This document outlines the objectives and key facts about the solar system. It aims to compare the inner and outer planets by looking at their position relative to the sun, composition, similarities and differences. The inner planets are Mercury, Venus, Earth, and Mars. They are smaller and closer to the sun. The outer planets are Jupiter, Saturn, Uranus and Neptune. They are larger, further from the sun, and have faster orbit and spin speeds. The document also notes that Earth is the third planet from the sun and the only planet known to support human life.

2. Objectives of this project:
• To look on the Solar System.
•The difference and similarities between the outer and
inner planets.
•The position of the sun

3. Definitions of the Solar System
The Solar System is made up of eight (8) planets orbiting the sun. In
addition to planets it also consist of moons, comets, asteroids ,
meteoroids, minor planets dust and gas.
The sun contains 98% of the material in the solar system, it is also
the largest object within the Solar System.

5. The Inner planets
There are four inner planets within the Solar System,
which are said to be closet to the sun:
 Mercury
 Venus
 Earth
 Jupiter

7.  This is the second planet away from the sun
 Venus has a thick atmosphere that making it difficult
for modern scientist to penetrate. But recently
scientist has made a break through in peeking through
the cloud to view its surface
 It is covered with craters, volcanoes and mountains
 The brightest planet within the solar system looking
like a bright star.

8.  The third planet away from the sun.
 Earth has one moon.
 The atmosphere is made up of composed oxygen
(21%), nitrogen (78%) and other gas.
 Earth has an oblate spheroid shape, bulging of the
equator and flattened at the poles.
 By estimation earth is 4.5 million years old.
 Its temperature , atmosphere , weather and other
factors make it suitable for human beings to live

11. Difference and similarities between
inner and outer planet
Similarities:
1)they are all larger than the earths moon.
2) they are all within a 30 astronomical unit (AU)
radius of the sun.
3) they are positioned between the asteroids belt and
the sun.

12. Differences between the outer
planets
1)They are further away from the sun, larger in size and lies
outside the asteroids belt. These planets are different in
many ways such as:
2)The inner planets spins very quickly. The different in speed
is so noticeable, for example as if you were in Jupiter your
days would be 9 hours and 55 minutes long, while if u were
in Venus you would have to wait 243 hours for the
equivalent earths day to pass.
3)Spin Speed
4)Sun orbit rate

13. The Outer planets

14. Jupiter

15. Saturn
 The second largest planet.
 Saturn is made up of hydrogen and helium the two(2)
most lightest gas making Saturn the lightest planet.
 Saturn is most known for its rings.
 Has 53 official moon and 9 provisional one.
 It takes 46 earth days for Saturn to orbit around the
sun.
 It has nine (9) band of rings.

16. Uranus

17. Neptune
 8th planet from the sun.
 4th largest in diameter.
 Neptune orbit the sun every 165 years.
 It was discovered on September 23,1846 by Johann
Galle and Heinen, D’ Arrest
 Neptune was visited by a spacecraft voyager 2 on
August 25,1989
 Has 13 moon.
 It has six rings that circle the planet.
