Undergrad Can anyone tell me if 2009 MS9 is prograde or retrograde?

[Edward Barrow]

I'm constructing a theory on the origin of extreme trans-neptunian objects.

Can anyone tell me if 2009 MS9 is prograde or retrograde in its orbit? (and show me where you found this information out). I can't for the life of me find it anywhere.

Thanks.

2009 MS9 is prograde in its orbit. Inclinations greater than 90° describe retrograde orbits, thus, an inclination of between 0° and 90° means the orbiting body has a prograde orbit. 2009 MS9 has an inclination of 68.07923°.

Big thanks Glitch! That makes things so much clearer.

Pan around. It's not hard to find a perspective that makes it look retrograde, but as Glitch said, 68 < 90, so prograde.
