769 Tatjana is aminor planet orbiting theSun. The body was named such afterTatiana Larina, protagonist ofAlexander 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.
