One Ring Zero This provides a large variation in each song's theme, feel, and over all sound. Some lyrics are more poetic, while others tell stories. For One Ring Zero's 2010 release, "Planets", the band composed thirteen new songs to represent the solar system and beyond. Tracks on the album include "An Introduction To Planets," "Mercury," "Venus," "Earth," "Mars Part I," "Mars Part II," "Jupiter," "63 Moons," "Saturn," "Uranus," "Neptune," "Pluto," and "Exoplanets." The concept was inspired by Gustav Holst's nearly century-old orchestral suite "The Planets." As Hearst and Camp put it, "Seemed like maybe it was time to revisit our solar system
Planetary system for a natural satellite. Indications suggest that the confirmed extrasolar planet WASP-12b also has at least one satellite. Unlike the Solar System, which has orbits that are nearly circular, many of the known planetary systems display much higher orbital eccentricity. An example of such a system is 16 Cygni. The mutual inclination between two planets is the angle between their orbital planes. Many compact systems with multiple close-in planets interior to the equivalent orbit of Venus are expected to have very low mutual inclinations, so the system (at least the close-in part) would be even flatter than the solar system.
