Planets

For my awesome Earth and Space class!!
Saturn days-
If you were on the surface of Saturn, how long would a day last? This has remained a mystery for scientists, because the thick clouds of gas obscure the surface of the planet from direct observation by telescopes or orbiters. Below all those clouds there is a surface that rotates at a constant speed. Since scientists can't directly see the surface, they've taken another approach: listening.

With the help of radio emissions that come from the interior of Saturn, scientists have been able to close in on its rotation period. Charged particles trapped in the interior emit radio waves when they interact with Saturn's magnetic field, at about 100 Kilohertz. It's as if Saturn had its own radio station broadcasting at a certain frequency, and as the magnetic field deep inside the planet rotates it changes the frequency of the station.

Neptune- Wait, not so fast! Here's the problem. Neptune isn't a single solid object like the terrestrial planets, so different parts of the planet rotate at different speeds. This is a process that astronomers call differential rotation. Neptune's equatorial zone takes about 18 hours to complete a rotation -- that's slower than the planet's averate 16.1 hour rotation period. And the polar regions can take just 12 hours to rotate; much more quickly than the average.
