5026 Martes 0.24 and an inclination of 4° with respect to the ecliptic. A first precovery was taken at Palomar Observatory in 1953, extending the body's observation arc by 34 years prior to its official discovery observation at Klet. "Martes" has been characterized as a carbonaceous C-type asteroid by PanSTARRS photometric survey. "Martes" forms an asteroid pair with , and was part of the 35 sample asteroid pairs in Petr Pravec's study "Formation of asteroid pairs by rotational fission", published in the journal "Nature". Between 2008 and 2010, several rotational lightcurves of "Martes" were obtained from photometric observations. Lightcurve analysis gave a
