The document summarizes the main constituents of the Solar System:
1) The Sun
2) Planets like Earth and Mars
3) Natural satellites such as Earth's Moon and Mars' two moons
4) Asteroids which are rocky objects in the asteroid belt between Mars and Jupiter
5) Meteoroids which are small pieces of stone or metal that become meteors when entering the atmosphere
6) Comets which are made of ice and dust that form tails when close to the Sun.

a) Matahari
b) Satelit semulajadi
c) Asteroids
d) Meteoroids
e) Komet
f) Planet
The bigger object in the Solar System (objek terbesar dalam Sistem Solar) An object that moves around a planet (objek yang bergerak mengelilingi planet) A rocky object that moves around the Sun (objek batuan yang bergerak mengelilingi matahari) A piece of stone or metal that floats and travels in outer space (kepingan batu atau logam yang terapung dan bergerak di angkasa lepas) Lump of ice, frozen gases and dusts which moves around the Sun (Gumpalan ais, gas beku dan habuk- habuk yang bergerak mengelilingi matahari) 9 planets in the Solar System (terdapat 9 planet dalam Sistem Solar) Mercury (Utarid) Venus Earth (Bumi) Mars (Marikh) Jupiter (Musytari) Saturn (Zuhal) Uranus Neptune (Neptun) Pluto The Positions of The Planets From The Sun (Urutan kedudukan planet-planet dari matahari) Orbit A path taken by a planet to move around the Sun (Laluan bagi setiap planet untuk bergerak mengelilingi matahari). Science Year 4 NATURAL SATELLITE 1- A natural satellite is an object that moves around a planet. 2- Example : Moon is Earths only natural satellite. It moves around the Earth. Info : All planets have their own natural satellites except for Mercury and Venus. 3- Each natural satellite is much smaller than its planet. Science Year 4 NATURAL SATELLITE Planet Number of Natural Satellite Mercury 0 Venus 0 Earth 1 Mars 2 Jupiter 63 Saturn 48 Uranus 27 Neptune 13 Pluto 3 Science Year 4 MAN-MADE SATELLITE MEASAT 1 & 2 MEASAT 3 Science Year 4 FUNCTIONS OF SATELLITE Science Year 4 1- An asteroid is a rocky object that moves around the Sun. ASTEROIDS 2- Asteroids have different shapes and sizes. 3- Their size can be up to several 100km across but they are usually smaller than planets. 4- Most asteroids lie in a belt between the planets Mars and Jupiter. 5- This area is known as asteroid belt. 6- More than 100,000 asteroids are found in this asteroid belt. Info: scientists think that asteroids may be the remains of planet, which broke up early in the Solar System. Science Year 4 METEOROID 2- There are millions of meteoroids in the Solar System. Most of them are small. Info: Sometimes, a meteoroid may enter the Earths atmosphere. When this happens, the meteoroid will begin to heat up and start to glow. This is called meteor. 3- A meteor looks like a bright streak of light across the night sky. 4- It also called a shooting star. 1- A meteoroid is a piece of stone or metal that floats and travels in outer space. A meteorite crater Meteor Info: Most meteors burn up before they strike the surface of the Earth.
A meteor that strikes the Earth is called a meteorite
A meteorite can make a hole or a crater in the ground when it hits it. Science Year 4 COMETS 1- Comet is lump of ice, frozen gases and dusts which moves around the Sun. 2- A comet does not give off light. But when it gets close enough to the Sun, it will glow and form a long tail. 3- Its tail can sometimes be millions of kilometres along. 4- Example : Halleys Comet. It can be seen from Earth every 76 years
