Fomalhaut was the first stellar system with an extrasolar planet candidate imaged at visible wavelengths, designated Fomalhaut b. However, analyses in 2019 and 2023 of existing and new observations indicate that Fomalhaut b is not a planet, but rather an expanding region of debris from a massive planetesimal collision.

Red dwarf systems. K-type main-sequence star systems. Yellow dwarf systems. F-type main-sequence star systems. v. t. e. The following list includes some of the potentially habitable exoplanets discovered so far. It is mostly based on estimates of habitability by the Habitable Worlds Catalog (HWC), and data from the NASA Exoplanet Archive.
Absolute magnitude is defined as the apparent magnitude that a star or object would have if it were observed from a distance of 10 parsecs (33 light-years; 3.1 × 10 14 kilometres; 1.9 × 10 14 miles). Therefore, it is of greater use in stellar astrophysics since it refers to a property of a star regardless of how close it is to Earth.
www.greenfieldmc.net. Greenfield is a fictional city created in the sandbox video game Minecraft. As of May 2022, the city is one-fourth complete and has a size of 20 million blocks. [2] The city was started by Minecraft user THEJESTR in August 2011. [3][4] As of April 2022, there are approximately 1.3 million downloads of the city map. [5]
The team released a paper of their findings dated 27 April 2007, published in the July 2007 journal Astronomy & Astrophysics. [1] At the time of discovery, it was reported to be the first potentially Earth-like planet in the habitable zone of its star [5] [6] and the smallest-known exoplanet around a main-sequence star, but on 21 April 2009, another planet orbiting Gliese 581, Gliese 581e ...
Quaoar (minor-planet designation: 50000 Quaoar) is a large, ringed dwarf planet in the Kuiper belt, a region of icy planetesimals beyond Neptune.It has an elongated ellipsoidal shape with an average diameter of 1,090 km (680 mi), about half the size of the dwarf planet Pluto.
All exoplanets orbit around star A in the binary system. 47 Ursae Majoris: Ursa Major: 10 h 59 m 27.97 s +40° 25′ 48.9″ 5.10: 46: G0V: 1.029: 5892: 7.434: 3: Planet Taphao Thong was discovered in 1996 and was one of the first exoplanets to be discovered. [47] The planet was the first long-period extrasolar planet discovered. The other ...
30° – 70 °. —. The Gliese 581 planetary system is the gravitationally bound system comprising the star Gliese 581 and the objects that orbit it. The system is known to consist of at least three planets discovered using the radial velocity method, along with a debris disk. The system's notability is due primarily to early exoplanetology ...
