the number of dwarf planets may be much lower, perhaps only nine among ...
Ceres(minor-planet designation: 1 Ceres) is a dwarf planetin the middle main asteroid beltbetween the orbits of Marsand Jupiter. It was the first known asteroid, discovered on 1 January 1801 by Giuseppe Piazziat Palermo Astronomical Observatoryin Sicily, and announced as a new planet.
Saturn is the sixth planet from the Sun and the second largest in the Solar System, after Jupiter. It is a gas giant , with an average radius of about nine and a half times that of Earth . [ 27 ] [ 28 ] It has an eighth the average density of Earth, but is over 95 times more massive.
A super-Jupiter is a gas giant exoplanet that is more massive than the planet Jupiter. For example, companions at the planet– brown dwarf borderline have been called super-Jupiters, such as around the star Kappa Andromedae. [1] By 2011 there were 180 known super-Jupiters, some hot, some cold. [2] Even though they are more massive than Jupiter ...
