Does the earth have more than one moon???

My college biology professor told the class, among other things, that a new moon for the earth was found about two years ago. So that would make the earth have a grand total of two moons.

It sort of does.

The earth currently only has one permanent moon that we know ow - that would be "the moon".

Apparently fairly often asteroids and other bits of space junk like that get sucked into the earth's gravitational field and will enter into orbit around the earth - sometimes for many thousands of years.

Iyour professor said that it was discovered about two years ago, they were probably talking about the small moon that was "discovered" in 2001 - named 2001 DO47 (<a href="http://groups.yahoo.com/group/Quad-A/message/561">See this link</a>)

Of course, it turned out <a href="http://www.space.com/scienceastronomy/solarsystem/no_asteroid_010301.html">not to be a moon at all</a>.

A google about earth's moons also turned up <a href="http://curious.astro.cornell.edu/question.php?number=578">this link</a> which discusses another asteroid, Cruithne, which some people have called a moon.

Maybe we'll build one down the road.

I got another question...

What is the difference between a moon and a planet? They both look pretty similar. Does it have something to do with it's atmosphere?

I love science, too bad I don't know that much about it.

A moon orbits a planet.

Generally speaking, a planet orbits a star, however, <a href="http://www.space.com/scienceastronomy/solarsystem/planet_confusion_001101-1.html">read this link</a> if you want a more in depth answer.

Have we learned that <a href="http://www.google.com">google</a> is our friend, yet?

TooCute,

Although I am an avid Google user, You seem to it down to a science!! Could you please give some of us amateurs some of your tips on using this great engine? Thanks!!

Sure!

First, you need to open google's website. This works much better if you are using tabs in your browser. Of course, how tabs work will vary by the browser you use.

Open a tab for google.

In the provided box, type in what you would like to search the web for.

Marvel in the information that is on the net.

For increased efficiency, use a browser with built in google.

No, I'm not. It's just that I know there are a lot of knowledgeable science people on the board and I thought I take advantage.

TooCute, you bring up a good point. I'm definately gonna start using google. I don't know why I didn't think of that. Thanks again.

Also, WOW. Even the scientists have trouble answering that question.

I prefer to use the google toobar for IE rather than opening the website. Lots of nifty extra features.

Oh yeah. The Astronomers of the world still debate about Pluto. A few years back there was another movement to de-classify Pluto as a planet.

Definitions get a bit sketchy. Teachnically anything in orbit is a satellite; meaning there are a few hundreds pieces of space gear; gloves, cameras, satellites, satellite parts, pieces of rockets that blew up in orbit, and thousands of smaller pieces of space garbage. Some burns up when their orbit decays, some floats around forever, technically, if the orbit is stable.

Some classify 'natural' and 'artificial' satellites. And also size matters here: The numbers of moons that Jupiter and Saturn have? No one has any real idea.

Whatever number we say it is? Thats just how many our telescopes and spacecraft have found, meaning that they can see. Saturn rings, one could argue, is a zillion moons. Some say amongst all the ring material is a moon that was blasted apart by something, perhaps a laserbeam, as developed by the Dr. Alan Parsons...

I know. That's what's amazing about science. Nothing is ever set in stone.

Yes!!! That Science is NOT set in stone is one of its Hallmarks.

Good science blasts at it's theories; and goes where the results take you, no matter how weird, or absurd, or counter-intuitive. Good Science is self-correcting; it admits its mistakes, in fact uses them as building blocks, and gets better over time.

And now, for those who visit the thread; one of the most terrifying photographs I have ever seen:


http://members.aol.com/miketeachr/earthmoon

The Earth and Moon, as Photographed from the planet Mars, abord Mars Global Surveyor; currently in orbit around Mars. They turned the cameras back, opened up the shutter, and took a snapshot of us. Terrifying. The ultimate in de-provincialization.

I'll let someone much more qualified then me comment, on a similar photograph:

Look again at that dot.
That's here. That's home. That's us.
On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.
The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar", every "supreme leader," every saint and sinner in the history of our species lived there on a mote of dust suspended in a sunbeam.
