→Gliese 581c compared to Earth:
*Gliese 581c is one of three planets so far discovered in the '''Gliese 581 system''', as opposed to the 9 planets in our solar system.

The planet was discovered by the team of Stephane Udry of the Geneva Observatory in Switzerland using the HARPS instrument on the European Southern Observatory 3.6 meter telescope in La Silla, Chile, and is the smallest extrasolar planet discovered to date. Udry's team employed the radial velocity, technique, in which the size and mass of a planet are determined based on the small perturbations it induces in its parent star’s orbit via gravity.
