WASP-69, given the formal name Wouri<\/a> by the International Astronomical Union in 2019, is a K-type star somewhat like our Sun but slightly smaller. The planet with the tail, however, is much different from anything in our own solar system.<\/p>\n

That\u2019s because WASP-69 b, named Makomb\u00e9 in 2019 to match its host star (Wouri and Makomb\u00e9 are both rivers in Cameroon), is a hot Jupiter. This class of planet is defined by two major factors: its size similarity to our own gas giant planets and its close-in orbit around its host star.<\/p>\n

WASP-69 b certainly fits the bill: It is about 10 percent bigger than Jupiter \u2014 though only 30 percent its mass \u2014 and orbits its star at a distance just less than five percent the distance at which the Earth orbits the Sun. This means the exoplanet is constantly scorched by stellar radiation to a degree that would make even Mercury sweat.<\/p>\n

WASP-69 b was the subject of considerable attention in the summer of 2022 when it became one of the first targets of the James Webb Space Telescope<\/a> (JWST).<\/p>\n

In new research published Jan. 9\u00a0in The Astrophysical Journal<\/a><\/em>, a team led by astrophysicists at UCLA has revealed the planet\u2019s atmosphere is escaping into space, creating a cometlike tail that stretches at least 350,000 miles (563,270 km).<\/p>\n<\/div>\n
