This is a visualization of the location and relative size of current 690 confirmed exoplanet on the night sky, using equatorial coordinates with a rectangular projection. The constellation outlines are shown and some major stars are labeled. Exoplanets relative diameters are represented by the size of the red circles using Earth, Neptune, and Jupiter on the legend for comparison. Only those exoplanets closer than 50 light years are labeled with the name of their star. Click the image for a larger version. A plot with distances relative to Earth is also available here. This is a test plot as part of the Habitable Exoplanet Catalog and final versions with color coded planets in the habitable zone will be available on December, 2011.
