The Warthog Posted July 3, 2006 Share Posted July 3, 2006 Actually, I knew that Earth was farthest from the Sun in Northern Hemisphere summer, but I didn't realize the date was so close to Midsummer. How much farther from the Sun are we now than in Midwinter? Link to comment Share on other sites More sharing options...
