How the solar system was formed step by step?
The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.

What are the four steps of the formation of the solar system?
After becoming distinct planets, they went through four stages of formation: Differentiation, Cratering, Flooding and Surface Evolution.
How is the solar system structured?
The solar system consists of the sun, nine planets, their 158 moons and a belt of asteroids and comets. Venus, Earth, Mercury, Mars and the sun are all parts of the inner solar system. Outer solar system consists of Neptune, Saturn, Uranus, Pluto and Neptune.
What is the origin of solar system?
Formation. Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material.
What are the theories of the formation of the solar system?
The most widely accepted hypothesis of planetary formation is known as the nebular hypothesis. This hypothesis posits that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years.
How many steps are there in the formation of a solar system?
Answer: Three Stages Of Formation Of Planets: After becoming distinct planets they went through four stages of formation: Differentiation Cratering Flooding and Surface Evolution. For Earth these changes led to the planet we know today layered with an iron core a weathered shifting surface water and life.
In what order are solar systems formed?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine.
What are the basic steps in the formation of our solar system from first event to last?
The solar nebula contracted; the protosun formed; collisions of solid matter formed planetesimals; accretion of matter turned the planetesimals into protoplanets; the protoplanets ultimately became the eight planets of our solar system.
