Neptune's rotational axis (28.3°) is a little more tilted than Earth's (23.5°) and, because it has no solid surface, its equatorial atmosphere spins more slowly (18 hrs.) than its magnetic field (16 hrs.).

With less than nine days to go in its nine-year journey, NASA's New Horizons probe is set to take the first-ever up-close images of the dwarf planet Pluto. And as those images are received on Earth, they are set to air on the Science Channel.
