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.
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 ...
Giant planet. The four giant planets of the Solar System: ( top) Jupiter and Saturn ( gas giants) ( bottom) Uranus and Neptune ( ice giants) Shown in order from the Sun and in true color. Sizes are not to scale. A giant planet, sometimes referred to as a jovian planet ( Jove being another name for the Roman god Jupiter ), is a diverse type of ...
Jupiter is the biggest planet in our solar system, according to NASA. The planet is what’s known as a gas giant, which means it doesn’t have a solid surface — though it may have a solid core ...
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 first image compares some of the largest TNOs in terms of size, color and albedo. This is a list of trans-Neptunian objects (TNOs), which are minor planets in the Solar System that orbit the Sun at a greater distance on average than Neptune , that is, their orbit has a semi-major axis greater than 30.1 astronomical units (AU).
a dwarf planet, the third-largest-known trans-Neptunian object. Notable for its two known satellites, rings, and unusually short rotation period (3.9 h). It is the most massive known member of the Haumea collisional family. [28] [29] 136472 Makemake: a dwarf planet, a cubewano, and the fourth-largest known trans-Neptunian object [30] 136199 Eris
The Solar System Portal. The Sun and planets of the Solar System (distances not to scale) The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It was formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.
