(5900) Jensen is an asteroid of the main outer belt , which was discovered on October 3, 1986 by the Danish astronomer Poul Jensen at the Brorfelde Observatory ( IAU code 054).
The asteroid belongs to the Gantrisch family . This group of asteroids was previously called the Lixiaohua family until (3330) Gantrisch was assigned to the group, which, with its 35 km diameter, replaced the 20 km large (3556) Lixiaohua as the largest member of this family. Sometimes the old family name is still used. It is an asteroid family with relatively chaotic orbital parameters seen over a long period of time, since large minor planets in the vicinity of the family (or their orbits around the sun , which intersect the orbits of the family members) such as (1) Ceres , (2) Pallas , (4) Vesta , (10) Hygiea , (52) Europa , (511) Davida and (704) Interamnia influence the orbits of family members and the family is therefore within the sphere of influence of several orbital resonances.
(5900) Jensen was named after its discoverer at the suggestion of Karl Augustesen and HJ Fogh Olsen .
