TOI-4588: A Distant Star With a Neptune-like Companion
TOI-4588 is a star 734 light-years away with a mass of 1.85 solar masses and a radius of 1.57 solar radii. Its temperature is 7800 K. One planet orbits this host.
That planet, TOI-4588 b, is Neptune-like, meaning its radius falls within the size class that reaches 4 times Earth's radius. It was discovered by transit in 2026, the method in which a planet passing in front of its star from our viewpoint causes a small dip in observed brightness. Repeated dips help establish orbital periods, and this planet's orbital period is 13.1 days. Its radius is 2.93 Earth radii, larger than Earth's.
The star's reported mass estimate is larger than the Sun's, and its reported radius estimate is larger than the Sun's. Its reported temperature is hotter than the Sun's.
