(5383) Leavitt is an asteroid of the main outer belt that was discovered on September 29, 1973 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery was made during the 2nd Trojan survey, during which Tom Gehrels surveyed field plates recorded with the 120 cm Oschin Schmidt telescope of the Palomar observatory at the University of Leiden , 13 years after the start of the Palomar-Leiden- Surveys .
The asteroid is a member of the Koronis family, a group of asteroids named after (158) Koronis . The timeless (non- osculating ) orbital elements of (5383) Leavitt are almost identical to those of the smaller, if one assumes the absolute brightness of 14.7 compared to 13.1, asteroids (37129) 2000 VZ 22 .
(5383) Leavitt was named on September 1, 1993 after the American astronomer Henrietta Swan Leavitt (1868-1921), who in 1912 discovered the period-luminosity relationship in Cepheids . As early as 1970 a lunar crater on the southern side of the moon was named after Leavitt: lunar crater Leavitt .
