2025年2月15日 · WASP-12 b is a gas giant exoplanet that orbits a F-type star. Its mass is 1.47 Jupiters, it takes 1.1 days to complete one orbit of its star, and is 0.0234 AU from its star. Its discovery was announced in 2008.

WASP-12b is a hot Jupiter [6] (a class of extrasolar planets) orbiting the star WASP-12, discovered in April of 2008, by the SuperWASP planetary transit survey. [7] [1] The planet takes only a little over one Earth day to orbit its star, in contrast …

wasp-12b是气态行星，大约是木星质量的1.5倍，大小是几乎木星的两倍。 该行星在围绕着一颗距地球870光年的恒星旋转。 “超级广角搜寻行星”工程的基地在英国，该工程利用西班牙加那利群岛上的望远镜以及南非的望远镜来扫描天空，搜寻从其恒星前面穿过的远 ...

WASP-12b 是由 SuperWASP 使用 凌日法 於2008年4月1日發現環繞著 WASP-12 的一顆 系外行星 [ 2] 。 由於WASP-12b環繞的軌道非常靠近母恆星，它是已知系外行星中密度最低者之一（因為接受母恆星的輻射能而膨脹）。 該恆星的軌道周期只比一天略長一點，而地球環繞 太陽 一周要365天。 它與母恆星的距離只有 地球 與 太陽 距離的 1 / 44 ， 軌道離心率 則與木星相同。 2013年12月3日，天文學家報告以 哈伯太空望遠鏡 觀測WASP-12b的大氣層時發現了水的存在 [ 6][ …

2024年10月25日 · The doomed planet WASP-12b is a hot Jupiter that orbits so close to its parent star, it's being torn apart. It takes this alien world only 1.1 days to completely circle its sun. The star's scorching heat is slowly stripping away and devouring the planet's atmosphere.

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 ...

The transiting exoplanet WASP-12b is located some 870 light-years from Earth. This extremely irradiated planet orbits its Sun-like, G0 parent star in just over 26 hours, resulting in a dayside temperature of ~2,700 K (4,400 F).

The host star of WASP-12 b is the primary of a hierarchical triple system. The distant binary consists of two M dwarfs. This table lists all stars in the system WASP-12. The following plot shows the approximate sizes of the planets in this system The Solar System planets are shown as …

2024年1月4日 · To date, the hot Jupiter WASP-12 b has been the only planet with confirmed orbital decay. The late F-type host star has been hypothesized to be surrounded by a large structure of circumstellar material evaporated from the planet.
