Featured Map for 5 June 2012:
Transit of Venus 2012


The transit of a planet occurs when the planet passes between the viewer and the face of the Sun. Viewed from Earth, only transits of Mercury and Venus are possible. Venus, being relative large and close to Earth, creates a discernable, circular spot on the face of the Sun. These rare events occur in pairs, separated by eight years, with more than a century between one pair and the next. The second in a pair occurs today, starting at 22:09:38 UTC.

Today's Featured Map, created by NASA (not using the Great Circle Mapper), shows when and where today's transit of Venus will be visible.

Global Visibility of the Transit of Venus of 5-6 June 2012

  • Region X – Beginning and end of Transit are visible, but the Sun sets for a short period around maximum transit.
  • Region Y – Beginning and end of Transit are NOT visible, but the Sun rises for a short period around maximum transit.
