BD-17 63 and Its Planet
BD-17 63 is a K5 V star 112 light-years away. This spectral type marks it as an orange dwarf, cooler and smaller than the Sun. That is supported by its measurements: a temperature of 4710 K, a mass of 0.74 solar masses, a radius of 0.69 solar radii, and an age of 4.3 billion years.
One planet orbits this star. BD-17 63 b was discovered in 2008 by the radial velocity method, which detects the wobble a planet's gravity induces in its star.
BD-17 63 b has a mass of 1640 Earth masses, roughly 5.16 times Jupiter's mass, and a much larger mass than Earth. It completes one orbit every 656 days.
