Do Trojan exoplanets exist? | Space

Co-orbiting worlds, also known as Trojans, have not been found yet outside the solar system. That’s a strange thing, a new study suggests, given we see them constantly closer to home.

Our solar system is full of Trojans; the asteroids orbit the sun along the same path as a larger planet (like Jupiter) about 60 degrees ahead of and behind the planet. But it might be that tidal forces alter the orbits of larger worlds, like an exoplanet.
