Rare Transit Of Mercury Across The Sun
Published 1st April 2019
Mercury transits occur just 13 times per century, on average. They're so rare because the innermost planet's orbit is inclined by about 7 degrees compared to that of Earth, so Mercury, the sun and our home planet just don't line up all that often.
Mark your calendar!
Mercury will cross the sun's face from Earth's perspective on Monday (November11, 2019) in the first such "transit" since 2016.
The next one won't occur until Nov. 13, 2032. This is an unusual event, not to be missed.
The rare transit begins at 12:35 UT (7:35 am EST) and lasts for almost six hours. Mercury's tiny disk—jet black and perfectly round—will glide slowly across the face of the sun.
People in every continent except Australia can see at least a portion of the crossing. In the USA, the best place to be is on the Atlantic coast, where the entire transit is visible. On the Pacific coast the transit will already be in progress at sunrise.
Warning! Mercury covers only a tiny fraction of the sun's surface, so staring at the sun remains just as painful and dangerous as ever. But with a proper filter, the Transit of Mercury can be a marvelous experience.
