It was discovered by Pelageya Shajn on August 15, 1928, and independently discovered by her colleague Grigory Neujmin, both at Simeiz Observatory in Crimea. The 36-kilometer in diameter, S-type asteroid was the first to be discovered by a female astronomer.[1][2]
The asteroid was given the Latin name of the country of Poland.[2]
