How do planets in the solar system stays in its orbit? Why?

Question

Planets have its own orbit. I am wondering what kind of gravitational forces keeps them in their paths. Maybe this forces or theory are being used by aliens to fly their space ships with less fuel consumption and even travelling to other stars or outside the galaxy. Even Albert Einstein never come to this thought on how this things happened. Maybe, I need another Einstein to answer my question.

Answer 1

time and space are distorted near a massive object like the sun. like putting a bowling ball on a trampoline and then rolling a marble around it except there is no friction in space so it wont slow down and fall towards the bowling ball so it just goes around in circles just like the planets go around the sun.

Answer 2

Newton tried to explain why there is a force of Gravity between the Earth and the Sun. He never really explained why things move or what is the mechanism causing gravity.
Eintein later superceded Newton's theory indicating that it needed refinement. He implied that the centrifugal gravity force was ficticious.And that gravity is really a distortion (bending of space) of Space time. He formulated the field equations which shows that Gravity is the results of the curvature of Space.

In reality all motion in the Universe is continuous in the Universe. Large masses such as planet in the solar system all revolve relative to the dynamic barry center of the Sun all at the same time. The reason is that the Gravity energy relative to the Sun equals the kinetic energy of the earth which acts tangent to its elliptical orbit.
So for a planet to stay in orbit relative to the sun,its orbital kinetic energy must equal to the relative gravity energy that exists beween the Earth and the Sun.

Your inquiry about the Usage of the gravity phenomena by aliens to travel to the Outskirt of the Unverse is interesting. However; Scientifically, cosmologist have never been visually able to observe a space alien.
Perhaps ,what you call space alien is really a Spirit being ,that may not be necessarily subject to the laws of gravity.

Answer 3

Orbits are maintained because of a balance of two things:
1. The object is constantly falling toward an object of greater gravity. For a planet, this is the sun. For a moon or satellite, this is the planet.

2. The object is traveling so fast perpendicular to the force of gravity that it moves away as fast as it falls.

Imagine that the earth is a perfect sphere, no mountains or valleys, and you have a cannon that you fire parallel to the ground. As the cannonball travels, it will be pulled toward the earth by gravity. If you can make the cannonball travel faster, the curvature of the earth will cause the ground to drop away below it and the cannonball will land farther away. At some speed, the ground will drop away as fast as the cannonball falls, causing the cannonball to actually orbit the earth.

So far as using this energy for space travel, it is the only way things can be done. All objects in space are in some kind of orbit, nothing travels in a straight line. To get to the moon, for example, a rocket goes into an orbit around the Earth that intersects the orbit of the moon.

Answer 4

You have already discussed the fact that planets are moving in their own orbits. So, you are aware that they are "moving." In fact, they are moving VERY fast in their orbits. Diferent planets have different masses, and objects with mass have a quality or feature known as gravity.

If something has gravity, it tends to attract smaller objects to it.

If the smaller object is in fact traveling through space at a high rate of speed, the larger object's pull of gravity may not be enough to capture the object by drawing it completely in. The larger object's gravity may only be sufficient to cause the flight path of the smaller object to bend a little bit, or to bend enough that the smaller object actually circles around the larger one.

The angle of attack, and position of possible strike are most critical in discussions like this. Consider the game of Pool. In that game balls on a flat surface are struck by other balls with the object being to drive the struck ball into a prearranged pocket, or pockets, to score points. If you study that game a bit, you will discover that the point of impact on the struck ball determines the flight path after the ball strike. Note that some shots completely miss the ball aimed at.This is very similar to what happens in Outer Space except for the considerations of gravity.

Answer 5

like each and every of the different solutions, it maintains to be in orbit because of the fact of gravity, yet what they forgot became that the reason the planets do not go plunging into the sunlight or despite they're rotating around is via the fact there's no friction to slow the rotation. Its plenty like rolling a penny down a extensive funnel, if drops to the middle, yet whilst there became no friction, it would stay in a single orbit.

Answer 6

Its called centripedal force kinda hard to explain but basically everything in an orbit travells at a velocity that is tangental to the orbit aswel as expieriencing gravity. Gravity kind of swings it around.

*edit* time and space are not distorted near a massive object, and who ever says so is a complete retard and should die a horriable horiable death and then be forced to learn of by heart every physics book ever written, as boring as they are.
It is completely nothing to do with time an space and as logical an explenation as it might seem this is actually a laughable theory and as a physics student I find it outstanding how somethting so simple such as gravitational orbits can be explained in such a retarded way. Its not a star trek world were living in this is science fact not science fiction. I really cant vent my frustration that a human being could honostly make up and honostly believe such rubbish.

Answer 7

Gravity.

The sun's gravity keeps them inside the solar system and the gravity of other planets and astrological bodies help shape the orbit of a body in space

Answer 8

Imagine you have a twelve hundred foot tall tower. Now imagine you step of the edge. splat. you land about 5 feet away. now we give you a running start. splat. you land about 30 feet away. Now lets say we shot you out of a cannon so you were traveling 14,000 mph. you would begin orbiting the earth! its the same way with planets. they want to keep going in one direction forever, and the sun is trying to pull them in, via gravity. The balance between these forces produces the orbit of a planet.

Answer 9

Yeah, it's all in Einsteins general and special relativity.
Not that hard to understand actually.

Answer 10

where would they have to fall?
