Orbit and classification Natascha is a non-family asteroid from the main belt's background population. Conversely, the asteroid is also considered a core member of the disputed Astraea family.

Its orbit has an eccentricity of 0.16 and an inclination of 6° with respect to the ecliptic. The asteroid was first observed as at Simeiz Observatory in March 1918. The body's observation arc begins at Heidelberg Observatory in February 1930, or 17 months after its official discovery observation at Simeiz.
