Summary Images for Known Extrasolar Planets

First set of extrasolar planets

Second set of extrasolar planets

Third set of extrasolar planets

Fourth set of extrasolar planets


Because these images are so large, we have chosen to list them seperately. Viewing all four images will show you all of the known extrasolar planets to date (November 29, 2001). Mercury, Venus, Earth, Mars and Jupiter are listed for reference.

The first thing to note about these images is that there is a mass key on the fourth image. Mass is given in MJ, Mass of Jupiter. So for instance, an extrasolar planet that has a mass of 3.9 MJ is 3.9 times as massive as Jupiter. Jupiter's mass is 1,898x10^24 kilograms, so the extrasolar planet's mass is 3.9 X 1,898x10^24 kilograms. The name of each planet is written in white on that bar. Most planets are simply a derivation of the parent star's name. Eccentricity of the planet's orbit is listed at the end of each bar. And the distance from the parent star can be read by looking at the AU bar at the top and bottom of each image.
