32. PLANET FACTS
Mercury
Fact 1: Mercury is the closest planet to the sun and the fastest
moving planet in the Solar system.
Fact 2: Mercury is a hot and rocky planet. During the day time
it is hotter than an oven, during the night time it is colder than a
freezer.
Fact 3: There are lots of craters on Mercury. Its surface looks
similar to the surface of our moon.
Fact 4: Mercury has no moons.
Venus
Fact 1: Venus is the second planet from the sun. It is the
hottest planet in the Solar system.
Fact 2: Venus is covered with fast-moving sulphuric acid clouds
that trap heat from the sun.
33. Fact 3: Venus turns slowly. Each day on Venus takes 243 Earth
days.
Fact 4: Venus has no moons.
Earth
Fact 1: Earth is the third planet from the sun. It is the planet
we live on and the only planet in the Solar system that is known to
support life.
Fact 2: Earth is the 5th largest planet in the Solar system.
Fact 3: The earth is made up of 75% (three quarters) water.
This is the main reason why Earth can support life (See Qur’an).
Fact 4: Earth has one moon.
Mars
Fact 1: Mars is the fourth planet from the sun. Mars is red
because it is covered with rust (iron oxide). Rust forms when iron
mixes with small amounts of oxygen and water.
Fact 2: Mars is a dry rocky planet with ice caps at its north and
south poles like Earth.
34. Fact 3: The largest volcano in the solar system is on Mars. It is
called Mount Olympus. It is 17 miles tall and 320 miles wide.
Fact 4: Mars has 2 tiny moons called Phobos and Deimus.
Jupiter
Fact 1: Jupiter is the fifth and largest planet. It is mostly
made of gas and some liquids. There are no seasons on the planet
Jupiter.
Fact 2: There is a large red spot on Jupiter. This is a raging
storm. The Earth is the same size as Jupiter’s red spot.
Fact 3: Jupiter is so big that all the other planets could fit
inside it.
Fact 4: Jupiter has 39 moons so far.
Saturn
Fact 1: Saturn is the 6th planet from the Sun. It is the 2nd
largest planet in our solar system. It has rings made of ice and
dust particles
35. Fact 2: We can see Saturn with a telescope but we need a small
telescope to see its rings.
Fact 3: Saturn looks like it has stripes because it is made of
different gases. Some of the gases do not mix and when Saturn
spins, high winds blow the gases into stripes.
Fact 4: Saturn has 33 moons so far. Titan is the largest moon.
Uranus
Fact 1: Uranus is the seventh planet from the sun. It is a large,
icy planet covered in clouds. Uranus is blue because of the methane
gas in its atmosphere.
Fact 2: Uranus is the third largest planet in the Solar System.
Uranus has extreme seasons with extremely dark and cold years
followed by extremely hot years.
Fact 3: Uranus has a thin belt of 11 rings made up of rock and
dust.
Fact 4: Uranus has 22 known moons. Oberon is the largest moon.
Neptune
Fact 1: Neptune is the 8th planet from the Sun. It is the 4th
largest planet in our solar system. Neptune is covered in clouds and
is blue because of Methane gas in its atmosphere.
36. Fact 2: Neptune also has a storm much like Jupitor. Neptune’s
storm is called its Great Dark Spot
Fact 3: Neptune also has rings. These rings are made up of dark
rock and dust. One of the rings even has a twist in it.
Fact 4: Neptune has 13 moons so far. Triton is the largest
moon.
Pluto
Fact 1: Pluto is not really a planet. It is called a dwarf planet.
There are many dwarf planets in our Solar System. Pluto is smaller
than many of the moons in the Solar System, including our own
moon.
Fact 2: Pluto is an extremely cold planet because it is so far
away from the sun. From Pluto the sun would look like a tiny dot in
the sky.
Fact 3: Nobody really knows what Pluto is made of although
scientists think it is probably 70% rock and 30% water.
Fact 4: Pluto has one large moon and two tiny moons.
