Our Solar SystemBy Jiwon Park

This is Why I am Interested in Planets

The reason I picked planets for my research is because I always have been interested in it . And I like to look at them and study about them.

This is What I Learned

Through This ProcessTo create my passion project I had to

write all the facts about planets. The most challenging thing I did was that I had to write facts about all the planets in our Solar System. So I had to learn and study about them.

This is What This is Going to Help me DoWhen I grow up I want to be a scientist and a astronaut so this is going to help me learn what astronauts and scientists do.

This is the Color and the Names of Planets

Mercury-gray Venus-orange and black Earth-white, brown and green Mars-red, white and black Jupiter-yellow and orange Saturn-orange and blackUranus-sky blueNeptune-dark blue

This is How and Why People Study Planets

People study about the Solar System and space. They use radio telescopes and space probes to learn about space and planets. The astronomers have to get trained to understand the information that are gathered by the telescopes. Astronauts make space shuttles, rockets and more. Astronauts use the space probes to collect information about space and planets. Through these, they learn how the eight planets move and spin.
