Trappist-1 Research Paper

Satisfactory Essays
NASA discovered a system of seven Earth-size planets around a single star outside our solar system. All of these seven rocky planets could have water which is a key to life and three of them are firmly located in the habitable zone. This system is about 40 light-years (235 trillion miles) from Earth. Because of locating outside of our solar system, these planets are scientifically known as exoplanets. This exoplanet system is called TRAPPIST-1, name of telescope in Chile. Researchers using TRAPPIST announced they had discovered three planets in the system and then discovered more to seven by several ground-based telescopes. Moreover, NASA used data from Spitzer to measure the sizes of the seven planets and estimates the masses and density of six of them. The data indicated that they are likely to be rocky and could have liquid water on their surfaces but the mass of the seventh has not been estimated yet. Scientists assumed it could be an icy like snowball world. The temperature of TRAPPIST-1 star is cooler than our sun,…show more content…
We were interested because it has three planets that human can live. Three planets of TRAPPIST-1 system could have life. It could have a life because TRAPPIST-1 system has key of life. Key of life are liquid water and good temperature for life. It can be possible in future that human travel to TRAPPIST-1 system. TRAPPIST-1 system is close to us. Distance between TRAPPIST-1 system and us solar system about 40 light-years or 235 trillion miles. Technology of human develop very fast so in future human will make spaceship that can travel to TRAPPIST-1 system. This news was interesting and was surprising. It is important because if TRAPPIST-1 system has water that is key of life, it can have a life except human and animal in Earth. So earth will not a single planet that have a life in this
