Planetary System
Planet 83 Leonis Bb was discovered in Jan 2005 by the California and Carnegie Planet Search team, who use the radial velocity method to detect planets. The planet's minimum mass is less than half of the mass of Saturn. It orbits very close to the star, completing one orbit in about 17 days.
In 2010 the second planet 83 Leonis Bc was discovered.

“Whoever places his trust into a system will soon be without a home. While you are building your third story, the two lower ones have already been dismantled.”
