In the article Odds of Finding Earth-Size Exoplanets Are 1-in-4 they talked about how they conducted there study about looking at stars with and without planets. In this study the stars that were examined were 120,000 stars in the Hipparcos Catalog. The study was to examine how many stars have planets orbiting. The study was using interments to see how much the sun wobbles when the planet moves around the star and interments to record to blink when the planet pass through the sun’s light. Using the information gathered from the interments they were able to calculate the distance and the mass of the planets. When they were looking at the stars with planets they found that there were a lot of earth mass planets near the sun. The planets are about 4 times closer to there star than the earth is to the sun. This was recorded at most of the suns that have planets around them. Scene earth mass planets are more common further from the star than the ones found they predict that one in four sun like stars are probably hosting earth size planets.
I think this is important because to find other planets that may host life is extraordinary and beneficial to the understanding how life works. This also led to a habitable planet, so one day we may go research or live on a new world. With every day I think its important to find new also because to see its past life's which I think is amazing in every way. To understand and what makes a planet have possible life is one of the best uses of astronomy. This is very valuable in the field because there is a far better chance of finding an exoplanet one that is similar in the earth in many ways.
