2685 MasurskyThe asteroid 2685 Masursky is a main belt asteroid. It was discovered by Edward (Ted) Bowell in 1981. It was named after Harold Masursky (1923–1990), a planetary geologist at the U.S. Geological Survey, Flagstaff, who worked on numerous space missions. Little was known about Masursky until the Cassini space probe, en route to Jupiter and Saturn, flew past it on 23 January, 2000. Since Cassini passed the asteroid at a distance of 1.6 million kilometres (about four times the Earth-Moon distance), the images it returned showed nothing more than a dot. Nevertheless, Cassini was able to determine Masursky's size (about 15–20 km in diametre). Masursky's orbit places it within the Eunomia family, and it had been assumed that like the other members of the family, Masursky would be an S-Type. However, Cassini's observations suggest that it may not be an S-Type; its true composition remains uncertain.
