The Sun in true white color. The Sun is the Solar System's star and by far its most massive component. Its large mass (332,900 Earth masses), [75] which comprises 99.86% of all the mass in the Solar System, [76] produces temperatures and densities in its core high enough to sustain nuclear fusion of hydrogen into helium.

The Family Portrait of the Solar System taken by Voyager 1. The Family Portrait, or sometimes Portrait of the Planets, is an image of the Solar System acquired by Voyager 1 on February 14, 1990, from a distance of approximately 6 billion km (40 AU; 3.7 billion mi) from Earth. It features individual frames of six planets and a partial background ...
The Solar System Family Portrait is an image of many of the Solar System's planets and moons acquired by MESSENGER during November 2010 from approximately the orbit of Mercury. The mosaic is intended to be complementary to the Voyager 1 ' s Family Portrait acquired from the outer edge of the Solar System on February 14, 1990.
Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from an unprecedented distance of approximately 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System.
An artist's concept of a planetary system. A planetary system is a set of gravitationally bound non-stellar bodies in or out of orbit around a star or star system.Generally speaking, systems with one or more planets constitute a planetary system, although such systems may also consist of bodies such as dwarf planets, asteroids, natural satellites, meteoroids, comets, planetesimals [1] [2] and ...

Comprehensive overview of the Solar System. The Sun, planets, dwarf planets and moons are at scale for their relative sizes, not for distances. A separate distance scale is at the bottom. Moons are listed near their planets by proximity of their orbits; only the largest moons are shown. Only the largest moons are shown. Date: 29 May 2018 ...
