Earth and her *3* moons?!?

[furtech]

While looking up an unrelated topic, I came across an interesting event that I hadn't heard about: Earth's third moon.

*THREE* moons??? Well, actually no. Not even two, really. But Earth does have an extra "faux" moon, named "Cruithne" (thanks a LOT for a name only Celts can pronounce!) was discovered by European astronomers in 1986. Technically, it's not really a satellite of Earth, but an asteroid that shares its unusual horseshoe-shaped orbit with the Earth and the sun.

The "third" satellite was discovered in late 2002 by amateur astronomer Bill Yeung in a backyard observatory in Arizona. Astronomy is one of the few areas left where serious amateurs have a chance against huge operations to make major discoveries (with an infrastructure that protects and encourages such discoveries!). Read the article...it's fascinating!

I'm still a science geek at heart...I -love- to hear about things like this. Even when they turn out to be less-than-spectacular, it's great to speculate and just plain -think-! I'm still pretty jazzed: that we can actually re-capture something everyone had pretty much forgotten about thirty years later...I'd really love to see what the thing looks like now (especially considering the materials tests that NASA did in the 80's).

Wow-- I didn't hear about the supernova discovery either! I need to subscribe to something...is "Science News" still being published?
