1677 Tycho Brahe, provisional designation 1940 RO, is a stony Marian asteroid from the central region of the asteroid belt, approximately 12 kilometers (7.5 miles) in diameter. It was discovered on 6 September 1940, by Finnish astronomer Yrjö Väisälä at Turku Observatory in Southwest Finland.[1] The common stony S-type asteroid has a short rotation period of 3.89 hours.[5] It was later named after Tycho Brahe, one of the fathers of astronomy.[2]
