JAKARTA – Since 1995, the United States Aeronautics and Space Administration (NASA) has been actively searching for exoplanets in the Milky Way Galaxy. Even though it was difficult at first, they managed to confirm thousands of exoplanets.
NASA has discovered 10,062 exoplanets, but not all exoplanet candidates have been confirmed. So far, NASA has only confirmed 5,572 exoplanets with five classifications, namely Neptune, Gas Giant, Super Earth, Terrestrial, and unknown.
The Neptune category is a group of exoplanets that are considered similar to Neptune or Uranus. This category dominates with 1,912 exoplanets, while the Gas Giant category follows in second place.
Gas Giants are a group of exoplanets that are rich in gas and similar to Jupiter or Saturn, this category contains 1,775 planets. Meanwhile, the Super Earth category shows that the exoplanet is different from the planets in the Solar System.
In this category, exoplanets are more massive than Earth, but lighter in mass than Neptune. Exoplanets that fall into this category can be made of gas, rock, or a combination of both. This category has 1,679 planets.
Next, NASA grouped 199 exoplanets into the Terrestrial group. In this category, exoplanets are similar to Earth, but have a rocky surface and are rich in iron like the planets Mercury, Venus, Earth and Mars.
The last group is a group that NASA cannot yet explain. They still don’t have any information on the remaining seven planets so these exoplanets fall into the Unknown category.
The last exoplanet that NASA managed to discover was KMT-2019-BLG-0335Lb. This exoplanet is included in the Gas Giant category with a mass 21 times that of Jupiter. KMT-2019-BLG-0335Lb was discovered last year using the gravitational microlensing method.
