TOI-1291 and Its Jupiter-like Planet
TOI-1291 is a star 1400 light-years away with one known planet in orbit. The host star has a reported mass of 1.2 solar masses and a radius of 1.81 solar radii, both larger than the Sun's corresponding values. Its temperature of 6230 K is hotter than the Sun's.
The planet TOI-1291 b was discovered by transit in 2026. 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-1291 b completes an orbit every 7.16 days.
TOI-1291 b is a Jupiter-like planet, a size class that exceeds 4 times Earth's radius. Its radius of 5.64 Earth radii is larger than Earth's.
