HD 1666 and Its Planet
HD 1666 is a star 385 light-years away with a spectral type of F7 V. It is 1.76 billion years old, has 1.5 solar masses and 1.93 solar radii, and a temperature of 6320 K. Its mass, radius, and temperature are all greater than the Sun's. One planet orbits this star.
HD 1666 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 2040 Earth masses, roughly 6.42 times Jupiter's mass and larger than Earth's. It completes an orbit every 270 days.
