NASA Vs Exoplanets

NASA has found many planets out of our solar system. Those planets are called exoplanets. In addition,Nasa has confirmed 3,397 exoplanets And also 2,531 other solar systems. NASA has launched a telescope into space and it is called spitzer. Therefore, using the spitzer telescope to find a lot more exoplanets. There is a lot of exoplanets outside our solar system and NASA plans to find a lot more.

Some astronomers say that people may be able to live on other planets that are the same size as earth. In addition,Two of the three planets are very close to the star and it takes two to three earth days to orbit the star, and the third planet can take from 4 days to 73 days to orbit the star. Scientist look for forms of life on the planet by seeing gas, liquid, etc. The three planets were found because of a telescope that the scientist used. Using the telescope, they could see it from earth when a planet passes the ultra cool dwarf star. It appears to dim the star a little bit and that’s how that’s how they see the three planets from earth.
Finding planets that we can live on is good for a variety of reasons.One reason is that if something happens to earth we can have another planet to live on.
For instance, if earth would explode than we would be able live somewhere else. Another reason is that we could spread the population to other planets.Finally we could learn more about the planets that we live on.For example, if we found a way to live on mars we could learn about the planet
mars.
