Exoplanets seem all to have elliptical orbits

  1. May 13, 2009 #1
    exoplanets seem all to have elliptical orbits, and when you look at our solar system the orbits are all nice and defined, how come. And the gaz giants all seem to be star huggers where as in out solar system they are not, any explanations on this difference?

    It could just be that we are more likely to detect distant exoplanets that are closer to their star than our gas giants are.

    Most likely. The types of planets we see in great numbers(massive and close to the host star) are precisely the type of planets you expect to see first with low sensitivity equipment. As we refine our observational techniques, we are beginning to find lower mass planets and planets further away from the host star.

    Exoplanets are very difficult to detect because they don't emit any light of their own and are completely obscured by their extremely bright parent stars - normal telescope observation techniques cannot be used. In order to find exoplanets we use a variety of techniques to detect the effect they have on their stellar system.

    the planets that we have known before are those that can be seen by our naked eye, as time goes by and studies go deeper/ as astronomers refine their observation, we find more. How interesting, isn't it?
