The Solar Nebula

By Kick Butt Kyle

What is the Solar Nebula Theory?

The solar nebula theory, also known as the nebular hypothesis, is the most widely accepted model explaining the formation and evolution of our solar system.

What does the SNT state?

  1. The Solar Nebular Hypothesis describes the formation of our Solar System from a nebula cloud made from a collection of dust and gas. It is believed that the sun, planets, moons and asteroids were formed around the same time around 4.5 billion years ago from a nebula.

Who developed the SNT?

This nebular hypothesis was first developed in the 18th century by Emanuel Swedenborg, Immanuel Kant, and Pierre-Simon Laplace. Kant argued that gaseous clouds—nebulae, which slowly rotate, gradually collapse and flatten due to gravity and eventually form stars and planets.

When was the theory developed?

The SNT was developed in 1734.
