1166 Sakuntala is a main belt asteroid orbiting the Sun. Approximately 29 kilometers in diameter, it makes a revolution around the Sun once every 4 years. It completes one rotation once every 6 hours. It was discovered by Praskovjya Georgievna Parchomenko on June 27, 1930. Its provisional designation was 1930 MA.[1]
During a perihelic opposition, when Sakuntala is only 1 AU from the Earth, it can get as bright as apparent magnitude 10.5, as it did on July 7, 2007 and did occur on June 30, 2011 when it will be at magnitude 10.7, being one of the latest discovered asteroids to become so bright to be seen on small telescopes.
