7655 Adamries, provisional designation 1991 YM1, is a Nysa asteroid from the inner regions of the asteroid belt, approximately 4 kilometers in diameter. It was discovered on 28 December 1991, by German astronomer Freimut Börngen at Karl Schwarzschild Observatory in Tautenburg, eastern Germany.[7] It was named after mathematician Adam Ries.[2]
Classification and orbit
Adamries is a member of the Nysa family, one of the prominent families of the inner main-belt, named after its namesake 44 Nysa. It orbits the Sun at a distance of 2.1–2.7 AU once every 3 years and 9 months (1,373 days). Its orbit has an eccentricity of 0.14 and an inclination of 4° with respect to the ecliptic.[1] Adamries was first identified as 1977 BW at CrAO/Nauchnyj in 1977, extending the asteroid's observation arc by 15 years prior to its official discovery observation.[7]
Physical characteristics
Adamries has been characterized as a carbonaceous C-type asteroid by Pan-STARRS' photometric survey.[6] It is also an assumed stony S-type asteroid.[3]

Naming
This minor planet was named in honor of famous German mathematician Adam Ries (1492–1559), who wrote the first German arithmetic book in the 16th century, explaining in simple terms to the common people how to do arithmetic.[2]
At the time, this was considered to be difficult. This minor planet was the
