how were the planets of our solar system born?

Question

details about the sun would be helpful as well.

Answer 1

The solar system, including our sun, formed when large gas clouds condensed and cooled. These gas clouds came from other novae or super-novae ("exploding" stars). That means our sun has not been around since the beginning of the universe! And of course, neither has the solar system.

How do we know this? Elements higher on the periodic table, specifically ones higher than Iron, can only be fused by the tremendous pressure and heat created by novae. Obviously metals and other elements higher than Iron exist within the Earth.

Answer 2

the theory says that long after a supernova, the gases and dust left over began collecting and condensing because of gravity to form what is called a protostar. This eventually grew so large that it started an internal nuclear reaction (fusing hydrogen into helium) and became our sun

The dust and gas left over orbited around the sun, but were never close enough to become a part of it. These slowly condensed forming the planets-- the four terrestrial (rocky) planets close to the sun and the gas giants farther away.

However, astronomers have not found a planet anything like those in our own solar system. All planets outside of our system have been super-heated and very fast-spinning, so scientists are not sure this is how all planets are formed.

Answer 3

A wedge shaped mass of rocky material the was ejected from a super nova crashed into part of the surrounding hydrogen field.
If formed a massive smoke ring,the momentum of the which initiated the formation of the solar system after which gravity did the rest.
The sun formed from the hydrogen field and most of the planets from the rocky material.

Answer 5

little before my time they say the Big Bang which when the Scientist explains it sounds like an Act of God

Answer 6

increasingly high gravity as mass increased (meteors and such smashing into each other).
