Around 13 times per century, Mercury passes between Earth and the sun in a rare astronomical event known as a planetary transit. Mercury orbits in a plane that is tilted from Earth s orbit, moving above or below our line of sight to the sun. The 2016 Mercury transit occurred on May 9th, between about 7:12 a. m. and 2:42 p. m. EDT. The images in this video are from NASA s Solar Dynamics Observatory, or SDO. Transits provide a great opportunity to study the way planets and stars move in space information tha
