The nine planets in our solar system

Done by: Paul Choi 8b

Mercury

• Mercury does not have an atmosphere around itself, which means there are no elements around it.

• Mercury’s surface was shaped by impact cratering, which is when objects from space hits it’s surface.

• Volcanism, where the lava flooded the surface of Mercury

• Finally, the tectonic plates

Venus

• The reason why it’s called the evening star is because it can be seen most clearly on Earth

• You can find Co2 and sulfuric acid in the atmosphere• “retrograde” is when Venus is rotating clockwise unlike all the

other 7 planets• The rotation takes 243 days and the revolution takes 225 days• If u were on Venus, then the sun would rise form the west

and it would set in the east because it rotates clockwise• Venus is also known as the hottest planet in our solar system

because the thick atmosphere traps all the heat from the sun and doesn’t let it out

Earth

• Our atmosphere is composed of O2, nitrogen, argon, and water vapor,CO2neon, methane, krypton, helium, xenon, hydrogen, nitrous oxide, carbon monoxide, nitrogen dioxide, sulfur dioxide, and ozone

• The rotational tilt of the earth is 23.5 degrees• The boiling core creates the magnetic field around Earth• The only satellite of the Earth is our moon

Mars

• Some particles of meteorites on earth are from mars and ancient bacteria might have existed on mars

• The primary element in the Mars’s atmosphere is carbon dioxide

• The surface of mars appears to be red because it’s rich in iron

• The Olympic moons is the largest volcano in the solar system

• Mars have 2 satellites called Phobos and Deimos

Jupiter

• The speed of it’s rotation make the poles flat and the a bit bulgy on the equator

• The Atmosphere of Jupiter is made of hydrogen, helium, sulfur, and nitrogen.

• The great red spot is a gigantic hurricane storm• So far, Jupiter has about 50 satellites• IO is special because it is still volcanically active

Saturn

• The atmosphere is made of helium and hydrogen

• Some say the rings were formed by the break down of its satellites

• The rings are composed of dust and ice.• Saturn has the lowest density out of all the

planets so it can float on water

Uranus

• Uranus has a special rotational axis because it’s tilted 98 degrees

• Its atmosphere is composed of helium, hydrogen, and, methane

• It has about 27 known satellites

Neptune

• The atmosphere is composed of ammonia, helium, and methane

• So far, it is known to have 13 satellites• Triton is the largest satellite of Neptune,

however due to it's retrograde rotation and it’s density and composition, many believe it wasn’t a natural satellite of Neptune

Pluto

• Pluto has three natural satellites called Charon, Hydra, and Nix

• Through the spectroscope, scientists have learned that Pluto has methane frost and water frost on Charon.

• Charon is more blue in color than Pluto because it’s atmosphere condenses and falls on its surface when Pluto is farthest from the sun

Ceres

• It takes about 4.6 years for Ceres to fully revolve around our sun

• It used to be mistaken as an asteroid because it was revolving the sun in the asteroid belt

• On its surface, there would be water ice, clay, and, carbonates

Eris

• It used to be called Xena before it was properly named

• It takes Eris approximately 557 years to finish a single revolution around the sun

• It has one moon named Dysnomia• Eris is not defined as a planet because it

doesn’t have a clear orbit

The end!!!!
