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).
The closest system is Alpha Centauri, with Proxima Centauri as the closest star in that system, at 4.2465 light-years from Earth. The brightest, most massive and most luminous object among those 131 is Sirius A , which is also the brightest star in Earth's night sky ; its white dwarf companion Sirius B is the hottest object among them.
A multiple star system consists of two or more stars that appear from Earth to be close to one another in the sky. [dubious – discuss] This may result from the stars actually being physically close and gravitationally bound to each other, in which case it is a physical multiple star, or this closeness may be merely apparent, in which case it is an optical multiple star [a] Physical multiple ...
A multi-star system consists of two or more gravitationally bound stars that orbit each other. The simplest and most common multi-star system is a binary star, but systems of three or more stars exist. For reasons of orbital stability, such multi-star systems are often organized into hierarchical sets of binary stars. [116]
Also the tenth-nearest star system to our Solar System. Has one confirmed exoplanet: 61 Cygni: A 11.404: K5V [60] ... The Sun is the closest G-type star to the Earth ...
EBLM J0555-57Ab — is one of the smallest stars ever discovered. GY Andromedae — chemically peculiar variable star; MACS J1149 Lensed Star 1 (or Icarus) — second most distant star, 9 billion light years away. [1] [2] P Cygni — suddenly brightened in the 17th century; WNC4 — Messier Object 40; Zeta Boötis — speckle binary test system
The η Carinae star system is currently one of the most massive stars that can be studied in great detail. Until recently η Carinae was thought to be the most massive single star, but the system's binary nature was proposed by the Brazilian astronomer Augusto Damineli in 1996 [9] and confirmed in 2005.
