Earth and her *3* moons?!?
Aug. 23rd, 2005 01:13 pmWhile 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!

And just a couple of months a go was an amateur discovery of a super nova in M51!
New stuff is happening all the time, and the big scopes are all being used for more specific purposes so it'sup to the backyard astronomer to find everything else that goes on :)
