1. SOLAR SYSTEM

2. SOLAR
SYSTEM
• The solar system is made up of the sun and everything
that orbits around it, including planets, moons, asteroids,
comets and meteoroids.
• It extends from the sun, called Sol by the ancient Romans,
and goes past the four inner planets, through the Asteroid
Belt to the four gas giants and on to the disk-shaped
Kuiper Belt and far beyond to the teardrop-shaped
heliopause.
• Scientists estimate that the edge of the solar system is
about 9 billion miles (15 billion kilometers) from the sun.

4. THE SUN

5. THE SUN
• The sun is by far the largest object in our solar
system.
• Containing 99.8 percent of the solar system's
mass.
• It sheds most of the heat and light that makes
life possible on Earth and possibly elsewhere.
• Planets orbit the sun in oval-shaped paths called
ellipses, with the sun slightly off-center of each
ellipse.

6. MERCURY

7. MERCURY
• Mercury is the closest
planet to the sun but,
perhaps surprisingly, it
does not have the highest
temperatures.
• It is the second densest
planet of the Solar System,
but also the smallest
planet.
• The structure of Mercury
makes it the most similar
planet to Earth.

8. VENUS

9. VENUS
• Venus is hotter than Mercury despite being
further away from the Sun.
• A day on Venus is longer than a year.
• Its temperature is 462°C.
• Unlike the other planets in our solar system,
Venus spins clockwise on its axis.
• Venus is the second brightest natural object
in the night sky after the Moon.

10. EARTH

11. EARTH
• Earth, our home, is the third planet from the
sun.
• It's the only planet known to have an
atmosphere containing free oxygen, oceans of
water on its surface and, of course, life.
• Earth has a diameter of roughly 8,000 miles
(13,000 kilometers) and is round because gravity
pulls matter into a ball.
• Average distance from the sun is 92,956,050
miles(149,598,262km)

12. MARS

13. MARS
• Mars is the fourth planet from the Sun and the
second-smallest planet in the Solar System.
• It’s called the Red Planet because its iron-rich
dust gives it landscape a rusty-red color.
• Mars’s gravity is 38 percent of Earth’s. So if you
weigh 60 pounds here, you’d weigh about 23
pounds there.
• A Martian day is about 40 minutes longer than a
day on Earth.

14. JUPITER

15. JUPITER
• Jupiter is the fifth planet from the Sun and
the largest in the Solar System.
• Jupiter is the fourth brightest object in the
solar system.
• Jupiter has the shortest day of all the planets.
It turns on its axis once every 9 hours and 55
minutes
• Jupiter’s moon Ganymede is the largest
moon in the solar system.

16. SATURN

17. SATURN
• Saturn is the sixth planet
• from the Sun and the
• second-largest in the Solar
• System, after Jupiter.
• Saturn is the least dense planet in the Solar System.
• Saturn has 62 moons.
• The length of the day on saturn was a mystery until
recent.

18. URANUS

19. URANUS
• Uranus was officially discovered by Sir
William Herschel in 1781.
• Uranus makes one trip around the Sun every
84 Earth years.
• Uranus is often referred to as an “ice giant”
planet.
• Uranus hits the coldest temperatures of any
planet With minimum atmospheric
temperature of -224°C.

20. NEPTUNE

21. NEPTUNE
• Neptune is the most distant planet from the
Sun.
• Neptune is the smallest gas giant.
• A year on Neptune lasts 165 Earth years.
• Neptune is named after the Roman god of
the sea.
• Neptune has 6 faint rings
• Neptune spins on its axis very rapidly.
• Neptune has 14 moons.
