Comets are small icy objects with two tails made of gas and dust that formed over 4.6 billion years ago in the early solar system and have highly elliptical orbits. Asteroids are small rocky or metallic objects that orbit the sun, ranging in size from meters to hundreds of kilometers wide with irregular shapes and cratered surfaces. Meteors are streaks of light seen when meteoroids - space rocks or fragments that can be from comets, asteroids, moons or Mars - enter the Earth's atmosphere. Some meteoroids survive entry and land on Earth's surface as meteorites.

1. COMETS,
ASTEROIDS
AND
METEORS

2. COMET
 Is a small icy material which have
two tails made up gas and dust.
 Leftover
of
solar
system
formation for about 4.6 billion
years ago. typically have highly
elliptical (oval-shaped), offcenter orbits that swing near the
Sun.

4. ASTEROIDS
 A small rocky or metallic body that orbits
the Sun. Hundreds of thousands of
asteroids exist in the solar system.
Asteroids range in size from a few meters
to over 500 km (300 mi) wide. They are
generally irregular in shape and often have
surfaces covered with craters. Like icy
comets, asteroids are primitive objects left
over from the time when the planets
formed

6. Meteor,
meteoroid and
meteorites

7. meteor
 A meteor is a light phenomenon or a
streak of light as observed from earth
when a meteoroid passes through
Earth’s atmosphere.
 A meteor shower happens when
Earth passes through the orbit of
comets

8. meteoroid
 A meteoroid is a fragment of
comet, an asteroid, moon or even
mars.
 A meteoroid is the space rock
fragments before it enter to earth
atmosphere.

9. meteorites
 When a meteoroids or part of
meteoroids survive passing
through Earth atmosphere, an
land on Earth surface.
