Superearth found near us
This article talks about how a super-earth( exoplanet) was found nearby and estimated to contain 75% of water. The super-earth is about 10 times the size of earth and is 40 light years away. This planet was found because of a project of finding exoplanets that are close to the characteristics of earth. If it is close to the characteristics it is called the goldilocks zone. I think this is not useful because even though we could live there we could not go there in a instant because it is 40 light years. It would take 40 years even though if we travel light speed. So far they have found 413 exoplanets that are in the goldilocks zone. Most of the planets are very hot and are 200 times hotter than our planet. Also this exoplanet has a atmosphere that is similar to our atmosphere. In addition it is the first planet that is close enough to study its atmosphere. This planet may contain plants and organisms because it has the right temperature and contains 75% of water.
