Other Worlds We had a guest speaker come and visit our school today. He was an astronomer who taught us about other worlds. His name was Mr. Gianforte. Mr. Gianforte told us that there were almost five hundred exoplanets already discovered. An exoplanet is a planet outside of our solar system. He also taught us that on September 29, 2010 they announced that a goldilocks (planet that is not too hot, not too cold) planet was discovered. It is the most earthly planet we've discovered yet.
We learned two ways to find planets. One was the radial velocity method. This means the planet passes in front of the star, therefore causing the light to be different colors. Another way was planetary transit method. This is when the planet passes in front of the star causing the amount of light to go down. That is what we learned.
