281 Lucretia is an asteroid belonging to the Flora family in the Main Belt.^[4] It was discovered by Austrian astronomer Johann Palisa on 31 October 1888 in Vienna, and is named after the middle name of Caroline Herschel, one of the first female astronomers.^[6] Light curves of this asteroid show a synodic rotation period of 4.349±0.001 h with an amplitude of 0.3–0.4 magnitude. The spin axis appears nearly perpendicular to the ecliptic.^[4]
