What is the timeline of the solar system?
13.8 billion years ago: The Big Bang forms the universe. 4.6 billion years ago: A group of protostars, one of which will become the Sun, form from a cloud of debris left by prior star explosions in the Milky Way. 4.59 billion years ago: The giant planets Jupiter, Saturn, Uranus, and Neptune form around the protosun.
How the solar system was formed timeline?
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 is the Earth timeline?
Eons
| Eon | Time (mya) |

| Hadean | 4,540–4,000 |
| Archean | 4,000–2,500 |
| Proterozoic | 2,500–541 |
| Phanerozoic | 541–present |
How did the solar system start?
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 is the first stage of a solar system?
The first stage of planetary development is called differentiation, the settling of dense material, like iron-rich minerals, into the center of a planet and the rising of less dense material, such as silicon-rich minerals, to the surface.

What was the earliest Solar System to exist?
Heraclides (330 B.C.) developed the first solar system model, placing the planets in order from the earth because at that time the earth was considered the center of our universe.
Does our Solar System have a history?
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 is the history of our Solar System?
The most widely accepted theory of planetary formation, known as the nebular hypothesis, maintains that 4.6 billion years ago, the Solar System formed from the gravitational collapse of a giant molecular cloud which was light years across. Several stars, including the Sun, formed within the collapsing cloud.
What is the Order of the Solar System?
Our Solar System has eight planets which orbit the sun. In order of distance from the sun they are; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
