SUMMARY
2009 MS9 is confirmed to have a prograde orbit with an inclination of 68.07923°. Orbits with inclinations greater than 90° are classified as retrograde, while those between 0° and 90° are prograde. This information was sourced from the JPL Small-Body Database Browser. The discussion clarifies misconceptions regarding the visual perception of orbits, emphasizing that inclination is the definitive factor in classification.
PREREQUISITES
