an·gu·lar momentum

(ăng′gyə-lər)
A quantity used to measure the motion of a body that is moving in a circle. The angular momentum depends on the mass and velocity of the body, and on the radius of the circle that it is moving along. Because the velocity of a body moving in a circle is always changing (since velocity is speed and direction), its angular momentum is also always changing.

However, a different approach [2] called quantum celestial mechanics (QCM) offers the potential ability to predict the existence of additional angular momentum in the planetary system, which could indicate additional planets to be detected or additional mass in the form of rings or spherical shells of mass chunks orbiting the star, such as the Kuiper belt or the Oort Cloud in our Solar System.
A research team led by Ekta Patel from the University of Arizona has come up with a new technique that uses the angular momentum of satellite galaxies to estimate the mass of their host galaxy, a method they say is more reliable and precise than older methods that relied on the satellite galaxies' velocities and positions.
"Tidal forces transport angular momentum from the stellar rotations to the orbits.
The default in planet formation is for worlds to coalesce from a dusty disk of gas around a newborn star's middle, a consequence of the conservation of angular momentum. Furthermore, huge planets close to their parent stars "should" be on circular, equator-aligned orbits due to tidal interactions.
