Planetary System
On May 4, 2000, the Geneva Extrasolar Planet Search Team announced the discovery of a 3 MJ planet in a 226 day orbit. Three years later on June 30, 2003, the same two teams using the same method discovered a 3.5 MJ second planet orbiting about halfway between the distances of Mars and Jupiter (or in the middle of the asteroid belt) in the solar system from the star.

Famous quotes containing the words planetary and/or system:
“We cannot cheat on DNA. We cannot get round photosynthesis. We cannot say I am not going to give a damn about phytoplankton. All these tiny mechanisms provide the preconditions of our planetary life. To say we do not care is to say in the most literal sense that “we choose death.””
—Barbara Ward (1914–1981)
“Intimately concerned as we are with the system of Europe, it does not follow that we are therefore called upon to mix ourselves on every occasion, with a restless and meddling activity, in the concerns of the nations which surround us.”
—George Canning (1770–1827)
