Astronomers have identified a new super-Earth exoplanet, designated TOI-1846 b, located approximately 154 light-years from Earth. This planet is about 1.79 times the radius of Earth and has a mass approximately 4.4 times greater. It completes an orbit around its host star every 3.93 days. The equilibrium temperature of TOI-1846 b is estimated to be around 295°C.
The discovery was made using data from NASA's Transiting Exoplanet Survey Satellite (TESS). The host star, TOI-1846, is a red dwarf with a mass about 0.42 times that of the Sun and an effective temperature of 3,568 K. It is estimated to be 7.2 billion years old.
Based on its size and density, scientists suggest that TOI-1846 b is likely a water-rich super-Earth. However, further observations, such as radial velocity measurements, are needed to confirm its composition.
