Exo Planets.

The first exo planets were discovered in 1992 orbiting Pulsar, the remnants of a massive exploded star that became a rapidly rotating neutron star. It took another three years before the first planet orbiting a G-class star similar to our Sun was identified. A gas giant like Jupiter orbits 51-Pegasi every four days. Five years later, several more planets were found near another main sequence star. The exoplanets were not easy to spot, they are tiny, their light is dimmed by the glow of their star, and they are very far away.
