Astronomers using NASA’s Kepler Space Telescope and its extended K2 mission, as well as the W. M. Keck Observatory on Mauna Kea, Hawaii, have discovered the youngest fully formed exoplanet ever detected. Exoplanets are planets that orbit stars beyond our sun.
The newfound planet, K2-33b, is a little larger than the planet Neptune, and orbits tightly and rapidly around its star every five days. It is only 5 to 10 million years old, making it one of a very few newborn planets found to date.
