OUR SOLAR SYSTEM :

OUR SOLAR SYSTEM Done by Faten Zaidan Miss Maha

WHAT is our solar system ?!:

WHAT is our solar system ?! The Solar System is made up of all the planets that orbit our Sun… In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, and dust and gas.

>> A note..:

>> A note.. Because the Sun is so large, its powerful gravity attracts all the other objects in the Solar System towards it. At the same time, these objects, which are moving very rapidly, try to fly away from the Sun, outward into the emptiness of outer space. The result of the planets trying to fly away, at the same time that the Sun is trying to pull them inward is that they become trapped half-way in between. Balanced between flying towards the Sun, and escaping into space, they spend eternity orbiting around their parent star.

Slide 4:

HOW did the solar system form?!

WHAT are asteroids ?!:

WHAT are asteroids ?!

Slide 6:

Scientists believe that the Solar System evolved from a giant cloud of dust and gas. This dust and gas began to collapse under the weight of its own gravity. moves around the center of the drain in a circle. At the center of this spinning cloud, a small star begin to form. This star grew larger and larger, as it collected more of the dust and gas that were collapsing into it.

An asteroid is a large rock in outer space. Due to their smaller size, asteroids do not have enough gravity to pull themselves into the shape of a ball.  The asteroid belt is divided into an inner belt and an outer belt. The inner belt which is made up of asteroids that are within 250 million miles of the Sun contains asteroids that are made of metals. The outer belt, which includes asteroids 250 million miles beyond the Sun, consists of rocky asteroids. These asteroids appear darker than the asteroids of the inner belt, and are rich in carbon. :

Still two points about asteroids..:

Still two points about asteroids.. HOW many asteroids are there? 26 very large asteroids have been discovered! But there are still millions of smaller ones that we have yet to see because they are too tiny, only a mile or so across. WHERE did the Asteroid Belt come from? Asteroids are left over materials from the formation of the Solar System. These materials were never incorporated into a planet because of their proximity to Jupiter's strong gravity.

THE SUN :

THE SUN Our Sun is not unique in the universe. It is a common middle-sized yellow star which scientists have named Sol. This is why our system of planets is called the Solar System. There are trillions of other stars in the Universe just like it. Many of these stars have their own systems of planets, moons, asteroids, and comets.

THE FAMILY OF THE SUN :

THE FAMILY OF THE SUN The Sun is by far the largest object in the Solar System. 98 % of all matter within the Solar System is found within the Sun. Planets , moons, asteroids, minor planets, comets, gas , and dust would all combine to make up only 2 % of all the matter in the Solar System !!

Our solar system consists of the Sun, the planets  Mercury, Venus, Earth, Mars, Jupiter,  Saturn,  Uranus, Neptune, and Pluto. :

FINALLY !! Our solar system consists of the Sun , the planets Mercury , Venus , Earth , Mars , Jupiter , Saturn , Uranus , Neptune , and Pluto . Sun : 99.85% Planets : 0.135% Comets : 0.01% ? Satellites : 0.00005% Minor Planets: 0.0000002% Meteoroids : 0.0000001% Interplanetary Medium: 0.0000001%
