It was a nebula.
It is sometimes called the Solar nebula.
It is sometimes called the Solar nebula.
The solar system formed from the gravitational collapse of a cloud of interstellar gas.
Astronomers believe that the solar system formed from a giant rotating cloud of gas and dust called the solar nebula. As the cloud collapsed under its own gravity, it began to spin faster and eventually formed a flat, rotating disk. The Sun formed at the center, while the planets and other objects in the solar system accreted from the material in the disk.
Solar nebula.
The Solar System formed from a cloud of gas, that collapsed.
A cloud of gas and dust.
Yes, the solar system including our Sun and planets is believed to have formed from a large disk of gas and dust called a proto-disk or proto-solar disk, due to gravitational effects. It is currently thought that several stars formed from the same cloud as our Sun.
That is called an accretion disk or a proto-Solar system.
planetary
The sun formed from a large cloud of gas and dust in space about 4.6 billion years ago. As gravity caused the cloud to collapse, it heated up and formed the sun at the center, while the remaining material in the cloud eventually formed the planets in the solar system.
The hypothesis on how the solar system was formed is known as the solar nebula theory. This theory posits that the solar system formed from a massive, rotating cloud of gas and dust called the solar nebula. Over time, gravity caused the material in the nebula to clump together, eventually forming the sun and the planets.
