That is called an accretion disk or a proto-Solar system.
That theory is called the "Big Bang Theory" There was a a huge explosion & the universe & everything it it was instantly formed to make all the planets & galaxies.
That description matches the word you may be thinking of called a nebula. A nebula is the large cloud of gas and dust that had formed our solar system.

The solar system formed from the gravitational collapse of a cloud of interstellar gas.
The celestial bodies of our solar system are believed to have formed from the solar nebula. The solar nebula was a giant cloud of dust and gas that was left behind after the formation of the sun.
The formation of our solar system began around 4.568 billion years ago with the collapse of a large molecular cloud, mainly hydrogen, which gradually came together under its own gravity to give birth to our solar system.
The solar system is believed to have formed about 5 billion years ago, and by the way, why do you call it YOUR solar system? Do you come from a different solar system? Because if not, then it's OUR solar system.
The solar system did not form from a nebula at all. Our solar system formed from a rotating cloud of gas and dust, our sun formed at the center and planets formed from the surrounding matter. when our sun became large enough to support nuclear fusion, the solar wind created blew away most of the gases present. A planetary nebula is formed after a star runs out of fuel (Helium) and collapses inward on itself due to the massive amount of gravity and the now unstable balance of the star. the pressure then becomes so great that the gases that had been pulled inward explode outward at an incredible speed. The Cats Eye Nebula is a good exampleFile:NGC7293_(2004).jpg
The planets in the solar system are formed by fragment of the original cloud.
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.

Astronomers Believe That The Solar System Began As A Huge Cloud Of Dust And A Gas Called ''NEBULA''
mostly hydrogen and helium
