TOI-677 b (or TOI-677b; "TOI" refers to " Tess Object of Interest") is a confirmed "warm" super-Jupiter exoplanet orbiting TOI-677, its host star, in the Ophiuchus constellation, [2] about 466 ly (143 pc) away from Earth. [1] [3] [4] [5] The planet was discovered by NASA's Transiting Exoplanet Survey Satellite (TESS) using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. Discovery of the exoplanet was announced on 13 November 2019. [1] [3] [4] [5]
TOI-677 b is a "warm" super-Jupiter with a temperature of 1,252 K (979 °C; 1,794 °F), and with a mass 1.236 times, and a radius 1.170 times, that of Jupiter. [1] The planet is very close to its bright (V=9.8 mag) main sequence late F host star (based on solar radius, age, temperature and metallicity), TOI-677, and orbits the star once every 11.24 days in an eccentric orbit (e=0.435).
