Solar system

SOLAR SYSTEM AND BEYOND THE SOLAR SYSTEM

Is the collection of planets, moons, and all other objects that move around the earth.

THE DIFFERENT PLANETS IN THE SOLAR SYSTEM

Beyond the solar system

The Solar System[a] consists of the Sun and the astronomical objects gravitationally bound in orbit around

it, all of which formed from the collapse of a giant molecular cloud approximately 4.6 billion years ago.

Bodies outside of the solar system are divided into simple, extended and compound objects. Simple objects are single

bodies in space, and extended objects are generally diffuse, amorphous entities such as nebulae and universal energies like cosmic background radiation. Compound objects are generally combinations or groupings of simple objects,

though they can include nebulae where large clusters of stars are contained.

SOLAR SYSTEM AND BEYOND THE SOLAR SYSTEM

THE SUN

The sun is the centre of our Solar System. All the planets and other objects orbit around it.The sun makes life on our planet possible by giving us great amounts of light and heat. Most of our energy comes from the sun. Plants need sunlight to make their own food and give out oxygen. All living things need oxygen. The sun is a huge ball of white-hot gases. Permanent nuclear reactions produce the sun’s light and heat

HOW ARE THEY LINKED

The cosmic abundance of oxygen is an important numberin a wide variety of scenarios. Several debates have over theyears focused on the disagreements about the oxygen abundanceof stars and the disparities between estimated abundancesfor different kinds of astronomical objects. (Gummersbach etal. 1998; Rolleston et al. 2000)

THE SUN AND THE ASTRONOMICAL OBJECTS

Our solar system is located in the outer reaches of the Milky Way Galaxy, which is a spiral galaxy. The Milky Way Galaxy contains roughly 200 billion stars. Most of these stars are not visible from

Earth. Almost everything that we can see in the sky belongs to the Milky Way Galaxy.

The sun is about 26,000 light-years from the centre of the Milky Way Galaxy, which is about 80,000 to 120,000 light-years across (and

less than 7,000 light-years thick). We are located on one of its spiral arms, out towards the edge. It takes the sun (and our solar system) roughly 200-250 million years to orbit once around the Milky Way.
