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 12 December 2024, there are 5,806 confirmed exoplanets in 4,336 planetary systems , with 972 systems having more than one planet .

The following is a list of numbered minor planets in ascending numerical order. With the exception of comets, minor planets are all small bodies in the Solar System, including asteroids, distant objects and dwarf planets. The catalog consists of hundreds of pages, each containing 1,000 minor planets.
The Sun, planets, moons and dwarf planets (true color, size to scale, distances not to scale) The following outline is provided as an overview of and topical guide to the Solar System: Solar System – gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the ...
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.
Pluto TV first launched its beta website on March 31, 2014, and was co-founded by chairman and CEO Nick Grouf, Tom Ryan, and Ilya Pozin. [10] [11] Pluto TV was originally developed to provide curated channels of existing online content, offering a slate of nearly 100 categorized channels featuring content aggregated from various video-sharing platforms (including YouTube, Vimeo, and ...
For the giant planets, the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure. [ 11 ] Because Sedna and 2002 MS 4 have no known moons, directly determining their mass is impossible without sending a probe (estimated to be from 1.7x10 21 to 6.1×10 21 kg for Sedna [ 12 ] ).
According to the IAU's explicit count, there are eight planets in the Solar System; four terrestrial planets (Mercury, Venus, Earth, and Mars) and four giant planets, which can be divided further into two gas giants (Jupiter and Saturn) and two ice giants (Uranus and Neptune). When excluding the Sun, the four giant planets account for more than ...
Galaxies, home to stars and planets, come in all shapes and sizes. Witnesses the evolution of galaxies; from clouds of cold gas floating in the voids of space 13 billion years ago to the spirals that fill the night sky.
