GJ 514 and Its Planet
GJ 514 is an M-type dwarf lying 24.8 light-years away, with a spectral type of M0.5-1.0 V. Its reported mass estimate is 0.51 solar masses, its reported radius estimate is 0.5 solar radii, and its reported temperature is 3730 K, all smaller or cooler than the Sun's corresponding values. Its age is given as a reported lower limit of 0.8 billion years.
One planet orbits this star. GJ 514 b was discovered in 2022 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. The planet has a minimum mass of 5.2 Earth masses, larger than Earth's, and an orbital period of 140 days.
