THE SOLAR SYSTEM

*The Sun

*The Sun is the star at the center of the Solar System. It is almost perfectly spherical and consists of hot plasma interwoven with magnetic fields. It has a diameter of about 1,392,684 km (865,374 miles), around 109 times that of Earth, and its mass (1.989×1030 kilograms, approximately 330,000 times the mass of Earth) accounts for about 99.86% of the total mass of the Solar System. Chemically, about three quarters of the Sun's mass consists of hydrogen, while the rest is mostly helium.

•The Sun formed about 4.6 billion years ago from the gravitational collapse of a region within a large molecular cloud. Most of the matter gathered in the center, while the rest flattened into an orbiting disk that would become the Solar System. The central mass became increasingly hot and dense, eventually initiating thermonuclear fusion in its core. It is thought that almost all stars form by this process.

Our earth is the third planet from the sun .It is the only planet on which life is known toexist. All the factors necessary for life are present only on earth .It has oxygen ,carbon dioxide and water in the liquid form. It has a layer in its atmosphere which stops harmful UV rays of the sun from reaching the earth The earth’s axis is not perpendicular to the plane of its orbit but titled at an angle of 23.5 degree .Whenthe earth’s northern hemisphere is tilted towardsthe sun , it is summer in the northern hemisphere, while itis winter in the southern hemisphere.

A small Solar System body (SSSB) is an object in the Solar System that is neither a planet, nor a dwarf planet, nor a satellite. The term was first defined in 2006 by the International Astronomical Union.

All other objects, except satellites, orbiting the Sun shall be referred to collectively as "Small Solar System Bodies" ... These currently include most of the Solar System asteroids, most Trans- Neptunian Objects (TNOs), comets, and other small bodies.
