The Sun
Our sun, just one unremarkable star among billions at yet the most important star we yet know about.  Life on this world is only possible because of the sun, and only because we are the perfect distance from her-- not too close, not too far.  We are in what astronomers call the "Goldilocks Zone."   As we look for life beyond our solar system, we look for other planets in the "Goldilocks Zones" of their systems.
