Science Project#2 (Solar System)

Solar system: The sun and the objects that are traveling around it.


Introduction: Our sun is a star similar to other stars in the night sky. It appears so large and bright to us because it is much closer to Earth. The objects around the sun include eight planets. Planets are objects that travel around a star in a path.

PLANETS

1.Mercury: Mercury is the closer planet to the sun and the time for complete spin in Earth hours or days is of 59 days.




2.Venus: Venus is the second closer planet to the sun and the time for complete spin in Earth days or hours is of 243 days.


3.Earth: Is the third planet in the solar system and is the only planet that can allow life and the time to complete the spin in Earth days or hours is of 24 hours.


4.Mars: Is the fourth planet in the solar system and is one of the farter planets of the sun and the time for complete spin in Earth days or hours is of 24 1/2 hours.



5.Jupiter: Is the fifth planet in the solar system and is farter than Mars of the sun and for complete spin in Earth hours or days is of 9 hours 56 minutes.



6. Saturn: Is the six planet in the solar system and is more far away of the sun than Mars and Jupiter and the time for complete spin in Earth hours or days is of 10 hours 40 minutes.



7. Uranus: Is the number seven planet in our solar system and is more far away than Mars,Jupiter and Saturn. The time for complete spin in Earth hours or days is of 17 hours 14 minutes.



8.Neptune: Is the last planet in the solar system and is the most far away planet of all and the time for complete spin in Earth hours or days is of 16 hours 6 minutes.



Conclusion: In my conclusion I think that all the planets are different for example Earth. I take Earth for example because is the only planet can allow life.
