New Planets That We Could Possibly Live

According to researchers, the Earth is now around 4 billion years old. That is quite a number for an age. The Earth has changed a lot since then; from its structure geographically to its components atmospherically.

The sad news is, instead of helping the planet to preserve its life, the people living on it is hastening its degradation. Also, the earth is not immortal, and it will soon reach its limits. Though it will be hundreds of years more but still, the race of humankind is at stake.

For this reason, researchers from NASA are doing studies beyond the universe to look for any candidate of a new planet where we could live. For years, they have tirelessly navigated the vastness of the cosmos just to look for similar (if not entirely identical) a habitual planet like Earth.

 

Potentially Habitable Planets

Habitable Exoplanets Catalog (HEC) has come up with a list of planets that are considered to be habitable. The following exoplanets are information taken from HEC and the NASA’s Exoplanet Archive.

  1. Proxima Cen b – this is an exoplanet that is around 4.2 light-years away from the Earth. A group of astronomers from different countries has been studying the possibility that life can exist on this planet. Proxima Cen b is around 1.3 of the Earth’s mass. The distance of Proxima Cen b to the star it is orbiting is about 5% of our Sun and Earth’s distance. Because of that, it passed the criteria to be considered as part of Habitable Zone.
  2. Ross 128 b – this exoplanet is around 11 light-years away from the Earth. According to researchers, the size of Ross 128 b is similar to the Earth. It may also have the same surface temperature. This level of warmth technically shows us that it can support life possibly. This exoplanet can complete an orbit to its host star for only 9.9 days. Its host star is Ross 128 and is commonly known to as the red dwarf star.
  3. Kepler-186 f – this exoplanet is the first Earth-size planet found in the habitable zone. It is only about 10% bigger than our world. Others have considered this planet to be the “Earth’s Cousin.” Kepler-186 f is around 490 light-years away from the Earth. This exoplanet is in the area of its system where liquid such as water possibly exist on its surface. Since this planet can be found in the habitable zone and the possibility that water does exist on its surface, it is a place where life can succeed.

There are more exoplanets that astronomers had discovered. The following have been listed too such as TRAPPIST-1e, Gliese 832 c, HD 40307 g, and many more. These exoplanets in the habitable zone suggest that a neighboring planet within the habitable zone should have the conditions that are roughly comparable to those of Earth.

Space Travel

Upon discovering the numerous planets that are considered habitable, what then is the next step that these researchers would do? Because the level they will be making means that it can become the step of the human race. Are we ready to travel through space just to find a new home or should we preserve what we have now?
