I got myself here a satellite rotating at a large distance around planet X.
Distance from center of planet X = 100,
mass of the satellite = 1 gram (really small),
mass of planet X = 1.0 kg
velocity of my satellite 10 m/sec
and in this oddball universe the gravitational constant = 10**4
So the satellite-planet X system has an angular momentum of 100 * 10 = 1000 m**2/sec
Now suddenly I place a second planet, planet Y, right next to planet X
mass of planet Y = 1 kg
So at this instant, the central gravitational source is now 2.0 kg but distance is still 100 and velocity of satellite is still 10
My question : has the angular momentum of the system increased?
I'd like to use angular momentum conservation to figure the characteristics of a
satellite / planet / planet trajectory. That's where I'm going with this.
