The document provides information about the planets in our solar system as well as other celestial bodies such as comets, asteroids, meteors, and meteorites. It details facts about each planet such as their size, composition, orbital period, temperature, and other characteristics. It also describes comets as icy bodies that develop tails when near the sun, asteroids as rocky fragments in the asteroid belt, meteors as space rocks that burn up in the atmosphere appearing as shooting stars, and meteorites as chunks of rock or metal that reach the ground.
4. • Mercury is the planet nearest
to the sun it has no moons.
• If you weigh 100 pounds on
Earth, you would only weigh 37
pounds on Mercury.
• It takes less than 88 Earth
days for Mercury to orbit
around the sun.
• 1 day lasts about 180 Earth
days.
• The temperature rises above
800°F while on the dark side it
falls rapidly to -300°F.
Mercury
5. • Venus, Second Planet from the
Sun, Brightest Planet in Solar
System.
• Venus is known as Earth’s twin
sister because of its similar
size and proximity to each
other.
• Venus has a longer day than
year.
• It takes 243 days for Venus to
make a rotation.
• And it takes 224 days for
Venus
6. • The Earth is estimated to be
4.5 billion years old.
• It travels through space at
660,000 miles per hour.
• The Earth weighs 6,588 10
21 tons.
• The world is not round. It is
an oblate spheroid, flattened
at the poles and bulging at the
equator.
Earth (Our Home)
7. • Mars is the 4th closest planet to
the sun. It can easily be seen
from Earth .
• Mars is red because it is rusty.
There is a lot of iron in the
soil, and the air on Mars has
made it turn red.
• Mars orbits the sun every 687
Earth days.
• The Martian “day” is about half
a hour longer than Earth.
• In winter, nighttime
temperature can drop as low as
-191°F.
Mars
8. • Jupiter is the largest planet in
our Solar System.
• Jupiter's volume is large
enough to contain 1,300 planets
the size of Earth.
• Jupiter rotates faster than any
planet in the Solar System. It
rotates so quickly that the days
are only 10 hours long.
• But it takes 12 Earth years for
Jupiter to complete an orbit
around the sun.
• If you weigh 100 pounds on
Earth, you would weigh 264
pounds on Jupiter.
Jupiter
9. • Saturn is the 2nd largest planet.
Only Jupiter is larger. Saturn has 07
thin, flat rings around it.
• The planet can be seen from Earth
with the unaided eye, but its rings
cannot.
• It is so light that it could actually
float on water if there was an ocean
big enough to hold it.
• It takes about 29.46 Earth Years for
Saturn to orbit around our sun.
• Saturn's rings are made up of billions
of pieces of rocks and dust.
• Saturn is a giant ball of gas, but it
does have a solid inner core.
• A 100 pound object on Earth would
Saturn
10. • Uranus is the 7th planet from the sun.
• Because of the strange way it spins,
nights on some parts of Uranus can last
for more than 40 years.
• The planet's most extraordinary
feature is the tilt of its rotational axis,
which is almost perpendicular to the
plane of the ecliptic, which means that
it alternately has its north pole and its
south pole turned towards the sun.
• Uranus is the coldest planet in the solar
system.
• Uranus and Neptune are both known as
Ice Giants.
• It takes 30,685 Earth days for Uranus
Uranus
11. • Neptune is so far away that it
took the space probe Voyager
2, 12 years to reach it.
• Neptune is the stormiest
planet. The winds there can
blow up to 1,240 miles per
hour, that is three times as
fast as Earth's Hurricanes.
• Neptune is a sea blue color due
to the methane gas in its
atmosphere.
• Neptune has 8 known moons.
• Neptune is 30 times farther
from the sun as is the Earth.
• It goes around the sun once
every 165 Earth Years.
Neptune
12. Comets
Comet is a ball of Ice and dust that makes a tail when
it approaches.
Comets are also leftovers from when the universe was
made.
All comets have nucleus, that is the ice, dust, and rock
in the comet.
When the comet approaches the sun, the solar energy
melts the ice and vaporize. The gas form the comet
make the tail.
The gas also makes a cloud all over the comet called a
13. Asteroi
ds
An Asteroid is a small rocky object that is in the
solar system.
Many of the asteroids in the solar system in orbiting
the sun between Mars and Jupiter called the asteroid
belt.
Asteroids are rocky fragments left over from the
formation of the solar system about 4.6 billion years
ago.
14. Meteor
• A meteor is a small ball of light that appears in the
night sky briefly.
• It is also called Shooting star.
• Some wish a pone the meteor and make a wish.
• It is said that if you wish on a shooting star your
wish will come true.
• The meteoroid when it falls down into the earth
atmosphere it burns up into a meteor or a shooting
star.
15. Meteori
te
• A meteorite is a small chunk of metal or rock that falls
down to earth or any other planet.
• An iron meteorite weighing some 60,000 kg is the
largest meteorite ever found. It still lies where it was
found in 1920 at Hoba Farm, near Grootfontein,
Namibia. Surprisingly, there is no crater, because the
meteorite entered the atmosphere at a long, shallow
angle and was slowed down by the atmospheric drag.
