(8236) Gainsborough is an asteroid of the central main belt , which was discovered on September 24, 1960 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery came about as part of the Palomar-Leiden survey , during which Tom Gehrels examined field plates recorded at the University of Leiden with the 120 cm Oschin Schmidt telescope of the Palomar observatory .
The asteroid belongs to the Dora family, a group of asteroids named after (668) Dora . The timeless (non- osculating ) orbital elements of (8236) Gainsborough are almost identical to those of the larger, assuming the absolute magnitude of 13.9 versus 14.8, asteroids (5345) Boynton .
(8236) Gainsborough is named after the English painter Thomas Gainsborough , who devoted himself particularly to portrait and landscape painting and, along with William Hogarth and Joshua Reynolds, is considered the most important English painter of the 18th century. It was named on April 2, 1999. As early as 1985, an impact crater on the southern hemisphere of the planet Mercury was named after Thomas Gainsborough: Mercury crater Gainsborough .
