Three Jupiter-sized exoplanets discovered oribiting sun-like stars

Astronomers confirmed the existence of three exoplanets TOI-1820 b, TOI-2025 b, and TOI-2158 b. Their method also uncovered their masses, which gives scientists a better idea about their density and structure. All three are similar in size to Jupiter and orbit their stars on very tight orbits.
