NEW SOLAR SYSTEM FORMS FROM HUGE GAS CLOUD
Gas cloud produces molecules
The plasma of the universe, condenses in a cloud with a diameter of hundreds of thousands times the distance from Earth to the Sun. Gravity produces molecules of particularly hydrogen.
Gas cloud collapses into a star
Over 10-100,000 years, the cloud collapses under its own weight into a protostar surrounded by a rotating disc. The star absorbs material and makes gases flow out from the poles.
Disc of dust and gas becomes planets
The protostar and its rotating disc continue to attract molecules, until the gas cloud is completely gone. Over 350 million years, dust and gas in the disc condense into planets and other objects.
