What role does gravity play in forming and maintaining planets stars and solar systems?
Gravity plays a central role in causing gas to come together in clouds and gradually form dense clouds that eventually generate heat and then start up a nuclear reaction - a star. Gravity also causes rocks to clump together to form planets, and then it holds those planets in orbits round the star that they are close to, to form solar systems.

What is the role that gravity played in the formation of planets stars and solar systems and in determining their motions?
There is no doubt that planets, stars, and solar systems could not ever have formed without gravity. All of these astronomical objects condensed out of clouds of interstellar gas and dust, under the influence of gravity. It is also true that planets orbit stars only because of the gravitational attraction of those stars.
What begins as a nebula?
Stars, planets, solar systems, many objects in space can start as a large unstructured nebula of gas and dust, which can coalesce into massive objects under gravitational influence.
Can new planets be formed?
Not in our own solar system. The orbits of all the planets in the solar system have stabilized, and there isn't enough mass in the remaining asteroids to form a new planet. Else where, however, there are solar systems that are still forming, with new planets that are yet to form.
How would planets stay in space if there was no gravity?
This is the most difficult, yet easiest concept of physics to grasp.If there were no gravity, there would be no planets, no stars, no star systems or galaxies, and no universe. While gravity is the weakest of the four fundamental forces (strong nuclear, weak nuclear, electromagnetic, and gravity), and the least understood. Physicists have been chasing the mystery of gravity for a century or more.The fact remains, that none of what we know would work without gravity. Or, the other three fundamental forces for that matter.
Does gravity pull on planets?
the rule of gravity is the greater mass a planet is the stronger its gravitational pull is so the suns mass is so heavy that its gravitational pull is so strong it keeps all the planets in line

Are planets outside the solar system?
A solar system comprises a star (or combination of gravity bound stars) and their orbiting planets. We think the majority of stars are solar systems an we have detected planets orbiting stars other than the Sun. However in the process of forming a solar system we believe that planets my be permanently ejected from orbiting their stars and flung off into interstellar space. These planets would therefore indeed be outside any solar system.
What effect does the sun's gravity have on the rest of the planets in the solar systems?
That's what's responsible for their staying in orbit, and not flying off.

Which planets has the greatest gravity?
Greatest GravityIn our solar system, the planet with the greatest gravity is Jupiter.and lowest gravity planet is Mercury. (Pluto's gravity is lower than that of Mercury, but Pluto is no longer considered a planet.)Jupiter.
How can a planet be created?
Solar systems are formed when gravity collects enough dust and gas together to form a sun and planets. Other masses are added to the system over time. Gravity is the driving force.
Can new planets be formed?
Not in our own solar system. The orbits of all the planets in the solar system have stabilized, and there isn't enough mass in the remaining asteroids to form a new planet. Else where, however, there are solar systems that are still forming, with new planets that are yet to form.
What is the relationship of planets and stars with solar system galaxies and the universe?
Most planets orbit stars forming stellar systems. Stars are not part of the solar system which is simply the stellar system for our star - otherwise known as the sun. Stellar systems together form galaxies and these form a part of the universe.
What is the relationship between planets stars and galaxies?
Planets generally orbit around stars. (Some interesting speculations suggest that there may be "free planets" that are not near any star.) Billions of these solar systems orbiting their common center of gravity form a galaxy.
What is the process gravity helps form stars planets and solar systems by the gradual gathering together of smaller pieces?
Gravity causes smaller pieces of matter, such as gas and dust particles, to come together and accumulate over time. As more material gathers together, the gravitational force increases, leading to the formation of stars, planets, and solar systems. This process is known as accretion.

How do ice clouds in interstellar space contribute to the formation of new stars and planets?
Ice clouds in interstellar space play a crucial role in the formation of new stars and planets by providing the raw materials needed for the process. These ice clouds contain elements and molecules that can clump together under the force of gravity, eventually forming dense cores that collapse and give rise to new stars and planetary systems.
