Artist's depiction of a Neptune-mass exoplanet orbiting the Sun-like star 55 Cancri. The planet, discovered using data from the Hobby-Eberly, Lick Observatory, and Hubble Space Telescopes, is one of four known planets in this system, located just 40 light-years away in the constellation Cancer. This discovery suggests that complex planetary systems similar to our own may be common in the universe.
