Not a lot going on, so I decided to ask what everyone thought about what would be the first group to detect an Earth-mass planet.
Transiting/non-transiting, habitable/hellish, doesn't matter. Just as long as it's mass is ~ 1 M_earth.

Edit: With the announcement of Gliese 581 e, I think I should refine "~ 1 M_earth" to be any planet whose mass is between 0.9 M_earth to 1.1 M_earth, as stated in a post after this.

Does this count?
Quote :
Thus, our discovery of MOA-2007-BLG-192Lb represents the first discovery of an extrasolar planet with a planetary mass ratio orbiting an extremely low-mass primary that is likely to be a brown dwarf, and with a mass of m = 3.3+4.9−1.6 M (or a 2-σ range of 1.0–18 M)
Sure, the 1 Earth mass case lies at the end of the 2-σ range, but you never know...

I voted for OGLE, and MOA-2007-BLG-192Lb helps support my thought.

Haha, I suppose I should have been more accurate. Razz 1 M_earth as in "We're pretty dang confident it's ~1 +/- 0.1 M_earth". I don't quite understand standard deviation enough to phrase it in that context haha.

An interesting note that CoRoT currently has no votes.

so that planet orbiting MOA-2007-BLG-192Lb; any hints on whether or not it's a terrestrial or gas planet? Smile i like the potential in a 3-5 earth mass planet

The planet is most likely a terrestrial planet.

But do not expect to find there the little green men. With a brown dwarf host the habitable zone is certainly tight (<<0.1 AUs) so it should be as cold as Uranus or Saturn.

Who would be the first to detect an Earth-mass extrasolar planet? As far as methods go, I would say Doppler method.

Earth-mass extrasolar planets are already detectable with today's technology. Maybe not around stars like the Sun, but definitely doable around red dwarfs.

Consider Gliese 581e. The mass (or more precisely, the value of m sin i) is 1.9 Mearth. The star, Gliese 581, has a mass of 324 Mjup. Extrapolating from that point, an Earth-mass exoplanet would be detectable, with today's technology and using the doppler method, around a 170 Mjup star in a 0.03 AU orbit. Finding an Earth-mass exoplanet orbiting a star with a mass of 80 Mjup with the doppler method would be trivial with today's technology.

Once you get in the mass ranges you're talking about, the stellar host is a brown dwarf and is very dim. There is a problem getting radial velocity data from the star with a sufficiently high signal to noise ratio.

I voted CoRoT, I guess because it's had the most luck as far as stuff not around red dwarfs.

Resurrecting this for you-know-why. Wait until true mass is determined or does m sin i suffice?
