"And that's fundamentally how our solar system is made: This thing called angular momentum, that spinning effect stretches things out into a disc." That's why the planets in the solar system orbit ...

Despite this, the slightly eccentric and tilted orbits of the Solar System’s gas giants ... Conservation of angular momentum shaped their orbits into a flat plane. As planets grew, gravitational ...

with dimensions comparable to the solar system. At first the circumstellar disk is in a phase called an accretion disk, where mass is transported inward toward the star and angular momentum is ...
