HD 41004 B and Its Close-Orbiting Planet

HD 41004 B is a star 136 light-years from Earth. It is an M-type main-sequence dwarf, a small, cool red dwarf, with a spectral type of M2 V. Its mass is 0.84 solar masses, its radius is 1.04 solar radii, and its temperature is 5040 K. The star's reported mass estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's. One planet is known to orbit this host.

That planet, HD 41004 B b, was found in 2003 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. HD 41004 B b has a minimum mass of 5840 Earth masses, a lower bound on its true mass, and an orbital period of 1.33 days. Its minimum mass is larger than Earth's and roughly 18.4 times Jupiter's mass.
