It is said that at the center of every galaxy is a supermassive black hole (the picture below shows a picture towards the center of the Milky Way from the Keck Observatory). By observing the orbits of nearby stars, you can get a crude estimate of the mass of this black hole by assuming the stars have a circular orbit. Consider the star SO-2, which has an orbital period of 16.3 years. Its average distance from the black hole is...

Two planets are separated in space by some distance d, each orbiting around their center of mass in the middle of them. They both have the same mass m = 4.81 × 10^20 kg and are rotating with a constant ω = 1.25 × 10^−10 rad/s. How far apart are they (d)? The answer is 1.6 x 10^10 meters.

their center of mass. The radius of their common orbit is r (their
separation is 2r).
A planetoid of mass m (<< M) happens to move along the
axis of the system (the line perpendicular to the orbital plane

Two identical black holes collide head-on. Each of them has a mass equivalent to 32 solar masses. (The sun has a mass of about 2×10^30 kg.) As the black holes collide, they merge, forming a single, larger black hole and additional gravitational waves that carry momentum out of the system. Before the collision, one black hole is moving with a speed of 52 km/s, while the other one is moving at 66 km/s. After the collision the larger black hole...
