Exoplanet or exoplanet research has allowed us to discover very different planetary systems. These include gas giants like Jupiter that are very close to their star, gaseous planets like Neptune, or planets that are rocky like Earth. Now, astronomers are making the discovery of an unexpected Neptune-sized planet that is “denser than steel.”In the official press release, it is stated that the discovery of such a large planet the size of Neptune is quite unusual. The study’s authors suggest that the composition of the newly found planet may be the result of a catastrophic collision between two celestial planets. In fact, we are not strangers to such collisions. Because it is believed that the Moon, which is the closest celestial body to us, was formed by another planet colliding with the Earth.

Discovered TOI-1853b is a planet orbiting the orange dwarf star TOI-1853. This exoplanet system was detected by NASA’s Transiting Exoplanet Survey Satellite (TESS) and is located about 544 light-years from Earth in the direction of the Boötes constellation. TOI-1853b consists of a larger proportion of rock mass than would be expected for a Neptune-sized planet. The planet’s mass is twice that of other known similar-sized planets, suggesting that its density is significantly higher.On the other hand, exactly how the planet formed is still unknown. But the researchers were able to create a computer model showing that the planet was formed as a result of a catastrophic planetary collision. This mighty cosmic collision may have destroyed the atmosphere and water that existed before the collision, leaving huge chunks of rock behind. The team speculates that this planet was originally a water-rich world.
Jingyao Dou, co-author of the study, said, “This planet is so amazing! Normally we would expect planets with this much rock to turn into gas giants with a density similar to water like Jupiter. TOI-1853b is the size of Neptune but has a higher density than steel.” uses expressions.
