A super-Earth is an extra solar planet with a mass higher than Earth's, but substantially below those of the Solar System's ice giants, Uranus and Neptune, which are 14.5 and 17 times Earth's, respectively.
K2-18b is one o the super-Earth. Super-Earth is the planets that are about the size of Neptune.
The scientist concludes from the observation of Kepler mission that super-earth about124 Lights year away from the earth exits.
K2-18b is in a habitable zone. It means that the Planet has the condition to make water light at a common temperature. Although, scientists discover various other exoplanets.
Various features excite scientists to have a life on K2-18b. Here I mention some magnificent features of this giant Earth with the possibility of life struggles over it.
- K2-18b is about 8times heavier than the Earth.
- The Planet revolves around a Red Rowaf Star that is a small dim star.
- Scientists come to find that life on K2-18b is tough. The Planet has no magnetic field that makes it more exposed to radiations.
- The gravity of K2-18b is 11.57m/s2. It is near the Earth's gravity.
- A year over the K2-18b is about 33days.
- The air composition of K2-18b has a survivable amount of hydrogen, helium and 0.01% water vapors.
- It’s a very tough job to live on the K2-18b. You require more time for breathing because the air is much heavier.
- Water requires more time for boiling. A heavier planet means we need more fuel to run the machines. Rockets consume more fuels and require engineering designs that are suitable for K2-18b conditions.
- The harmful radiations increase the risks of skin ailments and cancers on the K2-18b.
- You require more effort to walk. Your casual walk is like running a marathon.
- The K2-18b has no moon, which means our nights are definite dark.
- The high gravity shakes the core of K2-18b more as compared to Earth. It means more volcanic Eruption and Super-Earth quakes.
Due to exposure to viral radiations, It's impossible to live on the ground surface of K2-18b.
After living on the K2-18b for centuries, the human body will evolve according to the circumstances.
