Out of an accretion disc. A disc of materials left over from the formation of a star (in this case our sun) orbiting. Small particles bump into each other and stick. Slowly over time it isn't the rigidness of the particles in that environment which causes them to stick, but at a certain size it will begin to bend space and time to where the larger chunks have significant gravity so other particles are drawn towards them. As the bigger pieces collide over time they also begin to hold together until they have what is known as hydrostatic equilibrium. This is where the object has enough gravity to hold a roughly spherical shape. Thus a planet is born. Gas planets are slightly different only in the respect that solid portions are not as visible; they fall towards the center.

What are solar system?

they are a star and leftover planets that formed.


What evidence has been used to show that the Earth and all the planets of the solar system were formed simultaneously?

when told that let a solar system be formed it was formed


How are the planets in the solar system formed as?

Planets in the solar system are thought to have formed from a giant rotating disk of gas and dust around the young Sun, known as the solar nebula. Small particles in this disk collided and stuck together, gradually growing into planetesimals and eventually forming protoplanets and then fully-fledged planets through accretion and gravitational interactions.


What shape is the solar system?

The solar system is roughly a flat, disk-like shape, with most planets orbiting the Sun in relatively the same plane. This configuration is due to the way the solar system formed from a rotating cloud of gas and dust, which flattened out into a disk as the planets formed.


What are the theories of the origins of solar system?

Here is a very basic answer... Our solar system was what happened when remnants of a star (that exploded) were pulled together by gravity. First formed planets, then formed the Sun. This is how almost every other solar system is formed...


Were any other planets formed in the solar system other than the present eight planets?

Actually, there are 18 known planets in our solar system, as well as two known protoplanets. For a complete list of objects in the solar system, see the related links.


What is a piece of rock that is similar to the material that formed the planets?

Asteroids are pieces of rock that are similar in composition to the material that formed the planets in our solar system. They are remnants from the early stages of solar system formation and can provide clues about the processes that led to the formation of planets.


Why are all planets in a solar system?

Not all planets are associated with a star. While most planets are in a solar system as they are the leftover material from star formation. there are some free roaming planets in space not associated with a solar system. They may have been formed as part of a planetary system but have escaped due to gravitational interactions or collisions with other planets in the system.


Are the moons as old as the planets that they circle?

In most cases, the moons are about as old as the planets they orbit, perhaps slightly younger. Most objects in the solar system formed when the solar system did.


How did planets get to the Milky Way?

The planets were formed in the Milky Way. Our Galaxy (Milky Way) is older than the planets of our solar system.


When were planets formed and how?

The planets of our solar system were formed at different times, the earth is known to have formed as a planet about 4.6 billion years ago but other planets in the solar system may have formed earlier or later as they were quite conceivably not formed in the same manner as the earth


What came first the planets formed or the earth?

at present the theory is that all of the planets that make up the solar system were formed at the same time when the Solar System condensed out of a cloud of gas about 4.5-4.7 billion years ago.
