Trio of Super-Earths Discovered

FiReaNGeL writes "A group of astronomers have now discovered a system of three super-Earths around a rather normal star, which is slightly less massive than our Sun, and is located 42 light-years away towards the southern Doradus and Pictor constellations. 'We have made very precise measurements of the velocity of the star HD 40307 over the last five years, which clearly reveal the presence of three planets.' The planets, having 4.2, 6.7, and 9.4 times the mass of the Earth, orbit the star with periods of 4.3, 9.6, and 20.4 days, respectively. 'The perturbations induced by the planets are really tiny — the mass of the smallest planets is one hundred thousand times smaller than that of the star — and only the high sensitivity of HARPS made it possible to detect them' says co-author François Bouchy, from the Institut d'Astrophysique de Paris, France. Clearly these planets are only the tip of the iceberg."

    So that was why the answer to the ultimate question was 42 - and the ultimate question itself must be something like "Are we alone in the universe, and if not, how many light-years away is the nearest other life?"

    A more accurate description would be "Rocky and not a gas giant".

    I think the point is that in the past we could only detect large gas giants, and now we can see smaller ones.

    If I remember correctly the observed light from a star will wobble due to planets orbit around it. Larger the planet, bigger the wobble, and easier to see. Something like that anyway.

    Oh and they don't actually see them, its is more like they make observations that they exist. They can do calculations to figure out density, but thats about it I think.
