K2-33b
K2-33b (also known by its EPIC designation "EPIC 205117205.01") is a very young super-Neptune exoplanet, orbiting the pre-main-sequence star K2-33. It was discovered by NASA's "Kepler" spacecraft on its "Second Light" mission. It is located about 456 light-years (140 parsecs) away from Earth in the constellation of Scorpius. The exoplanet was found by using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured. 

Among known exoplanets, K2-33b is considered extremely young − a mere 9.3 million years old. Only one other exoplanet is younger, with an age of 2 Myr (V830 Tau b).
