Planets! Planets! and MORE Planets!

Lookie what I found (ok, what I got in email from niall_shapero.)

Exoplanets, also known as "extrasolar planets", are planets outside our solar system, orbiting distant stars. To keep track of this fast-changing field, the Planetary Society presents this list of exoplanets.

Actually they've also included Mercury through Neptune, for comparison. There are some WEIRD planets out there, witness CoRoT-Exo-7b located about 0.017 AU from its primary with an orbital period of less than a terrestrial day (this is technically known as "Wheeeeeee....") You can sort on all sorts of keys. Oh, just go to the site and have fun!

That is cool lol I am too tired am to play with it but will do so for sure.

Very interesting. I wonder if and when they'll have a list of potentially Earth-like exoplanets, and some idea of what it would take to get there, aside from Gene Roddneberry's favourite pipe-dream.

That is going to require a new method of detection - what we do now is note the effect of really massive superjovians on the movement of the star, or dimming and brightening of the stellar disk by transit of smaller planets across the face. Or even spot the disk itself transiting if the star is close enough. Note that the smallest exoplanet of the list, CoRoT-Exo-7b is still an order of magnitude more massive than Earth. Judging by its location, I suspect it's a jovian or superjovian that had the gas blown off by stellar wind.

I do rather suspect we'll be able to figure out where the choice real estate is considerably before we figure out how to get there... but I'd not bet against either.

NASA is on the case. Kepler launched last Friday.

Yay, Kepler!

I'd heard of it, but no specifics. Looks like a specialized version of the next step from the Hubble - get the thing away from Earth though still in our orbit. Yeah, that SHOULD give us a lot more data.

Pause to imagine what it'll be like when we can park something out along the outer regions of the Solar System...

I think we're STILL getting signals from the Voyagers, so it's not far off.
