It's the first time astronomers have ever spotted exoplanet Trojans in the wild.
About 370 light years away, in the infant star system PDS-70, astronomers may have just caught an exoplanet pulling itself together on the same orbit as its giant sibling.
We already know that more than one object can share the same orbit; Jupiter has a collection of 120,000 asteroids following its same path around the Sun, for example. Earth has one, too. But although it’s theoretically possible, astronomers have never discovered two whole planets sharing the same orbit around a star before. FULL STORY from Inverse
