1405 Sibelius, provisional designation 1936 RE, is a stony Florian

Turku Observatory in Southwest Finland.[11] The asteroid was named after composer Jean Sibelius.[2]

Orbit and classification

Sibelius is a member of the Flora family, one of the largest populations of stony asteroids in the entire main-belt. It orbits the Sun in the inner main-belt at a distance of 1.9–2.6 AU once every 3 years and 5 months (1,234 days). Its orbit has an eccentricity of 0.15 and an inclination of 7° with respect to the ecliptic.[1] The body's observation arc begins with an observation taken at Turku two weeks prior to its official discovery observation.[11]

Physical characteristics

Sibelius has been characterized as an S-type asteroid by Pan-STARRS photometric survey.[10]
