On this giant Earth, a year lasts only 12 hours

On this giant Earth, a year lasts only 12 hours

The researchers participated in scanning the sky 15 new exoplanets is found. One of them is TOI-1798 cOne Super Earth. This does not mean that it resembles the Earth, but rather indicates its size. It is super-Earth 30 to 70 greater from Earth.

The newly discovered rocky planet flies so close to its host star that it only stays there for a year 12 hours It lasts. Astronomers refer to this as University of the South Pacific (Over a very short period). “Due to their proximity to the parent star, USPs are extremely hot – it's more than that 3000 times the radiation He explains: “Exposed to what the Earth hits from the sun.” Ian Crosfieldco-author of the related studyin the current situation. This means that TOI-1798 c no longer has an atmosphere.

They are found using the transport method

TOI-1798 c and the other 14 planets were found using a NASA telescope he-goat (Transiting the Exoplanet Survey Satellite). It is used “Transit method“To find exoplanets. The stars become small and regular Light fluctuations investigated and caused by planets orbiting them.

With the WM Keck Observatory On Mauna Kea, Hawaii, astronomers were then able to take a closer look and get details about this planet Dimensions And It rotates in orbit He specifies. From this they were able to draw conclusions about what is possible density And texture. In total, they analyzed 126 exoplanets, including 15 newly discovered ones.

TOI-1824 b

Discovery of an unusual branch of Neptune

Among them is the quasi-Neptune TOI-1824 b. It is though 19 times As big as our Earth, but it has just that 2.6 times Block them. These planets are typically between 6 and 12 times the mass of Earth.

Searching for exoplanets helps learn more about other planetary systems and our own. the Number of currently confirmed exoplanets in our Milky Way Galaxy It is 5,632. There are also 4,193 known planetary systems.

All 126 exoplanets have been examined

According to researchers, our solar system shines compared to other systems abnormal. Many systems have more than one star, while we only have one sun to have. Super-Earths are also common in planetary systems, but none are found in the Solar System. “This indicates that our solar system Less typical “It may be larger than previously thought,” Crosfield says. The study was published in the Astrophysical Journal
