Newfound Planet Orbits Backward Planets orbit stars in the same direction that the stars rotate. They all do. Except one. A newfound planet orbits the wrong way, backward compared to the rotation of its host star. Its discoverers think a near-collision may have created the retrograde orbit, as it is called.
Giant new planet orbits wrong way Planet hunters have discovered the biggest new world yet and it is going the wrong way around its home sun. The find is unique and astronomers say the planet must have flipped direction after a near miss with another huge passing body swung it around like a slingshot.
