32 Exoplanets Discovered By Chilean Telescope

the4thdimension writes "An article on CNN notes that 32 exoplanets have been discovered using a new Chilean telescope. The telescope is capable of detecting movements of 2.1mph (comparable to a slow walking pace). These 32 new planets give the telescope a total of 75 planets it has discovered, out of the 400 discovered using all methods employed by astronomers. This places the HARPS system as the world's foremost exoplanet hunter."

    So let me get this straight: If this thing were observing a star system 50 light years away, that's 4.7x10^14 kilometres ... and this thing can detect relative movements as small as 3.5km/hr?

    Consider me impressed.

      I was reading the summary thinking "surely a telescope's sensitivity should be measured in arcseconds, and the minimum detectable speed should be in arcseconds-per-second rather than miles per hour." Of course they were talking about bodies moving toward and away from us, rather than across our field of vision, so it's a Doppler effect measurement rather than looking at a picture and saying, "hey! That bit moved!"

      It's the instrumentation that really counts. There are lots of old telescopes which just gather dust, because they have no competitive instruments attached to their focal plane. On the other hand, the success of the HARPS spectrograph clearly shows that even with old telescopes one can do great science.

    While that's out of the question, an unmanned nuke-powered probe could possibly survey such a system in one life-time if sufficiently funded.

    That "walking pace" stat could be very impressive if it were given with the proper qualification information.

    For example, if it could detect an object moving at that pace over the course of a year at 1 light year away... I would probably not be as impressed if it could do it from 50 light years in a matter of minutes.

    Right now the ratio between stars to planets in the milky way is about 1 billion to 1.

    That's a ridiculous statistic. By that measure, the ratio between Diet Coke drinkers and humans is 3.5 billion to 1, because my wife and I are the only people in my group of friends who drink the stuff, and there are 7 billion people on the planet.

    And yet somehow the Coca Cola company keeps making it, just for us...

    A better statistic is the ratio of the number of planets discovered and the NUMBER OF STARS SEARCHED FOR PLANETS. As of 2003, this fraction was at least 10%, and given observational limits may prove to be as high as 100% -- it could well be that ALL sunlike stars have planets.

    Clearly the parent poster was commenting that the ratio is currently stars/planets > 1 (more stars than planets) and he was wondering if the ratio would invert stars/planets 1 (more planets than stars). If we continue to find planets at some point we may find that 90% of the stars we CAN see well enough have more than 1 planet and it would be a safe bet at that point to say that there are more planets than stars.

    I don't think he was suggesting that each star could ever have more than a billion planets. Sorry if you were just being sarcastic or trolling and I didn't get it.

    So what would you call a rocky body the size and shape of (say) Earth or Mars that doesn't orbit a star? The IAU's inane mal-definition aside[*], I suspect most people would call it a planet (possibly with the qualifier "rogue" tacked on). I don't think we have much idea how many such bodies exist, but it's not beyond the bounds of reason to think that there's are many, many times as many as there are stars.

    [*] I don't really give a rats ass how they classify Pluto--it's clearly a different type of body, and I'd be happy if they called it a Megacomet instead of a Planet, but the IAU's definition is still idiotic: there's no classification for bodies which don't orbit a primary, just to start with, and we can't tell if exoplanets are planets or not without going there, and most damning of all, they define Mercury as being more like Jupiter than it is like Ceres, which is simply brain-dead.
