Siberian fur trade to overhunting. Instead of one sable pelt, the following was accepted as its equivalent: one fox, glutton (relative of the marten), or otter pelt; two blue-fox pelts; sixteen polar-fox pelts; or one hundred squirrel pelts. The Russian government decided the amount of other pelts that were equivalent to the sable pelt. Within forty years, almost all Siberian natives were forced into paying fur tribute to the Russians. Russian traders, hunters, and explorers reached the Pacific coastline by 1650 and were collecting fur tribute from most natives along the coast. Beyond the yasuk, the Russians had two principal ways of obtaining
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.
