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, about 466 ly (143 pc) away from Earth. 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.

Confirmed exoplanet

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. 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).
