Wildlife of China are short, furry animals with short, rounded ears and thick fur, but they differ markedly in size, habit and habitat. The sable, a species of marten, is prized for its fine fur, which along with ginseng and deer antler velvet, are known as the "three treasures of Manchuria." The sable is found in Manchuria (also called the Northeast) and Altai region of northern Xinjiang. The beech marten of western China and yellow-throated marten of southern China are closely related to the sable. The Siberian weasel, known locally as the "yellow rat wolf," is the most common weasel in China. It
5026 Martes well-defined rotation period of 4.4243 hours with a brightness amplitude of 0.69 magnitude (). According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, "Martes" measures 8.967 kilometers in diameter and its surface has an albedo of 0.066, which is typical for carbonaceous asteroids. The "Collaborative Asteroid Lightcurve Link", however, assumes a standard albedo for stony asteroids of 0.20 and consequently calculates a much smaller diameter of 4.93 kilometers, due to the higher albedo. This minor planet was named for the two species of the family Mustelidae, the pine marten and beech marten.
