    Best discussion of this I've seen:

    http://www.anthonares.net/2006/01/published-research-synopsis-55-earth.html [Broken]

    includes an interesting graph plotting mass/distance date on exoplanets found so far

    and the beautiful lensing light curve that this discovery is based on

    the arxiv preprint of the technical journal article is also available:

    Well, I wouldn't call it 'Earth-like', except that it is 'small' compared to Jupiter, Saturn, and the majority of exosolar planets yet discovered.

    It has a mass 5-5.5 times that of Earth, it orbits a red dwarf (smaller and cooler than the sun), and its period about that parent star is 10 years! Not quite Earth-like, IMO.

    Another story link - http://www.stuff.co.nz/stuff/0,2106,3551543a10,00.html [Broken]

    from the BBC on-line article. Definitely not earth-like.

    Astronuc, I think what they mean is, that it’s the most Earth-like planet so far discovered. And going by the criteria of what constitutes an Earth-like planet, it may be the closest approximation we have for some time, now the TPF has been http://www.spaceref.com/news/viewnews.html?id=1092"

    How do they know it has a solid surface? It could be a smaller gaseous planet like Uranus or Neptune.

    How would gravity on this planet's surface compare to earth's
