Stephan’s Quintet

Stephan’s Quintet is a group of five galaxies about 300 million light years running a curious dance.
Gravity is making, including and gravitationally, is running a slow dance that spins.

Remember, the problem of the two bodies (gravitational attraction) it is simple, that of the three, very complicated (by differential equations involved, its resolution), so imagine the five.

And while it’s spiral galaxies, seen as many of its stars are getting out of its angular momentum due to the gravitation of other galaxies. Remember that galaxies collide, they destroy gravitationally.

Stephan’s Quintet is in the constellation of Pegasus.
