This model also explains the spacing of the planets. Studies suggest that if two large bodies started growing in orbits that were too close together, they would eventually grow large enough, as they gravitationally cleared out their orbit, to attract each other gravitationally, collide, and merge this way, the solar nebula divided into donut-shaped zones around the Sun, each

What Is the Nice Model, or How Did Our Solar System Form?

This new model that they created was an attempt to explain some of the mysteries of the early solar system, including what caused the Late Bombardment Period and what pulled the Kuiper Belt together. Though not a definitive solution, it nonetheless is another stepping stone to the ultimate truth of how the solar system evolved.

Model the solar system with distances from everyday life to better comprehend distances in space; The solar system 1 consists of the Sun and many smaller objects: the planets, their moons and rings, and such "debris" as asteroids, comets, and dust. Decades of observation and spacecraft exploration have revealed that most of these objects

While they often showed relative sizes, these models

Solar System Facts

Our solar system includes the Sun, eight planets, five dwarf planets, and hundreds of moons, asteroids, and comets. In other cases, planets did not form: the asteroid belt is made of bits and pieces of the early solar system that could never quite come together into a planet. Other smaller leftover pieces became asteroids, comets

Placing the Sun at the center brings a certain symmetry and simplicity to the model of the solar system. In Ptolemy''s model, Mercury and Venus are special because they revolve around empty points between the Earth and Sun. Copernicus has all the planets orbiting the Sun in the same sense. He simply explains the fact that Mercury and Venus always appear close to the Sun.

History of Solar System formation and evolution hypotheses

French philosopher and mathematician René Descartes was the first to propose a model for the origin of the Solar System in his book The World, written from 1629 to 1633. In his view, the

OverviewHistoryFormationSubsequent evolutionMoonsFutureGalactic interactionChronology

There is evidence that the formation of the Solar System began about 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. Most of the collapsing mass collected in the center, forming the Sun, while the rest flattened into a protoplanetary disk out of which the planets, moons, asteroids, and other small Solar System bodies formed.

The publication of Nicolaus Copernicus''s (1473-1543) De Revolutionibus Orbium Celestium in 1543 was attended by no official opposition.

· The solar system''s several billion comets are found mainly in two distinct reservoirs. The more-distant one, called the Oort cloud, is a spherical shell surrounding the solar system at a distance of approximately 50,000 astronomical units (AU)—more than 1,000 times the distance of Pluto''s orbit. The other reservoir, the Kuiper belt, is a thick disk-shaped zone whose main
