TOI-3235 b is a gas giant exoplanet found 237 light-years away from Earth.[2] It was discovered in 2023 by the transit method.[2] It orbits close to its star, which is a red dwarf and located in the constellation of Centaurus.[3] It is also a potential target for future atmospheric observations.[4]
Characteristics
Mass and radius
TOI-3235 b was discovered by the transit method.[1] The exoplanet's mass is 0.665±0.025 MJ and has a radius of 1.017±0.04 MJ. Its semi-major axis is 0.02709±0.00046 AU and has a temperature of 604±19 Kelvin.[5]
Orbit
TOI-3235 b has a smaller orbit than Mercury. The exoplanet's orbit is 2.6 days, which is similar to the orbital period of Gliese 436 b and has an inclination of 88.14±0.046 degrees.
Host star
The host star of the exoplanet is TOI-3235, a M-type main sequence star (red dwarf) that is not visible to the naked eye from Earth with an apparent magnitude of 14.5.[6] The star has a mass of 0.394±0.003 M☉, a radius of 0.3697±0.0018 R☉ and a temperature of 3388±68 Kelvin.[5] It is located 237 light-years away in the constellation Centaurus.[6]
