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 controls the motions of the planets?
Gravity is what sets the planets in motion. The force that keeps them in motion is known as inertia in the law of physics.
What affect does gravity have on all matter in the universe?
Because of the existence of 'gravity', there are a pair of equal forces between every two specks of mass in the universe. Greater masses and smaller separations result in greater forces. These simple facts lead to the formation of galaxies, stars, and planets, and to virtually all of the motions we see, including orbits.
Which planets' motions were described with epicycles in the Ptolemaic system?
All the known planets
This scientist compared the motions of electrons in atoms to the motions of planets orbiting the sun?
Niels Bohr.
What is gravity and how does it affect planets and the oceans?
gravity is something that can affect the planets.
Why do planets have circular and elliptical motions in the solar system?
The scientific explanation lies in Kepler's laws of planetary motions, which were discovered by Newton to be linked with the law of gravity. All the planets have elliptical orbits, and many of those are close being circular.
Newton applied his laws of motion to the problem of the motions of the planets. he assumed that it was gravity that held them into their orbits. true or false?
true

Why is gravity vital?
It depends on what you think it is vital for. For life? Almost certainly! If only because gravity is required for the formation of stars and planets.
What was gravity s role in the formation of the universe?
gravity clumped stars together, created planets and stopped everything from moving at the speed of light

What role did gravity play in the formation of the planets?
Gravity, of course has a central role in formation of planets. It's believed that the planets origin can be traced to the debris swirling around a young star. The term used for coming together of particles or bodies and joining together is 'accretion'. Gravity is the reason behind accretion . Small debris join together due to accretion and this accretion occurs further to give rise to larger and larger bodies like planets . Without gravity, this could never have occurred.
What is the only planet that is not spherical in shape?
All planets are 'round' because of gravity. With the formation of the Solar System, gravity gathered gas and dust into clumps which became larger and eventually planets. The collision of these pieces caused planets to become hot and molten and gravity pulled the molten material towards the planet's centre in the shape of a sphere. The planets cooled and remained spherical
Where do the planets get gravity?
Planets have gravity because they have mass.
The planets were originally giant comets captured by the sun?
Our current theory of the formation of our solar system is that the planets formed more or less in their present orbits. We do not believe that the planets (with the exception of Pluto) were "captured" by the Sun's gravity.
Which planets' motions were described with epicycles in the Ptolemaic system?
All the known planets
What role does gravity have in the formation of the solar system?
It affects the rotationand revolution of the planets surrounding the sun. it also affects the shape in which they rotate.
