(7855) Tagore is an asteroid in the asteroid belt . It was discovered on October 16, 1977 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld from the University of Leiden while evaluating images of the sky that Tom Gehrels had taken. The pictures were taken as part of the Palomar-Leiden survey , a large-scale survey of the sky with the help of the 120 cm Oschin Schmidt telescope at the Palomar observatory .
The asteroid belongs to the Eunomia family, a group named after (15) Eunomia , to which probably five percent of the asteroids in the main belt belong. According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (7855) Tagore assumed a bright surface, so it could, roughly speaking, be around trade an S asteroid .
(7855) Tagore was named on October 5, 1998 after the Bengali poet Rabindranath Tagore , who was awarded the Nobel Prize for Literature in 1913 . As early as 1976, an impact crater on the southern hemisphere of the planet Mercury was named after him in the Bengali spelling of his name: Mercury crater Thākur .
