(27147) Mercedessosa is an asteroid of the outer main belt that was discovered on December 28, 1998 as part of the OCA-DLR Asteroid Survey (ODAS), a project of the OCA (Observatoire de la Côte d'Azur) and the DLR ( German Center for Air - and space travel ), was discovered at the 90 cm Schmidt telescope of the French Observatoire de Calern ( IAU code 910). The asteroid had previously been sighted on July 14th and 16th, 1996 at the La Silla Observatory of the European Southern Observatory in Chile under the provisional designation 1996 NZ ₂ .

The asteroid has a nearly circular orbit around the sun with an eccentricity of 0.0077 . The orbit has even less eccentricity than that of the earth . The mean diameter was calculated to be around five km, and the albedo is 0.134 (± 0.027) similar to that of the earth's moon .

According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel (27147) Mercedessosa divided all investigated asteroids into C, S and V types assigned to the C asteroids .

(27147) Mercedessosa belongs to the Eos family, a group of asteroids, which typically have large semiaxes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago. The ageless (not osculating ) orbital elements of (27147) Mercedessosa are almost identical with those of six smaller (when one of the absolute brightness emanates) asteroid: (161617) 2005 UJ ₅₁₃ , (176040) 2000 SY ₂₂₃ , (196714) 2003 SM ₁₀₂ , (201671) 2003 UZ ₇₀ , (229992) 2000 AW ₂₀₇ and 2015 FF ₃₂₇ .

The asteroid was named on September 9, 2014 after the Argentine singer Mercedes Sosa (1935–2009).
