Re: [guide-user] Position Angle

P. Clay Sherrod Dec 13, 2012

Where are you seeing Position Angle noted for the asteroids?
It can apply to direction of motion, or its position relative to another nearby
object, OR the suspected position of a secondary "moon" object locked
gravitationally to the main minor planet.
For comets, it typically is in reference to the angle of the tail as measured
from the center of the coma.
