Composition of the universe

Right after big bang:

75 hydrogen

25 helium

Nothing else really

Today:

70 hydrogen

28 helium

2 everything else

New cards

Formation of solar system

Nebular collapse: gravity

Spins faster: conservation of angular momentum

Heats up: conservation of energy

Becomes disk: collisions forcing common motions

Star formation: the dense center of nebula continues to collapse until nuclear fusion starts

New cards

Formation 2

Condensation: frost line, where different materials condense.

Inside frost line: rocks and metals

Outside frost line: rocks metals and hydrogen compounds

Accretion: snowball effect

New cards

Formation 3

Gas capture: large moons of giant planets form from giant planets own mini disks

Solar wind clearing: gas gets blown away, solid bodies remain

Heavy bombardment/ explain exceptions

Giant planets migration: planet and smaller bodies still move around because they interact with each other through gravity
