2. Solar System
The solar system is made up of the
sun, its
planets, asteroids, meteoroids, and
comets. Each of these bodies are
held to each other by the force of
gravity.

4. Sun
• A star that is the basis of the solar system and
that sustains life on Earth, being the source of heat
and light.
• It is about 865,000 miles in diameter.
• Its mass is almost 700 times the total mass of all
the bodies in the solar system and 332,000 times
that of the earth.
7. Mercury
•
•
•
•
•
•
the nearest planet to the sun
36 million miles (58 million km) from the sun
takes 88 days for Mercury to orbit the Sun
3,000 miles or 4,800 km diameter
59 days rotation of axis
800 degrees Fahrenheit or 450 degrees Celsius
temperature
9. Venus
• second planet from the sun
• 67 million miles or 107 million km from the
sun
• 225 days to orbit around the sun
• 243 days rotation of axis
• The cloud layer holds in the heat and keeps the
planet much hotter than the earth.
11. Earth
•
•
•
•
the third planet from the sun
93 million miles from the sun
7,926 miles or 12,760 kilometers diameter
surrounded by a band of gases called the
atmosphere which is mostly nitrogen and oxygen.
• 24 hours or 1 day axis rotation
• 365 1/4 days revolution
13. Mars
• fourth planet from the sun
• 4,200 miles or 6,800 km in diameter and just over
half the diameter of the earth
• has a very thin atmosphere made up of carbon
dioxide, with some nitrogen and argon
• red in appearance due to oxides in its crust
• 80 degrees Fahrenheit or 27 degrees Celsius
temperature
14. • 141 million miles 228 million kilometers
from the sun
• orbits the sun in 687 days
• 24 hours or 1 day rotation
• hot spots under the crust
16. Jupiter
• fifth planet from the sun and largest planet of
the solar system
• 484 million miles or 778 million kilometers from
the sun
• orbits the sun every 12 years
• Its mass is 318 times that of the earth and
about 2 1/2 times the mass of all other planets
combined.
17. • The atmosphere of Jupiter is made up
mostly of hydrogen, helium, methane, and
ammonia
• Jupiter has no solid rock surface
• 10 hours axis rotation
19. Saturn
• sixth planet from the sun and second largest
planet
• 886 million miles or 1.43 billion kilometers
from the sun
• 29 1/2 years to orbit or revolve around the sun
• covered with a thick atmosphere made up of
hydrogen and helium
22. Uranus
• seventh planet from the sun
• 1.78 billion miles or 2.87 billion kilometers
from the sun
• orbits the sun every 84 years
• 32,000 miles or 47,000 kilometers diameter
• weight is about 15 times that of the earth
23. • has a thick atmosphere of hydrogen, helium, and
methane
• has a thick atmosphere of hydrogen, helium, and
methane
• 18 hours axis rotation
• 330 degrees Fahrenheit or -200 degrees Celsius
temperature
• has 11 rings
25. Neptune
• eighth and currently the last planet of solar
system
• 3 billion miles or 4.5 billion kilometers from
the sun
• orbits the sun about 165 years
• 30,700 miles or 49,000 kilometers diameter
• Its mass is about 17 times the earth's mass
26. • It is much like Uranus as it has a thick
atmosphere of hydrogen, helium, methane, and
ammonia and a rapid period of rotation
• atmosphere has zones like Jupiter's and giant
storm systems that look like dark spots on its
surface
• has a ring system made up of three bands.
28. Asteroids
• small, airless rocky world revolving around the
sun
• Too small to be called planets
• the mass of all the asteroids is the mass of all
the asteroids is less than that of Earth's moon.
• Most asteroids lie in a vast ring between the
orbits of Most asteroids lie in a vast ring
between the orbits of Mars and Jupiter
29.
30. Meteoroids
• small bodies that travel through space
• smaller than asteroids and just a size of a
pebble
• Most meteoroids come from asteroids that
are broken apart by impacts with other
asteroids
32. Comets
• is an icy body that releases gas or dust
• contain dust, ice, carbon dioxide, ammonia, methane and
more
• As a comet gets closer to the sun, the ice on the surface of
the nucleus begins turning into gas, forming a cloud known
as the coma.
• Radiation from the sun pushes dust particles away from
the coma, forming a dust tail, while charged particles
from the sun convert some of the comet's gases into
ions, forming an ion tail.
