(241528) Tubman is an asteroid located in the outer main belt that was discovered by the Wide-Field Infrared Survey Explorer ( IAU code C51) on February 8, 2010, an unmanned space telescope operated by NASA that began operations in January 2010. The asteroid had already been sighted in October 2005 and in 2009 under the provisional designations 2005 UV 359 and 2009 BS 108 .
The mean diameter of the asteroid was calculated to be 7.115 (± 0.453) km, the albedo as 0.042 (± 0.007). So with (241528) Tubman one can assume a very dark surface.
The asteroid is a member of the Schubart family, a group of asteroids that was probably formed by collision 1.7 (± 0.7) billion years ago and orbits the Sun in an orbital resonance of 3: 2 with the planet Jupiter . This group is named after the asteroid (1911) Schubart . The ageless (not osculating ) orbital elements of (241528) Tubman are almost identical with the smaller (when one of the absolute magnitude emanating from 15.6 versus 14.9) asteroid 2015 FF 355 .
(241528) Tubman was named on July 12, 2014 at the suggestion of a team of astrophysicist Carrie Nugent after the escape helper Harriet Tubman (* approx. 1820; † 1913). Tubman helped runaway slaves flee the southern states . A Venus crater on the northern hemisphere of the Venus was named after Harriet Tubman in 1994 : Venus crater Tubman .
