Neptune's large satellite Triton is one of the coolest objects in our solar system. It is so cold that most of Triton's nitrogen is condensed as frost, giving its surface an icy sheen that reflects 70 percent of the sunlight that hits it.

Experts estimate that there are as many as 170 moons orbiting the eight planets of our section of the galaxy. Here's our look at some of the beautiful, bold and essentially unexplained moons of our solar system.

*Triton The Moon of Neptune*   One of more than ten moons that orbit Neptune. Average temperature is 400 degrees below zero! The only moon in our solar system to revolve around its planet the opposite way that the planet revolves...interesting.  # planets # Neptune # Triton

Asteroids, or minor planets, are small and often irregularly shaped celestial bodies. The known majority of them orbit the Sun in the so-called main asteroid belt, between the orbits of the planets Mars and Jupiter.
