51828 Ilanramon (

provisional designation 2001 OU39) is a Gefionian asteroid from the central regions of the asteroid belt, approximately 5.5 kilometers in diameter. It was discovered on 20 July 2001, by astronomers of the Near-Earth Asteroid Tracking program at Palomar Observatory in California, United States. The asteroid was named in memory of Israeli astronaut Ilan Ramon, who died in the Space Shuttle Columbia disaster.[9]

Orbit and classification

Ilanramon is a member of the

semi-major axis of 2.77 AU). Its orbit has an eccentricity of 0.13 and an inclination of 9° with respect to the ecliptic.[1]

The asteroid's observation arc begins with a precovery from the Digitized Sky Survey taken at Palomar in May 1990, nearly 11 years prior to the body's official discovery observation.[9]

Physical characteristics

Ilanramon is an assumed C-type asteroid,[6] but its membership to the Gefion family and its relatively high albedo (see below) measured by the Wide-field Infrared Survey Explorer (WISE), indicate that it is likely a stony S-type asteroid.[10]: 23

Diameter and albedo

According to the survey carried out by the

albedo of 0.1899,[4][5] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and consequently calculates a larger diameter of 9.24 kilometers based on an absolute magnitude of 13.9.[6]
