30 Arietis Bb

30 Arietis Bb (sometimes abbreviated 30 Ari Bb) is a red dwarf which orbits the F-type main sequence star 30 Arietis Ba, located in a quintuple star system approximately 146 light years away in the constellation Aries. The red dwarf was discovered by on Friday, November 27, 2009 by using precise radial velocity method from echelle spectrograph installed in the in Karl Schwarzschild Observatory. The star had a minimum mass of nearly 10 times that of Jupiter. In 2020, after the inclination of the planetary orbit was measured to be just 4.14+0.96−0.90°, the "planet" was found to fall in the mass range of the red dwarf star.
