Sun, Moon, and Coincidences

The solar eclipses we earthlings experience are unique in the solar system.  The sun is about 400 times bigger than the moon, but the sun is also about 400 times further away than the moon.  Consequently, when the two come together in a solar eclipse, they fit together perfectly.

OK, class, raise your hand if you think this is a coincidence…

  1. The fact that only here in the solar system do we have this “coincidence” – despite all the planet-moon configurations present in it – is one of the things mentioned in The Privileged Planet. So is the “coincidence” that here is the only place where a planet with an atmosphere would allow clear observation of such a thing (well, you might exclude Mars, but perhaps the ever-pervasive dust would hurt), and the “coincidence” that without solar eclipses, spectrometry – the study that gives us the most important information about a star and thus the key to understanding so much of the universe and its history – would not be possible from the ground.

    Deano and I would agree that this DVD and another by the same company, Unlocking the Mystery of Life, would be exceedingly worthwhile investments for your whole family. Mr. Richard Ames has often recommended them and they have been used from time to time in places such as our youth camps.
