WHAT IS A TRANSIT OF VENUS?• The planet Venus passes directly between the Sun and Earth

• Tiny Venus tracks across the face of our giant Sun

• Pairs of transits occur every 105.5 years to 121.5 years

• Last transits of Venus:

• June 5, 2012

• June 8, 2004

• Next transits of Venus:

• Dec 10-11, 2117

SOME HISTORY• 1627 - Johannes Kepler became the first person to predict a transit of Venus, by

predicting the 1631 event (not very accurately)

• 1639 – first scientific observation by Jeremiah Horrocks in England using a telescope projecting an image of the Sun onto a piece of paper

• 1761 and 1769 – scientists of the day proposed to use solar parallax to calculate the Astronomical Unit

• 1761 – scientists observed from: Siberia, Norway, Newfoundland, Madagascar & South Africa

• 1769 – scientists observed from: Hudson Bay, Baja California, Tahiti, Norway & from several locations in Russia

• 1874 & 1882 – scientists had accurately calculated the Astronomical Unit – 149.59 M kms
