HD 12648 and Its Lone Known Planet

HD 12648 is a G-type star 594 light-years away. Its spectral type places it in the same broad temperature class as the Sun, though it is cooler than the Sun at 4840 K. The star is 1.2 solar masses and 9.2 solar radii, both larger than the Sun. Its age is given as 4.5 billion years.

One planet is known to orbit this star. HD 12648 b was discovered in 2015 by the radial velocity method, which detects the wobble a planet's gravity induces in its star. The planet's minimum mass is 623 Earth masses, roughly 1.96 times Jupiter's mass and larger than Earth's, and its orbital period is 134 days.
