OverviewEtymology and nomenclatureObservationStellar systemPlanetary systemView from this systemFuture explorationHistorical distance estimates

Alpha Centauri (α Centauri, α Cen, or Alpha Cen) is a triple star system in the southern constellation of Centaurus. It consists of three stars: Rigil Kentaurus (α Centauri A), Toliman (α Centauri B), and Proxima Centauri (α Centauri C). Proxima Centauri is the closest star to the Sun at 4.2465 light-years (1.3020 pc). α Centauri A and B are Sun-like stars (class G and K, respectively) that togethe

How Far is the Closest Star?

The simple answer is that the Sun is the closest star to Earth, about 93 million miles away. But that might not answer your question. Outside of our Sun, our system''s nearest neighbor is Alpha Centauri. This isn''t a single star, it''s actually a triple-star system — three stars bound together by gravity.

Our Nearest Sun-Like Star Has 2 Planets That Might Be Habitable

New evidence has revealed that the closest Sun-like star outside our solar system is orbited by four approximately Earth-sized exoplanets, and researchers think that two of these worlds might be habitable.

SOL 4.7 Solar System

SOL 4.7 -- our SOlar system; Key concepts include: Our solar system is made up of eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn Mercury is closest to the sun and is a small, heavily cratered planet. Mercury looks like our moon. Since Pluto''s reclassification from planet to dwarf planet, Mercury is now the smallest planet

Planet Sizes and Locations in Our Solar System

Mercury is the smallest planet in our solar system. Mercury is a little more than one-third the width of Earth, and has an equatorial diameter of about 3,032 miles (4,880 kilometers). Mercury is the closest planet to the Sun, orbiting at an average distance of 36 million miles (58 million kilometers).

17.3: Overview of Our Planetary System

1 The generic term for a group of planets and other bodies circling a star is planetary system. Ours is called the solar system because our Sun is sometimes called Sol. Strictly speaking, then, there is only one solar system; planets orbiting other stars are in planetary systems. 2 An AU (or astronomical unit) is the distance from Earth to the Sun.

List of potentially habitable exoplanets

This is a list of exoplanets within the circumstellar habitable zone that are either under 10 Earth masses or smaller than 2.5 Earth radii, and thus have a chance of being rocky. [3] [1] Note that inclusion on this list does not guarantee habitability, and in particular the larger planets are more unlikely to have a rocky composition. [4]Earth is included for both comparison and reference

List of multiplanetary systems

Proxima Centauri, the closest star to the Solar System, has three planets (b, c and d). The nearest system with four or more confirmed planets is Gliese 876, with four known. [citation needed] [a] The farthest confirmed multiplanetary system is OGLE-2012-BLG-0026L, at 13,300 light-years (4,100 pc) away. [3]

Proxima Centauri (Alpha Centauri C): Facts, Distance

Proxima Centauri is the closest star to the Solar System and is orbited by the planet Proxima b, which was discovered using the HARPS instrument on the ESO 3.6-metre telescope. Image: ESO, August 24, 2016. (CC BY 4.0) Constellation. Proxima Centauri is located in the constellation of Centaurus. Centaurus is the ninth largest constellation in

List of nearest terrestrial exoplanet candidates

This list of nearest terrestrial exoplanet candidates contains possible terrestrial ("rocky") exoplanets spaced at a distance of up to 50 light-years from the Solar System, ordered by increasing distance. [1] [2] [3]They may be composed primarily of silicate rocks and/or metals.Within the Solar System, the terrestrial planets are the inner planets closest to the Sun.

The smallest and fastest planet, Mercury is the closest planet to the Sun and whips around it every 88 Earth days. The Sun is the heart of our solar system and its gravity is what keeps every planet and particle in orbit. This yellow dwarf star is just one of billions like it across the Milky Way galaxy.

In Depth | Our Solar System – NASA Solar System Exploration

The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed. Nearest to the Sun, only rocky material could withstand the heat when the solar system was young. For this reason, the first four planets – Mercury, Venus, Earth, and Mars – are terrestrial planets.

Our Sun: Facts

The science of studying the Sun and its influence throughout the solar system is called heliophysics. The Latin word for Sun is "sol," which is the main adjective for all things Sun-related: solar. Its nearest stellar neighbor is the Alpha Centauri triple star system: red dwarf star Proxima Centauri is 4.24 light-years away, and
