There are eight planets within the Solar System; planets outside of the solar system are also known as exoplanets. Artist's concept of the potentially habitable exoplanet Kepler-186f. As of 14 February 2025, there are 5,834 confirmed exoplanets in 4,356 planetary systems, with 977 systems having more than one planet. [1]
By 1989, all eight planets have been visited by space probes. [297] Probes have returned samples from comets [298] and asteroids, [299] as well as flown through the Sun's corona [300] and visited two dwarf planets (Pluto and Ceres).
The eight planets of the Solar System with size to scale (up to down, left to right): Saturn, Jupiter, Uranus, Neptune (outer planets), Earth, Venus, Mars, and Mercury (inner planets) A planet is a large, rounded astronomical body that is generally required to be in orbit around a star, stellar remnant, or brown dwarf, and is not one itself.

All eight exoplanets are larger than Earth and are within 1.1 AU of the parent star. Only star apart from the Sun with at least eight planets. [142] A Hill stability test shows that the system is stable. [143] Planet h orbits in the habitable zone.

Of those objects that orbit the Sun directly, the largest eight are the planets (including Earth), with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury.
Euler diagram showing the types of bodies orbiting the Sun. The following is a list of Solar System objects by orbit, ordered by increasing distance from the Sun.Most named objects in this list have a diameter of 500 km or more.
The Solar System consists of the Sun and the other celestial objects gravitationally bound to it: the eight planets, their 165 known moons, nine consensus dwarf planets (including Pluto) and their six known moons, and billions of small bodies. Small bodies include asteroids, Kuiper belt objects, comets, meteoroids and interplanetary dust
A class of extrasolar planets whose characteristics are similar to Jupiter, but that have high surface temperatures because they orbit very close—between approximately 0.015 and 0.5 AU (2.2 × 10 ^ 6 and 74.8 × 10 ^ 6 km)—to their parent stars, whereas Jupiter orbits its parent star (the Sun) at 5.2 AU (780 × 10 ^ 6 km), causing low ...
