Extrasolar Planets
Collingwood Astronomy Club

A plot of the masses/periods of the first 150 or so extrasolar planets to be discovered. The solar planets have been added for comparison. Current detection techniques are still some way from finding a planet of earth-like mass in an earth-like orbit.

Exoplanet data from the Extrasolar Planets Encyclopedia. This Encyclopedia excludes most objects with masses above 13 times that of Jupiter as these objects might be Brown Dwarves rather than planets.
