SCOTT GAUDI To begin a discussion about how likely another planet is to resemble that of earth, we must first take a look at the bigger picture. Our solar system will tell us a lot about the likely hood of another system having a planet like our own. On January 5 th , 2010 Scott Gaudi of Microlensing Follow-Up Network (MicroFUN) found a mathematical way to calculate how common our solar system might be to those found in the galaxy. In his thesis, Gaudi originally suggested that 45 percent of stars in the galaxy are holding planets that resemble that of our own. A new calculation of 15 percent was found by using a method called gravitational microlensing, which detects objects in space ranging from planets to stars regardless of the light they emit. Before this phenomenon was found, astronomers were only able to detect these planets or stars if they emitted massive amounts of light. The gravitational lens effect is the reason Gaudi and MicroFUN were able to come up with this value, and this is how they did it. When a distant star or object
