Have Scientist found a second Earth? Have they found a truly habitable planet that can host life? Is it possible for scientist to measure a habitable planet’s atmosphere? The answer to these questions is no. Scientists have not found another planet that can be humanly habitable. Scientist may have found habitable planets but they have not found humanly habitable planets. Scientist have not found a humanly habitable exoplanet because, habitable exoplanet just means it is in the habitable zone, not that it is in fact humanly habitable, scientist are not even sure if there is water on the possibly habitable exoplanets, and it is hard with the technology we have to study exoplanets, therefore, scientists know little about exoplanets. To scientists a habitable planet means a planet that is in the habitable zone within the atmosphere. A habitable zone is when a planet is in an orbit…show more content… Water is important because, humans need water to not dehydrate, and plants need water to grow and humans need plants for oxygen. If there is no water that means there are no organism or no life. If a planet has water that means there is a chance that it already has life on it, and if there is not it means that there is a chance that humans could live on it. If a habitable exoplanet was found scientists would then have to find a way to get people to that planet. Kapteyn-b is the closest habitable exoplanet to Earth, but is still 13 light years away (Dvorsky; Wenz). That is 76,422,129,851,386.89 miles from Earth. It takes astronauts 3 days to go to the moon, which is 238,855 miles away from Earth (How Far Away Is the Moon?). Therefore to travel to Kapteyn-b it would take about 2,629,742 years, or 2,630 millenniums. This is not possible because we do not have the supplies or resources to send a spaceship into space for that
