Hi guys, I'm not sure if this topic fits here, but can anyone tell me about the origin of planets? Like how is our planet formed?

HallsofIvy said:I think "toward itself" is misleading. All matter has a slight gravitational pull toward other matter.
Jame said:The elements that make up the icy outer planets would evaporate under the heat of the sun and therefore can't make solid planets. These were instead transported outwards by various mechanisms.
The distance at which the temperature is low enough for the ejected material to condensate[sic] is called the "frost line" and coincides, not accidentally, with Jupiter's orbit. Once they condensate[sic] they will start to lump together and form planets.
The Earth formed approximately 4.5 billion years ago through a process called accretion. This involved the gradual accumulation of dust and gas particles in a disk around the young sun, which eventually formed into larger bodies like planets.
The early Earth was primarily composed of molten rock and metal due to the high temperatures during its formation. As the Earth cooled, heavier materials sank to the center, forming the core, while lighter materials rose to the surface, forming the crust.
The most widely accepted theory for the formation of the Moon is the "Giant Impact Hypothesis." This proposes that a Mars-sized object collided with the early Earth, sending debris into orbit which eventually coalesced to form the Moon.
Water likely arrived on Earth through comets and asteroids during the early stages of the solar system's formation. It then became trapped in the Earth's mantle and was later released through volcanic activity, forming the oceans.
Scientists study the origin of planets through a combination of observational data, computer simulations, and laboratory experiments. By studying other planets in our solar system and beyond, as well as analyzing meteorites and other space debris, they can piece together the processes that led to the formation of our own planet.
