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
Solar System moons. The centaurs and many short-period comets also orbit in this region. Due to their greater distance from the Sun, the solid objects in the outer Solar System contain a higher proportion of volatiles, such as water, ammonia, and methane than those of the inner Solar System because the lower temperatures allow these compounds to remain solid. The four outer planets, or giant planets (sometimes called Jovian planets), collectively make up 99% of the mass known to orbit the Sun. Jupiter and Saturn are together more than 400 times the mass of Earth and consist overwhelmingly of hydrogen and helium.
