210 Isabella is a large and darkasteroid from the centralasteroid belt, approximately 80 kilometers in diameter. It was discovered inPola byJohann Palisa on 12 November 1879. The origin of the name is unknown. It is orbiting at a distance of2.72 AU from theSun with aneccentricity of 0.12 and aperiod of 4.49 yr. Theorbital plane is inclined at an angle of 5.26° to theplane of the ecliptic.[2]
The asteroid is probably composed of material similar tocarbonaceouschondrites. It is classified as a member of theNemesis family of asteroids.[4] Estimates of the diameter range from 74[3] to 87 km.[2] It is spinning with a period of6.67 h.
