1270 Datura (1930 YE) is a S-type main-belt asteroid discovered on December 17, 1930 by George Van Biesbroeck at Yerkes Observatory.[1] This asteroid is believed to result from the collisional destruction of a larger parent body approximately 450,000 years ago.[7] It is named for the Datura plant genus.[8]
