Gliese 163 c (/ ˈ ɡ l iː z ə /) or Gl 163 c is a potentially habitable exoplanet, [3] [4] orbiting within the habitable zone of M dwarf star Gliese 163. [5]The parent star is 15.0 parsecs (approximately 49 light-years, or 465 trillion kilometers) from the Sun, in the constellation Dorado.
A G-type main-sequence star (spectral type: G-V), also often, and imprecisely, called a yellow dwarf, or G star, is a main-sequence star (luminosity class V) of spectral type G. Such a star has about 0.9 to 1.1 solar masses and an effective temperature between about 5,300 and 6,000 K (5,000 and 5,700 °C ; 9,100 and 10,000 °F ).
It is highly unlikely that this planet would have formed before its parent pulsar, as the resulting supernova would destroy any nearby planets. It has been proposed that PSR J1719−1438 b is not a planet but a star. Specifically, PSR J1719−1438 b was a yellow dwarf star similar to the Sun in a binary with PSR J1719−1438, a higher-mass star.
HD 69830 (285 G. Puppis) is a yellow dwarf star located 41.0 light-years (12.6 parsecs) away in the constellation of Puppis. In 2005, the Spitzer Space Telescope discovered a narrow ring of warm debris orbiting the star. [10] The debris ring contains substantially more dust than the Solar System's asteroid belt.
OGLE-2005-BLG-390Lb (known sometimes as Hoth by NASA [1]) is a super-Earth ice exoplanet orbiting OGLE-2005-BLG-390L, a star 21,500 ± 3,300 light-years (6,600 ± 1,000 parsecs) from Earth near the center of the Milky Way, making it one of the most distant planets known.
HD 28185 is a single [4] yellow dwarf star similar to the Sun, located 128 light-years away from Earth in the constellation Eridanus. The designation HD 28185 refers to its entry in the Henry Draper catalogue. The star is known to possess two long-period extrasolar planets. [4]
Kepler-1625 is an approximately solar-mass star and yet is 1.7 times larger in diameter. [3] Its effective temperature is around 5,550 K, slightly lower than that of the Sun. [12] [3] These parameters suggest that Kepler-1625 may be a yellow subgiant nearing the end of its life, with an age of approximately 8.7 billion years. [3]
WASP-12 is a magnitude 11 yellow dwarf star located approximately 1347 light-years away [2] in the constellation Auriga. [4] WASP-12 has a mass and radius similar to the Sun and is known for being orbited by a planet that is extremely hot and has a retrograde orbit around WASP-12. WASP-12 forms a triple star system with two red dwarf companions ...
