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.

A star is made from a nebula which is a spinning cloud of gas and dust and a star is formed when the gas and dust contract under gravity and get a hot enough tempreture and pressure for nuclear fusion and a star is born, that explains the galaxy bit cause a galaxy is a collection of stars.
The planets are formed from left over material from the formation of the sun and the material clumps together because as the material has an attractive force it attracts more and more material which increases the gravity and a planet is formed.

∙ 6y agoBefore, the solar system was just a stable nebula, until suddenly it becomes unstable (maybe because of a supernova). As the nebula rotates, the center is getting clumped together to form the sun, and the rest of the nebula becomes flat (due to its rotation) and turn into a planetary disk. Rocks will clump together, making their gravity stronger, thus pulling more rocks, making their gravity even stronger, until it becomes a planet and when the planetary disk is blown away by the newborn sun.

∙ 8y agoGravity is what made matter clump together to form stars and started the processes that led to the formation of planets. Without gravity none of that would ever have happened.

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.
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 primary difference in composition between the Sun and the terrestrial planets is?
Dependant on how the debris from supernovae is moving, the proportions of certain materials present, and the initial conditions of solar systems forming different combinations of terrestrial and Jovian planets are formed. Terrestrial planets are comprised of heavier particles (ie. of higher relative atomic mass) meaning they have stronger gravity which leads to higher density planets than the gaseous Jovian planets. A Jovian planet can be thought of as a failed star - it has all the elements needed to fuel nuclear fusion, but not enough gravity to attain the nuclear activation energy required. So the Sun started as a large cloud mostly comprising of gases, and terrestrial planets were formed from clouds mostly consisting of heavy solids.
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.
What is the process gravity helps form stars planets and solar systems by the gradual gathering together of smaller pieces?
collapsing
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.
