2 PLANETS OMG OMG Planets

3 Let’s learn about planets!
Our solar system began as a big nebula (cloud of 99% gas and 1% dust) that collapsed. Our sun (star) was made from the center of the nebula, and other gas and dust spun off and away, cooling into planetesimals (early, still-forming planets) and other space junk. As the space junk and planetesimals spun off, they often created their own gravitational pulls. They cooled and collected nearby debris (from crashing into one another) and became planets.

5 Yay great so what does that mean now so what who cares
Well, it resulted in our planets. From the sun, we have Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune
