The extrasolar planet HAT-P-7 was shown to either be polar or have this property.
The extrasolar planet HAT-P-7 was shown to either be polar or have this property. Along with the angle of entry, this property of meteor showers like the Perseids explains their high entry speed. Damocles and a few related high-eccentricity asteroids have this property, making some believe that Damocles is an inactive comet. This property is used as evidence for the captured nature of a satellite. A planet is observed to be undergoing this from Earth when that planet is near opposition. This property is indicated by having an axial inclination greater than 90 degrees. Venus and Uranus have the rotational form of this dynamic. This property contrasts with direct motion. For 10 points, name this motion in the opposite direction from Earth's rotation around the Sun.
