In Light of Modern Solar System Theory, Why Do the Orbits of the Planets All Lie in the Same Plane?
All Clouds Rotate, at Least a Little, Due to Gravitational Shearing in the Galaxy’s Disk. and If a Cloud Rotates, It Has Angular Momentum: L ~ Mrv. and...
What causes the differences in orbits when the planet is small in mass compared to the star vs when its mass is similar to that of the star?
What causes the differences in orbits when the planet is small in mass compared to the star vs when its mass is similar to that of the star? … So a more massive object will move less than a less massive object when experiencing the same force, but if the two masses are comparable we expect them to move the same.
Why do rotating discs spin faster?
It is unlikely that such a nebula, or any astrophysical gas collapses with zero angular momentum, thus the gas is probably initially spinning at least slowly. Because of conservation of angular momentum, the cloud spins faster as it contracts.
