DMPP-3 A and Its Orbiting Planet
DMPP-3 A is a K0 V star located 148 light-years away, accompanied by one known planet. The star is 10.9 billion years old and has a mass of 0.87 solar masses, a radius of 0.91 solar radii, and a temperature of 5140 K. Its mass and radius are each smaller than the Sun's, and it is cooler than the Sun.
The planet DMPP-3 A b was discovered in 2019 by the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. It has a minimum mass of 2.67 Earth masses, larger than Earth's, and an orbital period of 5.59 days.
