2. INVENTION
Who invented the solar system?
The solar system was formed from a massive gas cloud, and
layouts were observed and refined beginning in the sixth
century B.C.E. by early Greek astronomers. Nicholas
Copernicus and Galileo Galilei continued observing the solar
system well into the Renaissance era
In 200 B.C.E, Greek astronomer Aristarchus invented a model
of the solar system in which the sun was in the middle and
the planets rotated around it. ystem well into the
Renaissance era

3. Our Solar System

4. #The Solar System is the sun together with the eight planets and all
other celestial bodies that orbit the sun.
#Everything in the Solar System orbits or revolves around the Sun in a
counter-clockwise direction.
#The Sun contains around 98% of all the material in the Solar System
#The Solar System is estimated to have formed between 4.53 and 4.58
billion years ago.

5. MERCURY
 Closest to the sun
 Smallest planet
 Rotates once every 59 earth days.
 One day on Mercury lasts 176 Earth days.
 Very dry, hot, and almost airless

6. VENUS
Second
closest
planet to the
sun
Brightest
celestial
body besides
the moon
and sun.
Cannot be
seen in the
middle of the
night
Can be
observed in
the east at
sunrise

7. EARTH
3rd from
the sun
5th largest
planet in
the solar
system
More than
4.5 billion
years old
Has one
natural
satellite
we call the
moon.

8. MARS
Fourth from the sun
Only planet whose surface can
be seen in detail from the Earth
Reddish in color, the atmosphere of
Mars is made of carbon dioxide

9. JUPITER
The Fifth planet from the sun
Largest planet in the solar system
Has at least 39 months

10. SATURN
Sixth planet from the sun
Has at least 31 moons
The surface on Saturn consists
of liquid and gas

11. URANUS
Seventh planet from the sun
1st planet discovered with a telescope
Atmosphere is a mixture of Hydrogen,
Helium, and methane
Does not have a solid surface

12. NEPTUNE
8th and farthest planet from the sun
The atmosphere is mostly hydrogen and helium
Has 8 known moons

13. SUN
Located 93,000,000 miles from Earth
Closest star to Earth
At least 4.5 billion years old
Has a surface temperature of 10,000 degrees and
a center temperature of 27,000,000 degrees Fahrenheit.

14. MOON
Bigger than Pluto
Only object in the Solar System visited by
humans.
A lunar month is 29.35 days,
1 new moon to the next.
The moon’s gravitational pull
on Earth is the main cause of
the ocean’s tide.

15. ALTHOUGH WE TEND TO THINK ONLY ABOUT THE SUN AND THE
PLANETS WHEN WE CONSIDER OUR SOLAR SYSTEM, THERE ARE MANY
OTHER TYPES OF BODIES THAT HUDDLE AROUND THE SUN ALONG WITH
EARTH AND ITS PLANETARY BROTHERS AND SISTERS. THE SOLAR
SYSTEM INCLUDES MOONS (AND SOME OF THOSE MOONS HAVE MOONS),
SUPERNOVA EXPLOSIONS, COMETS, METEORS, ASTEROIDS, AND PLAIN
OLD SPACE DUST. TO BE SURE, THERE ARE MORE OBJECTS IN OUR
SOLAR SYSTEM, SOME OF WHICH HAVE YET TO BE DISCOVERED.
WHAT ELSE IS IN OUR SOLAR SYSTEM?

16. ASTEROIDS
The Asteroid Belt is the space between Mars and Jupiter
It contains irregularly shaped chunks of debris called
asteroids
Asteroids made of rock and metal. Mostly nickel and iron

17. COMITS
1.A comet is an icy small Solar System body that, when
passing close to the sun, heats up and begins to outgas,
displaying a visible atmosphere or coma, and sometimes
also a tail.
2. Comets usually have highly eccentric elliptical orbits, and
they have a wide range of orbital periods, ranging from
several years to potentially several millions of years.
