(4538) Vishyanand is a main inner belt asteroid discovered on October 10, 1988 by the Japanese astronomer Kenzō Suzuki in Toyota ( IAU code 881) in Aichi Prefecture . The asteroid had already been sighted: in October 1969 under the provisional designation 1969 TJ and in February 1971 (1971 DH 1 ) at the Crimean Observatory in Nautschnyj and on September 25 and 28, 1984 (1984 SF 2 ) at the Anderson Mesa Station of the Lowell Observatory in Coconino County , Arizona .
Mean distance from the sun ( major semi-axis ), eccentricity and inclination of the orbit plane of the asteroid lie within the respective limit values that are defined for the Nysa group, a group of asteroids named after (44) Nysa (also called Hertha family, according to (135) Hertha ).
(4538) Vishyanand was named on October 8, 2014 after the Indian former world chess champion Viswanathan Anand (* 1969), whose patronymic "Viswanathan" is often abbreviated as "Vishy". According to the dedication text for naming the asteroids, one of Anand's interests is astrophotography . The asteroid (23323) Anand, on the other hand, is named after Vikas Anand (* 1989) from Jericho (New York) , who won a prize at the Intel International Science and Engineering Fair .
