32496 Deïopites (provisional designation ) is a Jupiter trojan from the Trojan camp, approximately in diameter. It was discovered on 18 November 2000, by astronomers with the LINEAR program at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico, in the United States. The dark Jovian asteroid belongs the 100 largest Jupiter trojans and has a rotation period of 23.3 hours.
Orbit and classification Deïopites is a Jupiter trojan in a 1:1 orbital resonance with Jupiter. It is located in the trailering Trojan camp at the Gas Giant's Lagrangian point, 60° behind its orbit . It is also a non-family asteroid of the Jovian background population. It orbits the Sun at a distance of 4.9–5.7 AU once every 12 years and 1 month (4,419 days; semi-major axis of 5.27 AU). Its orbit has an eccentricity of 0.08 and an inclination of 30° with respect to the ecliptic.
The body's observation arc begins with a precovery published by the Digitized Sky Survey and taken at Palomar Observatory in January 1955, more than 45 years prior to its official discovery observation at Socorro.
Numbering and naming This minor planet was numbered by the Minor Planet Center on 30 November 2001 (). It was named in April 2025 after Deïopites, who was wounded in battle by Odysseus.
Physical characteristics Deïopites is an assumed carbonaceous C-type asteroid. Most Jupiter trojans are D-types, with the remainder being mostly C- and P-type asteroids. It has a typical V–I color index of 0.95 and a BR color of 1.23 (also see table below).
Rotation period In November 2013, a rotational lightcurve of Deïopites was obtained from eleven nights of photometric observations by Robert Stephens at the Center for Solar System Studies in Landers, California. Lightcurve analysis gave a rotation period of hours with a brightness amplitude of 0.19 magnitude ().
Diameter and albedo According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer and the Japanese Akari satellite, Deïopites measures 48.02 and 51.63 kilometers in diameter and its surface has an albedo of 0.070 and 0.080, respectively. The Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous asteroid of 0.057 and calculates a diameter of 50.77 kilometers based on an absolute magnitude of 10.2.
