bet Cnc is a K4 III star 290 light-years from Earth, and it hosts one known planet. The star is 1.85 billion years old, with a mass of 1.7 solar masses and a radius of 47.2 solar radii. Its temperature is 4090 K.
The planet, bet Cnc b, was discovered in 2014 by the radial velocity method, which detects the wobble a planet's gravity induces in its star. Its minimum mass is 2480 Earth masses, or roughly 7.8 times Jupiter's mass, and its orbital period is 605 days. That minimum-mass figure is a lower bound, larger than Earth's, and does not fix the planet's true mass.
