They don't. Well, Venus does; it spins the opposite direction relative to all the other planets. Uranus doesn't spin the opposite direction; instead it basically lies on its side and spins. "Why", though ... that's a tricky one unless you can just accept "because they do". Some things just are. There isn't any deep philosophical reason that they should have the axial tilts that they do, they just have them.
In both systems, the Moon goes around the Earth.
Sir Isaac Newton's laws are named the 'Three Laws of Universal Dynamics'. 'Universal' because it means they apply on Earth and out in the Universe. 'Dynamics' , because it means movement. So the laws refer to movement of all objects, be it on Earth or in Space. The Three Laws are ;_ An object(mass) will remain stationary or in uniform motion unless acted upon by a force. Force is directly proportional to acceleration, or Force is directly proportional to mass. ( F = ma) To every force there is an equal and opposite force. In the story of the apple falling on his head, he perceived not only the apple falling to the ground (gravity), but infinitessimally the ground(Earth) moved towards the apple, because the apple has gravitational attraction. NB It has been calculated that two VLCC's (supertanker ships) when berthed along side each other, they have a gravitational force of attraction of 0.5 kg.
3.6 Billion years ago there was an era known as the late heacy bombardment. Then, 3.6 Billion years ago, the planets formed much closer to the Sun. Orbits of the planets drifted for hundreds of millions of years. Until the two 'super planets' of the Solar System; Jupiter and Saturn met. The two planets fell into a resonance pattern of their own.(Their gravitational forces pulled each other and other things around.) Once every cycle they met in the same spot. The Orbital Resonance of the planets was so powerful it managed to push another planet, Neptune. Neptune went flying into the wall of comets surrounding the solar system. For one hundred million years, the Solar System became a shooting ground with comets ploughing through the solar system creating craters on planets. This period was known as the Late Heavy Bombardment. This is what many of the craters we see on our moon and other planets were formed from. It shaped the moon we know today.
Because the solar escape velocity from Earth is 41 km/s, and we are barely able to reach those speeds, even with our fastest spacecraft. Parallel to the ecliptic, we can "cheat" by getting gravity assists from other planets.
All planets and other objects in the solar system orbit the Sun because of its gravity.
because of GRAVITY
No. Of the planets in this solar system, Jupiter, by far, has the strongest gravity.
The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.
Gravity holds the planets in their orbit
because of the gravity of the other planets around them
the sun's gravity
easy gravity :)
The other planets do have gravity.
Because of Earth's size, and considering it as one of the smallest planets, it has a weak gravity compared to the OTHER planets. Most planets have greater gravity because of their size. Earth has a stronger gravity compared to mars, mercury, and venus.
Gravity and heat.
It's true that gravity holds planets in orbit. However, this is due to the gravitational influence of the sun, not the gravitational influence of other planets.
