Siri (minor planet designation: 332 Siri) is a main belt asteroid in orbit around the Sun. It was discovered by German astronomer Max Wolf on 19 March 1892 in Heidelberg.[2] The origin of this asteroid's name is unclear. On October 5, 2092, 332 Siri will pass 4,981,670 km (3,095,470 mi) from the asteroid 29 Amphitrite with a relative velocity of 2.054 kilometers per second.[1]
