Venus Transit – June 5, 2012

On Tuesday June 5, 2012, Venus will transit the sun for the last time this century. The next Venus transit will occur on December 10, 2117, more than 100 years from now. Although Venus transits have occurred for millennia, they have only been observed six times before in recorded history.

Never look directly at the sun. However, the transit can be observed with properly approved eye protection (e.g., mylar glasses), or by using a projected image of the sun (see photo).

Image of the sun projected through a pair of binoculars. It is safe to look at the image on the white card.

However, this method requires adult supervision – NEVER look through the binoculars at the sun.

ADDENDUM (From RASC): The PowerPoint Presentation shared by Ron Macnaughton is excellent!

 

Transit of Venus

by Ron Macnaughton, Chair, Education Committee

A PowerPoint talk on the transit of Venus is posted here. If any Centre wishes to show this half-hour presentation feel free. It talks about:

  • rarity of transits with tilted orbits
  • why the start time in Vancouver is 3 minutes later than St John’s
  • different durations of transit from north and south, how distance to Venus found
  • history of transit observations, especially the 1769 expeditions to Tahiti and Churchill
  • equipment used then to observe transit – Gregorian telescopes and heliostats
  • how transits are used to detect exoplanets


Transit times can be found here:

    Nice site.
    We are enjoying the transit of Venus with our Orion scope near Gaylord Minnesota.
