As the globe spun around this made everything in sky rotate around the earth. How-ever a scientist by the name of nicholas coperncus noticed that planets and stars seemed to move across the night sky in one direction half of the year and then move in the complete opposite direction the other half of the year. The only way for things in the sky to change direction, is if the earth is going around the sun. • Galileo's Galilei also provided evidence the earth is going around the sun when he noticed Jupiter's moons where going around Jupiter. He also observed phases on the planet Venus just like those on the moon. The only way for Venus to have phases is if Venus is going around the sun like the moons going around Jupiter. • The sun is a massive star and that mass comes with a lot of gravitational attraction. So much gravitational attraction that the suns gravity can hold planets in orbit beyond Neptune's distance of 4.5 billion kms. Just like how the cup spinning around was able to suspend the paint can in mid air, planets gong around the sun also have velocity. In fact Earth is going around the sun at 100,000kms every hour. This velocity balances out the force of gravity pulling on the planets keeping the planters spinning around the sun. • • !!!CENTRIPETAL FORCE EXPERIMENT!!!
