THEORIES OFTHEORIES OFORIGIN OF THEORIGIN OF THESOLAR SYSTEMSOLAR SYSTEM

 AstronomyAstronomy is a natural science that study of celestial objects (such as stars, galaxies, planets, moons, asteroids, comets and nebulae), the physics, chemistry, and evolution of such objects, and phenomena that originate outside the atmosphere of Earth, including supernovae explosions, gamma ray bursts, and cosmic microwave background radiation.

The earliest accounts of how the Sun, the Earth and the rest of the Solar System were formed are to be found in early myths, legends and religious texts. None of these can be considered a serious scientific account.

The earliest scientific attempts to explain the origin of the solar system invoked collisions or condensations from a gas cloud. The discovery of 'island universes', which we now know to be galaxies, was thought to confirm this latter theory.

The theory: Hydrogen and other gases swirled around and condensed into our sun and its planets.

The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System. It suggests that the Solar System formed from nebulous material. The theory was developed by Immanuel Kant and published in his Universal Natural History and Theory of the Heaven. Originally applied to our own Solar System, this process of planetary system formation is now thought to be at work throughout the universe.

The theory: One day our sun burst open, and planets and moons shot out at high speeds and went to their respective places, then stopped, and started orbiting the sun, as the moons began orbiting the planets.

The theory: Planets and moons were flying around, and some were captured by our sun and began circling.

The theory: A pile of space dust and rock chunks pushed together into our planet, and another pile pushed itself into our moon. Then the moon got close enough and began encircling the earth.

The theory: Our world collided with a small planet, and the explosion threw off rocks which became the moon, and then it began orbiting us.

The theory: Our planets, moons, and suns spun off from the collision between stars.

The theory: Gas clouds were captured by our sun. But instead of being drawn into it, they began whirling and pushing themselves into planets and moons.
