(249516) Aretha is a major outer belt asteroid discovered on February 15, 2010 by the Wide-Field Infrared Survey Explorer ( IAU code C51), an unmanned space telescope operated by NASA that began operations in January 2010.
The asteroid belongs to the Veritas family, a group of asteroids named after (490) Veritas and probably formed 8.3 (± 0.5) million years ago when an asteroid with a diameter of 150 km broke apart. The timeless (not osculating ) orbital elements of (249516) Aretha are almost identical to those of twelve other asteroids, one of which (13537) 1991 SG is the largest, if one of the absolute brightness emanates.
(249516) Aretha was born on July 12, 2014 after the Soul - singer Aretha Franklin named (1942-2018). The nomination came from Amy Mainzer , who is the Principal Investigator of the NEOWISE project. The Franklin lunar crater, on the other hand, was named after Benjamin Franklin in 1935 .
