TERRESTRIAL PLANETS
TERRESTRIAL PLANETS?
• First four planets in our solar system
(starting after the sun).
• Made up of mainly rocks and heavy
metals.
• Differ from gas giants in many ways.
• Smaller than gas giants.
• Have varied terrain (volcanoes,
mountains and craters)
• Have little to no moons.
• No planetary rings.
MERCURY
FACTS
• Mercury:
• Neighbors: It’s the closest planet to the sun, and its other neighbor is Venus.
• It’s the second densest planet.
• the temperature goes from -184 C to 427 C.
• it is the smallest planet in our solar system.
• Mercury is named after the Roman messenger of the gods
• a year on Mercury is 88 days on earth
• And Mercury has craters
VENUS
VENUS
• Neighbours: Earth and Mercury
• Venus turns the other way to most other planets
• it’s the hottest planet
• You can see Venus from Earth
• it is the brightest star in the sky at night
• Size: 12,104 km in diameter
FO SHIZZLE
EARTH
NEIGHBOURS
• The first four planets from the sun are all of the terrestrial planets.
Mercury is 77 million km from Earth
Venus is 261 million km from Earth.
Mars is 401 million km from Earth.
All of the distances can majorly vary and all of these are not 100% exact,
however they are what would be believed to be the furthest possible
distances from Earth.
SPECIAL FEATURES OF EARTH.
• Earth, of course, is the only planet we can be sure has life.
It has liquid water, plate tectonics, and an atmosphere that shelters it from
the worst of the sun's rays. But many scientists agree our planet's most special
feature might just be us.
How to stop
Global
Warming.
SIZE
• The diameter of the Earth at the equator is 12,756 km, and its circumference
or distance around the Earth at the equator is 40,075 km.
This is roughly similar compared to Earth as they are both Earth.
The diameter of the Earth at the equator is 12,756 km, and its circumference
or distance around the Earth at the equator is 40,075 km.
• Mars’ neighbours are: Earth and Jupiter.
• Mars is smaller than Earth.
• It is about half the size in diameter which is
about the size of all the landmass on Earth
• It has a diameter of approximately 6,790
km.
• This means it is just a little bit larger than
half the diameter of Earth (Approximately
12,750 km).
• Mars has a circumference of around
21,340 km from the equator.
• But from pole to pole it has a
circumference of around 21,240 km.
MARS
SPECIAL STUFF WE HAD TO ADD :P
• The “red” colour we see is from the large
deposits of iron that are spread
throughout the planet.
• The word “Mars” comes from the Roman
God of War.
• Pieces of Mars have fallen to Earth.
• On Mars, the sun appears smaller than it
does here on Earth.
• The Olympus Mons on Mars is the largest
mountain in our solar system. The
mountain itself is approximately 21km
high and reaches a whopping 600km in
diameter.
