What is the Universe?
What is the solar system?
The Sun
 The Sun is a yellow
dwarf star.
 It is believed to be over
4 billion years old.
 It is nearly 99% of the
galaxy mass.
The Moon
 The Moon is the Earth's
only natural satellite
and the fifth largest
satellite in the Solar
System!
 The Moon is like a
desert.
 The Moon travels
around the Earth in an
oval shaped orbit.
Meteorites
 Meteoroid is a piece of
stone-like or metal-like
debris which travels in
outer space.
 Very bright meteors
are known as fireballs.
 A small number of
meteorites have been
shown to be of Lunar
(23 finds) or Martian
(22) origin.
Stars
 Stars formed from gas-
dust environment as a
result of gravitational
compression.
 The temperature in the
center of the star is
around 10-12 million
Kelvin.
 There are different
groups of stars: Red
Dwarfs, Yellow Stars,
Blue Giants.
Asteroids
The Asteroid Belt
 An asteroid is a bit of
rock.
 Most of the asteroids in
our solar system can be
found orbiting the Sun
between the orbits of
Mars and Jupiter.
 Asteroids can be a few
feet to several hundred
miles wide.
The Dwarf Planets
Comets
 A comet's tail can be
millions of kilometers
in length.
 About 100,000 million
comets orbit the Sun.
 What seems to be light
from the comet is
actually a reflection of
our Sun's light.
Why do we explore space?
To sum up
Our planet is one of the
unique planets in the huge
universe.
