The first report of an exoplanet within this range was in 1998 for a planet orbiting around Gliese 876 (15.3 light-years (ly) away), and the latest as of 2024 is one around Struve 2398 A (11.5 ly). The closest exoplanets are those found orbiting the star closest to the Solar System, which is Proxima Centauri 4.25 light-years away
The stars with the most confirmed planets are the Sun (the Solar System's star) and Kepler-90, with 8 confirmed planets each, followed by TRAPPIST-1 with 7 planets. The 1,033 multiplanetary systems are listed below according to the star's distance from Earth. Proxima Centauri, the closest star to the Solar System, has three planets (b, c and d).
One particularly distant body is 90377 Sedna, which was discovered in November 2003.It has an extremely eccentric orbit that takes it to an aphelion of 937 AU. [2] It takes over 10,000 years to orbit, and during the next 50 years it will slowly move closer to the Sun as it comes to perihelion at a distance of 76 AU from the Sun. [3] Sedna is the largest known sednoid, a class of objects that ...
There are roughly 2,000 stars at a distance of up to 50 light-years from the Solar System [4] (64 of them are yellow-orange "G" stars like the Sun [5]). As many as 15% of them could have Earth-sized planets in the habitable zones.
As a reference, the Solar System has eight verified major planets, alongside multiple dwarf planets (the existence of Planet Nine is yet unconfirmed [144]). System with most planets in habitable zone TRAPPIST-1: 7 1 Four planets in this system (d, e, f and g) orbit within the habitable zone. [145] System with most planets in exact orbital ...
Scientists have confirmed that Farfarout is the most distant object in the Solar System — it makes Pluto seem close.
It had been determined that the stars were much farther away than the planets. Saturn: Planet of the Solar System 1619 − 1781 10 AU From Kepler's Third Law, it was finally determined that Saturn is indeed the outermost of the classical planets, and its distance derived. It had only previously been conjectured to be the outermost, due to it ...
A distant minor planet, or distant object, is any minor planet found beyond Jupiter in the outer Solar System that is not commonly thought of as an "asteroid".The umbrella term is used by IAU's Minor Planet Center (MPC), [1] which is responsible for the identification, designation and orbit computation of these objects.
