About this world
TOI-1744.01 is a sub-Neptune orbiting TOI-1744, a yellow-white F-type star 373 light-years from Earth. It is about 2.7 times the size of Earth. It completes an orbit every 22.3 days at 0.16 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 598 K (325 °C): far too hot for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2024 by transit with Transiting Exoplanet Survey Satellite (TESS). A planet crosses its star and dims it by a tiny, periodic fraction.
