A planet going the wrong way
from Science Alert
All planets move around their stars in the same direction as the star spins — at least that's what we thought. But now ANU astronomer Dr. Daniel Bayliss and his colleagues have found a planet that breaks the mold. Using one of the world's largest telescopes in Chile, astronomers have discovered that planet WASP-17b is moving in the opposite direction to the spin of the star around which it orbits. The discovery throws traditional theories about how planets form around stars into doubt.
