Poles in Space
The areas around the North and South Poles of planets, moons, and even the Sun are often interesting and unusual places. We have discovered all sorts of unique behavior at these locations, while on some planets, the characteristics of the poles are similar to those of Earth. On some planets and moons, we still don't have observations from their poles so can only make educated guesses of what we expect to find there based on our scientific understanding of the celestial body. The links below provide an overview of what we know about the polar regions of many of the major bodies in the solar system. An important concept related to the poles of the planets is the amount of tilt of a planet's rotational
axis relative to the plane of the ecliptic
- the orbital plane in which the planets orbit the Sun. Planets with a large tilt have stronger seasonal behavior than planets without a tilt.
