TOI-2154 and Its Lone Planet

TOI-2154 is a star 967 light-years away with a mass of 1.23 solar masses, a radius of 1.4 solar radii, a temperature of 6280 K, and an age of 2.9 billion years. Its reported mass, radius, and temperature estimates are all larger or hotter than the Sun's corresponding values. One planet orbits this star.

That planet, TOI-2154 b, was discovered by transit in 2023. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness; repeated dips help establish orbital periods. TOI-2154 b completes its orbit in 3.82 days.

The planet's radius is 16.3 Earth radii, which places it among the Jupiter-like class, since such planets exceed 4 times Earth's radius. Its mass is 292 Earth masses. Both its radius and mass estimates are larger than Earth's, and its mean density is 0.373 g/cm³, 0.0677 times Earth's.
