Transit of Venus


A rare transit of venus is happening on coming wednesday this week. The planet Venus moves across the sun visible as a small dot. Centuries ago this event was observed to calculate the distance earth-sun to be able to calculate for instance the longitude of a ship’s position while navigating on the ocean. The next transit of venus will be in december 2117, so last chance for most of us.
