An asteroid for which there is some possibility of a collision with Earth at a future date and which is above a certain size is classified as a potentially hazardous asteroid (PHA). Specifically, an asteroid is a PHA if its Earth minimum orbital intersection distance (MOID) is <0.05 AU and its absolute magnitude is 22 or brighter. [2]
Šteins is a non-family asteroid from the main belt's background population. [3] [4] It orbits the Sun in the inner asteroid belt at a distance of 2.0–2.7 AU once every 3 years and 8 months (1,327 days; semi-major axis of 2.36 AU). Its orbit has an eccentricity of 0.15 and an inclination of 10° with respect to the ecliptic. [2]
