HD 19994 and Its Planet
HD 19994 is a G0V star located 73.5 light-years away. As a G-type dwarf, it is Sun-like in class. The star has an age of 2.56 billion years, a mass of 1.37 solar masses, a radius of 1.75 solar radii, and a temperature of 6190 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's. One planet orbits this host.
That planet is HD 19994 b, discovered in 2003 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 435 Earth masses, a lower bound on its true mass that is larger than Earth's and roughly 1.37 times Jupiter's mass. HD 19994 b completes one orbit in 466 days.
