On Board the windjammers we love to lie on the deck at night and search for the Big Dipper..The stars in the Big Dipper are not all at the same distance from Earth and range from 68 light years to 210 light years away from Earth. The three stars in the Dipper's handle are 68, 88 and 210 light years away. Three of the four stars in the Dipper's ladle are 105, 78 and 90 light years away. One light year is equivalent to 6 Trillion miles with light traveling at 186,000 miles per second. The light you see from the Big Dipper has taken anywhere from 63 to 210 years to reach the earth... For a comparison the light from our Sun at 93 million miles away takes 8 minutes to reach the earth...

WOW! It's always nice being able to look up & see all the stars, solar systems, galaxies, etc, at night, especially when there is nothing but sea & sky.
