Although Mercury orbits the Sun once every 88 Earth days, the three bodies align only about 13 times a century due to the planets’ relative orbital planes. One such ‘Mercury transit’ occurred on 11 November 2019. This short video highlights the rare event as recorded by NASA’s Solar Dynamics Observatory in a variety of ultraviolet light wavelengths. The resulting celestial spectacle demonstrates the vast size differences between the Sun and its nearest-orbiting planet to awesome effect. For NASA, however, the observation is more than just public outreach eye candy: scientists use these events to help understand the gravitational interactions of planets and stars in hopes of discovering planets outside our solar system.
