The second theory says that the moon is a captured asteroid.
gravity
It's the fission theory, if anyone wants the wrong answer.
The capture theory says that the moon was originally orbiting the sun, but it passed to near the earth, and became the moon. The biggest problem with this theory is that this action would have created so much heat that it would melt the earth.
coformation(or sister) theory
I'm not sure its a real "theory" as much as it is science for you see when the earth was being created chunks of meteorite was flying around crashing and combing and making gravity pulls sucking in more rocks and colliding with larger ones and earth's "followers" had crashed into earth breaking off pieces then those pieces collided and made the moon
As far as I know it's only at the stage of being a conjecture and is not yet a theory.
the collision ring theory is a theory about how the moon formed. It says that a planet sized objoct hit earth while it was still young and exploded on inpact. Then the debris formed the moon as the magma cooled.

the giant impact hypothesis is currently the accepted theory. It basically says that a large asteroid collided with the earth, knocking debris from the earth into space. this debris then formed together over time to form the moon.
The most widely accepted theory for how Earth's moon was formed is called the impact theory. It says that the moon formed from a collision between Earth and a Mars-sized object about four and a half billion years ago.
Scientists suggest the most likely theory is the collision theory. It states the Earth was hit by a planetesimal (a planetoid) and then Earth threw out a cloud of dust and gas. Gravity then formed the ring into a ball. The sister theory says the Earth and moon formed separately but close together in the Solar System. The fission theory states the rapidly spinning proto-Earth split off a chunk of magma and the blob of rock became the moon. The capture theory says the moon was a planetesimal (or planetoid) that the Earth captured.
