According to the study done by a team of scientists and in the tireless search to find another alien earth in the universe, they’ve found an interesting place to investigate. That’s the Super-Earth K2-18b. This exoplanet has been described as a large rocky planet being suitable to support life.
How and when the Super-Earth K2-18b was discovered?
In early January 2015, NASA announced about this planet K2-18b, along with the other two known planets in the K2-3 system. It was announced as a part of the first results from the second mission of the Kepler spacecraft. This spacecraft was launched from Kepler space observatory of NASA in order to discover Earth-size planets orbiting other stars.
How the research was carried on The Super-Earth K2-18b?
Using data from the European Southern Observatory’s (ESO’s) High Accuracy Radial Velocity Planet Searcher (HARPS), researchers were able to learn more about K2-18b. The team carefully observed radial velocity data about K2-18b’s star i.e. the K2-18, in order to determine the planet’s mass.
What actually is the Super-Earth K2-18b?
In short, K2-18b also known as EPIC 201912552 b is an exoplanet(a planet which orbits a star outside the solar system) orbiting the red dwarf star K2-18 every 33 days. It is 111 light years(1,050,141,082,456,468.8 Kilometers) away in the constellation Leo.
What’s exciting about the Super-Earth K2-18b?
This planet was found to be orbiting within the star’s habitable zone, which happens to be a red dwarf. Thus, making it an ideal exoplanet to have liquid surface water and potentially, life. The presence of water is yet under controversy.
What’s so controversial about the Super-Earth K2-18b?
The planet may have a rocky surface and an atmosphere similar to that of Earth’s. However, it is also not to be sure that it could be primarily water-based with a thick ice surface with same assumptions of having oceans of liquid water on its surface.
