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

14.3 Formation of the Solar System

Rotation of the Solar Nebula We can use the concept of angular momentum to trace the evolution of the collapsing solar nebula. The angular momentum of an object is proportional to the square of its size (diameter) divided by its period of rotation (D 2 P) (D 2 P).If angular momentum is conserved, then any change in the size of a nebula must be compensated for by a proportional

Origin of the Solar System

Early scientific theories The Kant-Laplace nebular hypothesis. Kant''s central idea was that the solar system began as a cloud of dispersed particles. He assumed that the mutual gravitational attractions of the particles caused them to start moving and colliding, at which point chemical forces kept them bonded together. This model for

We have known since the time of the Copernican revolution that the Sun is the dominant object in the Solar System. A tour of the Solar System reveals some impressive worlds, but the Sun dwarfs them all. The sum of the mass of all the planets combined is barely 0.2% of the mass of the Sun. People have known for thousands of years that the planets all appear to move across a thin

Historical models of the Solar System

Historical models of the Solar System first appeared during prehistoric periods and remain updated to this day.. The models of the Solar System throughout history were first represented in the early form of cave markings and drawings, calendars and astronomical symbols. Then books and written records became the main source of information that expressed the way the people

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.

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
