Bezzle Posts: 15043 Incept: 2009-08-02 Banned	(Well, not quite Earth-like -- if it's an iron-core terrestrial world, gravity there will be a bitch. More likely, though, it's a pre-Theia impact proto-Earth analog, a water-world with an ocean thousands of miles deep covered by a super-dense atmosphere. Even if having liquid oceans, their surface layers would be extremely sterile and devoid of nutrients, and hence little life could exist there.) ---------- El Sock-Puppeto exposed and killed by Tickerguy 2011-12-09 07:47:04 Permalink
Weezie Posts: 6070 Incept: 2008-05-19 Caution: Congress at Work	It is thought that the Theia impact helped to actually reduce the size of the Earth, thinning the crust and thus allowing for tectonic plate movement (and, of course, this formed the Moon). It's not impossible to think this could have happened here too, just that the starting and ending product were just larger. Any evidence of a satelite (at a proper distance to help rule out satelite capture) could be useful. ---------- The election is not a way to have a voice in government, but rather an impotent declaration if we prefer ketchup or mustard on our **** sandwich. 2011-12-09 09:38:05 Permalink

All you can detect is a star wobble and its relative distance from the sun. It could be Gas, scarred from impact. I really wish we could see these things. ---------- Last modified: 2011-12-09 10:35:39 by ape_lincoln 2011-12-09 10:34:27 Permalink

The earth definitely became more massive because it acquired the iron core of the impacter. A lot of lighter silicate mantle rock was ejected into orbit, and became the moon. ---------- El Sock-Puppeto exposed and killed by Tickerguy 2011-12-09 17:31:15 Permalink

It could be Gas, scarred from impact. In some cases you can get a diameter, if it passes in front of the star, and some radiation readings, but that leaves you with: R, mass and with a lot of assumptions, temperature. But the temperature is mostly bull**** given we don't know what the reflectivity/albedo of the atmosphere or surface is. A black body radiation model would get Mercury vs. Venus very wrong. That whole diamond planet thing a few months back was pretty hilarious. It is very cool that we are finding lots of little planets though. ---------- 'That government is best which governs not at all' --Thoreau 2011-12-10 16:45:31 Permalink
Ape_lincoln Posts: 764 Incept: 2011-08-04 Ron Paul 2012	I wish for the day we can point some sort of analyser scope and get real reading of these things. The only way to be sure of life on any of these planets would be to point the SETI scopes at it and listen. primitive life is impossible to detect at that distance. But intellegent life would of definately figured out and used radio waves at some point in evolution. ---------- Last modified: 2011-12-11 18:43:32 by ape_lincoln 2011-12-11 18:42:29 Permalink
Poid Posts: 610 Incept: 2010-03-08	Quote: The earth definitely became more massive because it acquired the iron core of the impacter. I have no idea how you can say "definitely" here Bez. Planetary formation theory is entirely up in the air. As an aside, rather than trying to spend trillions defeating "climate change", the only real way of ensuring the survival of our species is to colonise other worlds. So its great that we are looking for earth-like planets, but IMO we need to be putting more resources into working out how to get to those worlds. when i think about how much is wasted on everything from defense to financial scams by govts, instead of used for productive things, it really riles me up. 2011-12-11 19:15:16 Permalink

Even if true, it doesnt mean it is the only possible theory that could describe a big orbiting moon.

Ben Posts: 6223 Incept: 2009-10-09 The Distant, Glorious, Past	What I find most interesting is that as soon as the telescope tech gets to resolution XX, we immediately find planets of that size that were not visible before. It is, therefore, logical to assume that as tech improves, more and more planets of various sizes and classes will be found. It is simply a matter of time before we start to locate many 'M' Class planets with abundant liquid water, appropriate gravity and atmosphere. The only question is how do we get there, and should we go? ---------- "Why are you going to learn French?" "Because I'm going to France," says Joe. "I'm from the future.

Indeed; once we're able to see terrestrial-size moons in orbit around terrestrial-sized planets, the game is on. (The real kicker will be when a telescope capable of such precision is then instructed to auto-scan the heavens, saving humans of the monotonous drudgery to hunting for needles in haystacks.) ---------- El Sock-Puppeto exposed and killed by Tickerguy 2011-12-21 01:31:00 Permalink
Eighty6thebs Posts: 4183 Incept: 2007-06-26 It's contained to sub-prime!	I'm sure you guys recognize we're not able to actually see the planets because they reflect only a tiny amount of light from other stars and we're detecting these planets not because we see them, but because we see the impact their gravity has on the star they orbit. Basically we�re guessing that a planet is there because of what it�s doing to the star. ---------- "Sounds to me like you guys a couple of bookies" - Billy Ray Valentine "No I am not scared, and neither should you be!" - Iraqi Information Minister 2011-12-21 08:28:52 Permalink
