2033 Basilea, provisional designation 1973 CA, is a stony asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 6 February 1973, by astronomer Paul Wild at the Zimmerwald Observatory near Bern, Switzerland.[8] The asteroid was named for the Swiss city of Basel.[2]
Classification and orbit
Basilea orbits the Sun in the inner main-belt at a distance of 2.0–2.5 AU once every 3 years and 4 months (1,212 days). Its orbit has an eccentricity of 0.11 and an inclination of 8° with respect to the ecliptic.[1]
The asteroid was first identified as 1953 DA at Goethe Link Observatory in February 1953, extending the body's observation arc by 20 years prior to its official discovery observation at Zimmerwakd.[8]
