orbits of the planets.
The orbits of the planets all lie in nearly the same plane for preservation of angular momentum.
Almost certainly. As the dust and gas fall into the nebula under its gravity, each atom will impart SOME sort of sideways momentum, and the total of all that is almost certainly not zero; there will be some angular momentum.
Our solar system is the planets
Well, they are being attracted to the sun, but orbit fast enough that they don't fall into the Sun.
Each planet (and the Sun) rotates about its own axis. The axis is an imaginary line between the poles of a planet. All points on the planet rotate around this central line. The angular momentum vectors of the Sun and planets together can be added up and the result is an equivalent rotation in a plane called Laplace's invariable plane. The invariable plane lies within about half a degree of the plane of Jupiter's orbit. About 98% of the angular momentum in the Solar System is contributed by the four outer planets. That means that if those planets were collapsed into the Sun it would rotate 50 times faster and throw off a new belt of debris, eventually forming a new solar system. That argument explains why there are so many solar systems.
because the majority of the solar system rotates the same way. conservation of angular momentum.
The Earth condensed out of a rotating Solar Nebula, inheriting its angular momentum for the condensing cloud. The conservation of angular momentum allows the Earth to maintain its orbit.
counter-clockwise. All the the objects in the solar system orbit in that direction and almost all of them rotate in that direction. This due to the conservation of angular momentum.
The orbits of the planets all lie in nearly the same plane for preservation of angular momentum.
It's a demonstration of their angular momentum vectors being aligned in almost the same direction. Laplace added up all the vectors for the planets (the angular momentum vector is directed along the axis of rotation) and defined an invariable plane for the solar system, which is a plane that stays the same all the time. Total angular momentum is conserved so this plane will never change, even though momentum might be exchanged between the planets as their orbits change slightly.
"Down" is the direction of the greatest mass, which, in the Solar System, is the Sun. The reason ALL comets haven't fallen into the Sun is that there also have angular momentum, which results in them falling AROUND the Sun.
The force of gravity is what keeps planets and other objects in orbit around the sun, along with the angular momentum of the planets and objects. Without gravity, they would just fly away into space, and without angular momentum, they would just fall into the sun. But both of those together produce orbital motion.
The solar system condensed out of a cloud of interstellar gas, some four and a half billion years ago. The gas was rotating, and that angular momentum became the various forms of revolution and rotation found in the planets and the sun. Ultimately, if our current understanding of cosmology is correct, the rotation of the original gas cloud can be traced back to the Big Bang. It derives from the original expansion of the universe.
Conservation of rotational momentum around the common center of mass.The gas/dust cloud that formed the solar system was rotating and that momentum is conserved in the orbits of the planets, comets, asteroids, etc.
Almost certainly. As the dust and gas fall into the nebula under its gravity, each atom will impart SOME sort of sideways momentum, and the total of all that is almost certainly not zero; there will be some angular momentum.
1st part - energy from fusion of hydrogen into helium. 2nd part ??? if you mean the fact that it rotates, that momentum was picked up before the solar system was formed it's called angular momentum and came from the primordial gas cloud. Ummmmmmmmmmm.... idk check in google!!
A solar system allows a star to exist in a stable condition by taking most of the angular momentum that arose when the star condensed from a random cloud of gas. Without a solar system the average star would spin much too fast and start to fly apart, forming another solar system.
