HD 162020 is an orange dwarf star in Scorpius constellation with a brown dwarf companion.
HD 162020 b.
HD 162020 b is a brown dwarf with mass 15.0 M. The mass is minimum since inclination is not known. This planetar orbits very close to the star at a distance of 0.075 AU. Despite of this, it has an eccentric orbit of 27.7%. The distance from the star ranges from 0.054 to 0.096 AU. It has an extremely high semi-amplitude of 1.813 km/s.
HD 141937 b
HD 141937 b is an extrasolar planet discovered in April 2001 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%.
