769 Tatjana
769 Tatjana is a minor planet orbiting the Sun. The body was named such after Tatiana Larina, protagonist of Alexander Pushkin's poem "Eugene Onegin".[3] It's possible that the name was suggested by the provisional designation of the asteroid, 1913 TA, but unlike bodies named by Wolf, Knopff and Metcalf in the years 1905–1909, there's no naming pattern to support this.
