BD+03 2562 b: A Giant Planet Around a Distant Star

BD+03 2562 is a star located 3490 light-years away, and one planet orbits it: BD+03 2562 b. The host star is 5.2 billion years old, holds 1.14 solar masses, and spans 32.4 solar radii, making its reported radius estimate larger than the Sun's. Its temperature of 4100 K is cooler than the Sun's.

BD+03 2562 b was discovered in 2017 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion, with repeated wobbles revealing the planet and its orbital period. The planet has a minimum mass of 2030 Earth masses, meaning its true mass is at least this value, and it completes an orbit every 482 days.

That minimum mass is larger than Earth's and roughly 6.4 times Jupiter's mass. Because minimum mass is a lower bound rather than an ordinary estimate, the planet's true mass may be higher.
