Patterns in Motion
	• All planets orbit in almost the same plane (ecliptic, AKA Zodiac) • Almost all motion is counterclockwise as seen from the north: – All planets orbit in this direction – *Almost* all planets spin in same direction • with axes more-or-less perpendicular to ecliptic – Regular moons (like our own moon) orbit in this direction, too • Planets are regularly spaced – steps increasing as we go outward
