From the collapse of a nebula made of gas and dust. As the cloud contracted one dense clump formed in the center which would become the Sun. Everything else was made from the leftovers.
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.
Because that is how the Solar system formed.
Here is a very basic answer... Our solar system was what happened when remnants of a star (that exploded) were pulled together by gravity. First formed planets, then formed the Sun. This is how almost every other solar system is formed...
The Sun formed first, so it is the youngest compared to the planets.
The solar system formed from the gravitational collapse of a cloud of interstellar gas.
B. The young sun's solar winds pushed gases outward to the outer solar system.
When the Moon was formed, the Solar System WAS already a solar system.
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.
Well the Sun has the most mass in the entire solar system, so it would naturally be found in the center, with objects of lesser mass orbiting it.
The universe was already vast when the Sun and our solar system formed about 4.6 billion years ago. The exact size of the universe at that time is difficult to quantify, but it was significantly larger than the scale of our local solar system.
The solar nebula formed (~7 billion years ago)The solar nebula collapsed into the disk of the solar system (~6.5 billion years ago)The sun formed and ignited fusion at the center of the disk of the solar system (~6 billion years ago)The planets, asteroids, and comets formed from the outer parts of the disk of the solar system (~4.5 billion years ago)
Solar means sun and the sun is the star at the center of our "system" ,thus solar system (sun system).
