This is a NASA 'Our World' video clip focusing on the celestial objects that orbit the planets of the solar system. The narrators include an enthusiastic young student and a planetary scientist who provide intriguing information about a variety of moons. The presence of water on some moons raises the possibility that there may be life somewhere else in the solar system. The defining feature of moons (objects that orbit planets) is assumed in the commentary rather than explicitly stated. The NASA eClip is on YouTube and runs for 4 mins 15 secs.
