1677 Tycho Brahe, provisional designation 1940 RO, is a stony asteroid from the inner regions of the asteroid belt, about 10 kilometers in diameter. It was discovered by Finnish astronomer Yrjö Väisälä at Turku Observatory on 6 September 1940.[7]
The S-type asteroid is a member of the Eunomia family, a large group of stony asteroids in the main-belt. It orbits the Sun at a distance of 2.3–2.8 AU once every 4 years (1,472 days). Its orbit shows an eccentricity of 0.11 and is tilted by 15 degrees to the plane of the ecliptic. It has a rotation period of 3.89 hours[6] and an albedo of 0.23 and 0.47, according to different publications based on the WISE/NEOWISE mission.[4][5]
It is named for the great Danish-born astronomer Tycho Brahe (1546–1601) an early forerunner and father of modern astronomy. He is known for his unprecedented precise measurements in the pre-telescopic era. Brahe is also honored by the prominent crater Tycho in the southern highlands of the Moon and by the Martian cater Tycho Brahe.[2] The bright supernova, SN 1572, is also known as Tycho's Nova.
