Why have the planets kept their orbits through millions of years?

Actually, they are moving away more and more.
This is happening because the sun is loosing it's gravitational pull on all of us.
The moon is slowly drifting away from us too.
Pluto's moon is forming the dumbbell effect and might crash and create a mini big bang.
This all might not happen soon, but it is happening slowly.
In the very far future, the sun will either explode and create new planets, or it wilil implode and create a black hole.
we won't be able to see it however because, one, we would have already floated away, or two, the sun would have to swell before it imploded or exploded. so we would have been burned to shreds.
All the planets and sun are becoming farther away, but it is going too slow.

How the planet arrange in the sollar system?
The planets all arrived randomly in their orbits, and over a period of several billion years they have settled into stable orbits.
Who said the planets traveled in oval orbits?
Everyone from the ancient Greeks on knew that the planets move in oval-type orbits, which were simulated by systems of circles. Later, after years of hard work, Johannes Kepler published the laws of planetary motion in 1618 which showed that the orbits are more accurately represented by ellipses, and each planet has its own ellipse with the Sun at one focus. Ellipses make very good approximations to the actual orbits of planets, but the gravitational effects of the other planets, especially Jupiter, mean that the planets depart slightly from true elliptical orbits. That is taken care of by regular updates to the orbital elements of the planets, which are numbers which describe the sizes and shapes, orientation and inclination of all the planets' elliptical orbits.
Would a year on the planets take longer or shorter then an earth year explain?
It depends on the planet. The planets orbiting closer to the sun than earth (Mercury and Venus) have shorter years, because they have smaller orbits, and travel faster. The planets further from the sun (Mars, Jupier, Saturn, Uranus, and Neptune) have longer years because they have larger orbits and travel slower.
How long does Saturn take to orbit the planets in the solar system?
Saturn orbits the Sun like the other planets, it does not orbit anything else. One orbit for Saturn takes 29.4571 Earth years.
What planets orbit interacts with plutos orbit?
Pluto's orbit is more elliptical than the major planets' orbits, and every time it goes round it spends some years inside Neptune's orbit.
What planets orbits the sun every 165 years?
Neptune orbits the sun roughly every 165 years.
How Do Planets Not Hit Each Other?
because they have stable orbits arround the sun... The planets are circling the Sun at different distances. Even though some are in an elliptical orbit, they do not pass close to another one. The planets have been existed for millions of years, so any that would have collided have already done so.

What is the name of the object that orbits around the earth?
Its a thing called 'The Moon'. It's been there for millions of years.
Does the sun rotate around all planets?
The sun doesn't orbit the planets. The planets rotate around the sun and the sun orbits the galactic centre every 225-250 million years.

What planets orbit Jupiter?
Jupiters orbit is a imaginary circle that the planets circle around that is how we count years.
Do planets orbit once a year?
Only the earth orbits the sun once a year. Mars orbits the sun once every 2 years. As you get closer to the sun the planets orbit the sun in less than a year. As you get past Mars, it takes even longer.
If Mercury and Venus and Earth align would the added gravitation pull the Earth closer to the Sun?
No. Venus and Mercury are too small for their extra pull to have an appreciable effect on the Earth. The orbits of the planets stabilized billions of years ago, and there have been millions of alignments since then with little or no effect.
How does the sun change as it ages?
The sun gets bigger and will destroy planets in millions of years. We will probably go extinct.
How long does Saturn take to orbit the planets in the solar system?
Saturn orbits the Sun like the other planets, it does not orbit anything else. One orbit for Saturn takes 29.4571 Earth years.
