WASP-17b is thought to have a retrograde orbit ( with a sky-projected gravitational slingshot resulting from a near-collision with another planet, or the intervention of a smaller planet-like body working to gradually change WASP-17b's orbit by tilting it via the Kozai mechanism.

Thus, when meteoroids meet Earth's atmosphere head-on ( which only occurs when meteors are in a retrograde orbit such as the Eta Aquarids, which are associated with the retrograde Halley's Comet ), the combined speed may reach about 71 kilometers per second.
