1688 Wilkens, provisional designation 1951 EQ1, is a stony asteroid from the middle region of the asteroid belt, about 16 kilometers in diameter. It was discovered by Argentine astronomer Miguel Itzigsohn at La Plata Observatory in the Province of Buenos Aires on 3 March 1951.[8]
The asteroid orbits the Sun at a distance of 2.0–3.3 AU once every 4 years and 3 months (1,547 days). Its orbit shows an eccentricity of 0.24 and is tilted by 12 degrees to the plane of the ecliptic. It has a rotation period of 7.2 and 7.3 hours, based on light-curve observations made in 2011 and 2014, respectively.[6][7] The S-type asteroid's albedo was determined to be 0.066 by Akari, 0.044 by preliminary NEOWISE results, and 0.10 by the Light-curve Database project based on assumptions.[3][4][5]
The minor planet was named after German astronomer Alexander Wilkens (1881–1968), researcher in many branches of astronomy, most notably celestial mechanics. After having worked for many years in Germany, he trained two generations of celestial mechanicians at the discovering La Plata Observatory before returning to his native country.[2]
