Study Notes
Theories on the Origin of the Solar System
- Decartes' Vortex Theory proposed that the solar system formed from pre-solar materials in a whirlpool-like motion, resulting in bodies with nearly circular orbits.
- Buffon's Collision Theory suggested that the planets were formed through the collision of the sun and a giant comet.
- Kant-Laplace Nebular Theory stated that the solar system originated from the collapse of a nebula due to gravitational pull, forming different planets.
- A nebula is a cloud of gas and dust.
- Jeans-Jeffrey's Tidal Theory proposed that planets were formed through different mechanisms, with particles torn out of the sun playing a role.
- The Solar Nebular Theory involves multiple stages in the formation of the solar system.
- The first stage is the formation of planetesimals, which are different particles.
- These planetesimals eventually coalesce to form planets.
- Heliocentric theory places the Sun at the center of the solar system.
- Geocentric theory suggests that the Earth is at the center of the solar system.
- These theories offer different explanations for the formation of the solar system.
- They are proposed by notable scientists such as Rene Decartes, George-Louis Leclerc, Comte de Buffon, Immanuel Kant, Pierre-Simon Laplace, James Hopwood Jeans, and Harold Jeffreys.
