The discovery of Phobos is the seventh asteroid discovered by British astronomer john russell Sinde in August 1847, and it is also the first asteroid discovered by him.

His name is Iriz, the incarnation of the rainbow in Greek mythology and the messenger of the gods. Represents the rainbow goddess in Greek mythology, translated into rainbow star in Chinese.

Characteristic photometric observation shows that Phobos is angular in shape, and its off-axis inclination angle is about 85 (the error is about10), so the two hemispheres of celestial bodies are exposed to sunlight or at night for a long time, which will cause great temperature difference for celestial bodies without atmosphere.

The albedo of Phobos surface is not uniform, and there may be bright areas in the northern hemisphere. Generally speaking, the albedo of Hong Shen is higher than that of other asteroids, so it may be composed of a mixture of iron, nickel, magnesium silicate and iron silicate. Its spectrum is similar to that of L and LL chondrites weathered by solar wind, so it may be the main source of this kind of meteorites.

Two observations at/kloc-0 on May 26th, 1995 and/kloc-0 on July 25th, 1997 showed that the diameter of the star was about 200 kilometers.
