Three Planets Racing this Weekend
William Robinson writes "This report asks you to keep your eyes on the skies this weekend, when a rare triple-planetary alignment is going to happen. It promises a stellar show for star-gazers. Scott Young of the Manitoba Museum Planetarium says the planets in question -- Mercury, Venus and Saturn -- are all big enough to be seen without a telescope."
Thing is, the conjunction isn't really all that interesting, scientifically. It's interesting mostly because it's rare, and it's a way to get the vigorously nonscientific to actually watch the planets move across the sky. Go out on two successive nights and you can watch them move relative to each other.
No biggie for your college-educated, Slashdot-reading brain, but a lot of people are bored stiff by science. Turn on Jeopardy some day and watch as the board clears of every category except Science. Not always, but too often.
There's an awful lot of people who don't really get how the planetary orbits work, and probably DO think that they would collide. I bet you know at least some of them. Take them out and show them the conjunction. Take them out on successive nights and describe how we can figure out the heliocentric universe from the observations.
