There are two main types of satellites: natural satellites like the Moon, and artificial satellites built by humans and launched into space using rockets to orbit Earth. Artificial satellites are used for communication, collecting weather and other scientific information, and making maps. Other objects in space include comets, asteroids, stars grouped into galaxies, and our solar system is located within the Milky Way galaxy. The solar system contains eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury and Venus are made of rock, while the others are made of gases, with Jupiter being the largest planet and Saturn having iconic rings.

1. Types of satellite
1- Natural satellite
Moon

2. Types of satellite
2- Artificial satellite

3. Built by people and launched by rockets into
space, they orbit around the Earth.

5. Types of satellite
2- Artificial satellite
It is used to :
a) Communication
Like broadcasting T.V programmes, telephone calls
b) Collecting information to help with weather
forecasts.
c) Map making

6. Space telescope
Collects information about the planets and
stars.

7. Space probes
They do not orbit the earth. They travel to
other planets to collect scientific information.
Some space probes orbits around other
planets, some land on them

8. • The Space Race was a 20th-
century (1955–1972) competition
between two Cold War rivals, the
Soviet Union and the United
States, for supremacy (superior)
in spaceflight capability

13. Stars form immense group called galaxies
A galaxy can contain many millions of stars.
