TOI-1452 is a star system located in the constellation of Draco. It is a binary pair of dim red dwarf stars separated by only 96 astronomical units (AU). A notable feature of this system is the presence of an exoplanet around one of the stars, designated as TOI-1452 b.[4] The secondary star is often distinguished from the first with the name "TOI-1760".[5]
Properties
TOI-1452 is 99 light-years away from Earth.[2] It is two M4 dwarf stars that were observed by TESS as a priority, since they are on the cool dwarf list, a list of high-priority orange-red and red dwarf stars, that was uploaded to TESS. It is a flare star, with a flare observed by TESS where the star brightened by 5%.[5]
Exoplanet
In 2022, an exoplanet was detected orbiting one of the stars every 11 days. The planet, named TOI-1452b, is a super-Earth and potential ocean world with a mass 4.8 times that of Earth and a radius 1.67 times that of Earth.[4][5]
Observation
The star system is too dim to be seen with small telescopes, with an apparent magnitude of +14.4.[2]
