Mercury Behind the Sun

19-31 August

19 to 31 August

   Today the innermost planet Mercury reaches the point along its orbit around the Sun where it is on the opposite side of the Sun from the Earth. This position is referred to as superior conjunction and all solar system objects orbiting the Sun will, at some point in their respective orbit, reach superior conjunction.

   Each frame of this animated graphic shows the planet Mercury at one-day intervals as the planet moves behind the Sun. We see Mercury from this perspective rather than as it is shown in the banner graphic at the top of the page. This is because the Earth and the other 7 planets all orbit the Sun on pretty much the same plane, or level.
