exoplanet: planet outside sol
(http://www2.cnrs.fr/sites/communique/image/photo_exoplanete.jpg)
The big white thing in the middle is the star, a brown dwarf ( very young star ), only 25 times the mass of Jupiter, codename 2M1207, in the Hydræ star group.
The planet ( redish thing ) is 5 times the size of jupiter, seems to be a living hell with an atmosphere at 2000°C.
That's cool :p
I have a link, but in french.
-
That's cool :D Well, actually, it's pretty hot, pity the chances are that I'll be long gone before we get to look closely at any of these planets :(
-
*expects a hecate class to go floating past*
Looks like someone made it with solar cell. The star in the middle is cool though.
How far away is this system?
-
stupidely enough, they don't say, they just say the planet is at 55 au from the star. Which is probably interesting if you have a Phd in astronomy, yeah.

1 au = 1 earth orbit, about 90 million miles, 150 million km.
So it has a large orbit...

Toasty

Might have habitable moons though. Like Europa.
-
The gravity tides on that thing would mean that any moons orbiting too close would be crushed, most likely, further out there is higher possibilities though :D
-
this is several years old. i saw it in scientific american years ago.
-
i saw this in astronomy magazine, there are alot that have been discovered, and photographed. I think my favorite is Sedna, the 10th planet in our own system.
-
Yep, but it still doesn't have enough mass to be effecting the orbit of the outer planets as much as they are being altered, so theres still something more out there.

No, that's not, that's from last september, many have been discovered coz they were proffs they were there, but that's the first real pic.

Just being pedantic but Sedna isn't a planet. Nor is Pluto for that matter.
-
Pick up astronomy, the year in review. and flip i agree, there is something else out there. i launched a certain person who wanted to make fs3 into space, and his ego is now affecting the grav fields in our solar system.....sorry about that.
-
Oh, yeah, btw, what's up with that?
-
nothing, thankfuly

not a planet. too small. it's a kuiper object.

So you're the one who made nemesis. The object that theoretically slings comets into the inner solar system from the oort cloud :p

Sedna is not a planet, but Pluto is. Pluto is the lower limit.

no, i'm sure i've seen it in Sciam (though it may have been discover) but at any rate, a science magazine that had that same pic with that same claim, but it was at least a year ago.

I think if Pluto was discovered today, it wouldn't have be counted as one......
-
I think they decided to count Pluto as a planet coz it had a satellite, iirc. Almost as big as Pluto itself, the satellite, but heh.
-
The reason Pluto is still considered a planet is that it would take too much effort to reclassify it as a planetoid and correct the populace.

We forgive you. ;)

Actually, there's also the bit about it's got enough gravity to round itself out and has an independant orbit of the sun.
