TOI-1777 and Its Super-Earth
TOI-1777 is a star 260 light-years away with a mass of 1.06 solar masses, a radius of 0.984 solar radii, and a temperature of 5860 K. Its reported temperature is hotter than the Sun's. One planet orbits this host.
That planet is TOI-1777.01, classified as a Super-Earth, a size class that reaches 2.5 times Earth's radius. Its radius is 2.25 Earth radii, larger than Earth's. It was discovered in 2024 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Repeated dips help establish orbital periods. TOI-1777.01's orbital period is 14.7 days.
