HD 141937 b
HD 141937 b is an extrasolar planet discovered in April 2001[1] with mass of 9.7 times Jupiter. The mass is minimum since the inclination of the orbit is unknown, which will probably be a brown dwarf instead if the true mass is known. 653-day orbit would place the distance one and a half times farther away from the star as Earth is from the Sun with high eccentricity of 41%.
