TOI-715 is a red dwarf star located 42 parsecs (140 ly) from the Earth in the constellation Volans[note 1], very close to the southern celestial pole. It hosts one confirmed exoplanet, named TOI-715 b, a super-Earth orbiting in its habitable zone. Another planet in the system is suspected.[3] The star has an apparent magnitude of 16.7 and is too faint to be seen with the naked eye or even a small telescope.[5] It is smaller and cooler than the Sun, with 24% its radius and a temperature of 3,075 K (2,802 °C) (53% solar).[3]
