The Planet Beta Pictoris B

Caption

This artist's view shows the planet orbiting the young star Beta Pictoris. This exoplanet is the first to have its rotation rate measured. Its eight-hour day corresponds to an equatorial rotation speed of 100,000 kilometers/hour -- much faster than any planet in the Solar System.
