24988 Alainmilsztajn, provisional designation 1998 MM2, is an asteroid from the inner regions of the asteroid belt, about 3 kilometers in diameter. It was discovered on 19 June 1998, by the OCA-DLR Asteroid Survey at CERGA, Caussols, in southeastern France.[5]
The S-type asteroid orbits the Sun at a distance of 2.1–2.7 AU once every 3 years and 9 months (1,364 days). Its orbit shows an eccentricity of 0.14 and is tilted by 5 degrees to the plane of the ecliptic. Light-curve analysis rendered a rotation period of 2.85 hours at the Palomar Transient Factory survey in 2014,[4] and the Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.20 for the body's stony surface.[3]
The minor planet was named after Alain Milsztajn (1955–2007), who was a French particle physicist and astronomer studying the structure of the proton and searched for Galactic Dark Matter using gravitational lensing.[2]
