As the cloud spun, it collected into a disc called a solar nebula.

Then, about 4.68x10 years ago, the solar nebula began to contract, rotate and gain angular momentum.

Therefore, the meteorite must have formed in the solar nebula before the Al had decayed.

The solar nebula or a protoplanetary environment are possible places of formation.

Earth is estimated to have formed 4.54 billion years ago from the solar nebula, along with the Sun and other planets.

This is important because comets are made up of material left over from the solar nebula after the planets were formed.

The first atmosphere would have consisted of gases in the solar nebula, primarily hydrogen.

These elements constituted only 0.6% of the material in the solar nebula.

These rocks are called meteorites and provide information about the primordial solar nebula.

If that had not happened, then the solar nebula could not have collapsed.
