Planetary system
On January 11, 2007, the California and Carnegie Planet Search team found one planet orbiting HD 75898. It wasn’t published until May 27, 2007. The centre of mass of the system is accelerating, indicating there is a third, more distant, component at least the size of Jupiter. If it has 1 to 13 times the mass of Jupiter it is 30-65 au distant with an orbital period of 4.5 to 460 years. If it is a brown dwarf, it has 13 to 83 times the mass of Jupiter and would be 75-170 au distant with an orbital period of 418 to 1900 years.
