It is presumed to be created by an astronomical explosion in the galaxy that gathered particles, gradually creating our planets and sun.
The Big Bang.
Not so much who but what. Our sun gets the credit for that.
it is how the solar system started
we stay together by gravitational forces and gravital orbitational circles. our solar system was either started by a solar nebula or meteoroids colliding. our solar system was started4,600 years old.
According to the nebular model of the solar system, the original cloud of dust and gas started collapsing about 4.6 billion years ago. The collapse eventually led to the formation of the Sun and the protoplanetary disk, from which the planets, moons, and other solar system bodies formed.
"Our solar system." The "part of our galaxy" that's in our solar system is the solar system.
Our Solar System is called the Solar System, Why?, what do you Aliens call it.
According to the astrophysicists that I believe and follow, our solar system began to form about 4.6 billion years ago.
No. There is one star in our solar system, and no other solar systems within it.
The solar system
My solar system (and yours if you are from Earth) is just called "The Solar System".
When the Moon was formed, the Solar System WAS already a solar system.
There are no exoplanets in our solar system. By definition, an exoplanet is a planet that is not in our solar system.
