The planets in the Solar System
By: Virginia
SpeirsSlide2
The Solar System
The solar system is made up of many different things
There are 8 planets in our solar systemSlide3
The Inner Planets
The inner planets are the four planets closest to the sun. The inner planets are - Mercury, Venus, Earth,
and Mars
.
Mercury- completes its orbit around the sun every 88 days.
Venus- has no moons.
Earth- has an atmosphere made up of 78% nitrogen, 21% oxygen, and 1% of other gases.
Mars- like Earth, has seasons, polar ice caps, and weather. There is evidence on mars that there was once water and maybe even life!Slide4
The Outer Planets
The outer planets are the five planets farthest from the sun. The outer planets are – Jupiter, Saturn, Uranus, Neptune , and Pluto.
Jupiter- is the biggest planet in our solar system. About 1400 earths can fit into Jupiter. Jupiter has 50 known moons.
Saturn- is mostly made of hydrogen and helium. Its volume is 755 times greater than earth.
Uranus- was discovered in 1781 by William Herschel it takes 84 earth years to complete one orbit
.
Neptune- takes 165 earth years to complete one orbit. It is nearly 4.5 kilometers from the sun.
Pluto- discovered in 1930. From earth it takes 9 ½ years to get to Pluto.Slide5
70% of earth’s surface is water
.
30% of earth’s surface is land.
All of earths five oceans include: the Atlantic , the Pacific, the Indian, the Arctic, and the Southern Ocean
The largest ocean is the pacific ocean. The smallest ocean is the arctic ocean.
Earth’s SurfaceSlide6
Earth’s surface
The human population on earth is approximately 7,039,101,305 as of September 2012.
There are 196 countries on earth.
Highest elevation on earth is Mt. Everest with 29,035 feet.
Earth is 4.5 to 4.6 billion years old.Slide7
Mars’s Surface
Scientist think that one of Mars's moons will one day crash into Mars.
Mars orbits the sun every 687 earth days.
Mars has the tallest volcano in he solar system, which is 15 miles high. That is 3 times taller than Mt. Everest!
Mars is red because of all the iron-oxide and rust that is in the soil of the planet.Slide8
Mars’s Surface
At its brightest, Mars outshines every other planet except Venus.
Hundred pound man would weigh 38 pounds on mars.
Valleys and canyons on mars prove that mars had once had water
On winter nights on mars, the temperature can some times drop as low as -191 degrees Slide9
Curiosity is a car-sized rover sent out to mars for exploration in August of 2012. Curiosity is now on mars and has found many new facts for research on earth. The rover’s main mission is to find out if mars once had been, or ever will be, suitable for life.

Things similar between
Earth and Mars
Earth
Mars
Earth, like mars, is an inner planet. Earth is the 3
rd
planet close to the sun.
Mars, like earth, has seasons and polar ice caps. Slide11
The difference between Earth and Mars
Earth
Mars
Earth has an atmosphere made of oxygen and nitrogen.
Earth’s surface is 70% water and 30% land.
Mars has a very thin atmosphere made up of carbon dioxide, nitrogen, and argon.
There is no water on mars, but there is evidence that there once was.Slide12
Conclusion
I have learned a lot more about space and science by doing this project. I learned more about all of the planets in our solar system; especially Mars. I hope this presentation helped you learn more too! Slide13
