planet measurements
Planet Measurements
  • Mass: 6.4169x10 23
  • Volume: 1.63116x1011km3
  • Density: 3.934g/cm3

Float or sink?

Sink, because the density is heaver for it to float

  • Gravity: 3.71 m/s2

Q. What is your composition of the atmosphere of your planet? Is it a thick or a thin atmosphere?

A. Carbon Dioxide, Nitrogen, Argon. It is a thin Atmosphere


Order from the sun: 4th from the sun

Distance from the sun in Km: 2.2x108km

Distance from the earth in Km: 54.6 million Km

orbit and rotation
Orbit and Rotation

Q. How long does it take for your planet to orbit the sun?

  • 1.88 Earth years

Q. How long does it take for your planet to rotate on its own axis?

A. 24.622.9

t emperature

Q. What is the temperature range on your planet?

A. 218 k ( -55c , -67F)

composition appearance

Q. What type of planet is it( rocky or a gas giant)? How does this describe the planet’s surface composition?

  • Rocky, its puts the picture of dirt and dry surface.

Q. What is the internal composition?

  • Dense core, molten rocky mantle

Q. What does your planet look like?

  • Referred to as the red planet, canyons, volcanoes. It has water ice clouds hanging above the tharsis volcanoes. Its half the size of earth, dry and has a rocky surface.

No Rings


Q. What forms of water are found on Mars?

  • Ice, vapor

North Pole- ice cap

South Pole- no bodies of water because of atmosphere pressure

  • Stormy thunder
  • Chill Atmosphere
  • Clouds of water ice winds- up to 50 mph
  • Cold- drop to -100
  • Poles- -200
m oons

Q. Is their any moons on your planet?

  • yes, 2 moons
  • phobos- Asaph Hall – August 1877
  • Deimos- Asaph Hall – August 12, 1877

Human to planet??

Q. On your Planet, would a person choke in the atmosphere, be squashed be the extreme gravity, float with ease, freeze, burn up, or something else?

A. If people traveled to Mars they would freeze, float really high- gravity(low) and your lungs would pop.
