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

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 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.

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.
