2e8bae43f2e13e9 - Astronomers have found that a "super hot Jupiter" orbits its star in only 16 hours

astronomers have discovered some “hot Jupiter” in the past few years. These planets are similar to our own gas giant planets; However, they orbit their stars in less than 10 days

the recently discovered one is called “super hot Jupiter”, because the surface of the planet is considered to be more than 3500 Kelvin – close to 6000 degrees Fahrenheit. It’s almost as hot as a small star. Scientists named the planet toi-2109b, which is the second hottest planet we have found so far

but what really makes this gas giant planet so interesting is that it orbits its star in 16 hours. This means that a whole year is shorter than a normal earth day. Scientists believe that the planet may be in its “orbital decay”. In essence, it is slowly circling its star, getting closer and closer, until one day it hits it

NASA’s transit exoplanet survey satellite (TESS) mission found this super hot planet. The findings were published in the journal Astronomy on Tuesday. This paper details this discovery and everything else scientists have discovered so far

Ian Wong, the lead author of the discovery, said that we may know how the planet approaches its star in a year or two. Although it moves so fast to the star, Huang said we won’t see it fall into the star in our lifetime. On the contrary, Wong and his colleagues think it will take another 10 million years, and even then, it may still be some distance from the star

NASA’s Tess satellite began observing toi-2109 in May 2020. It is located in the southern constellation Hercules. It is about 855 light-years away from the earth. It is the 2109th object of interest discovered by Tess satellite. The spacecraft spent a month measuring the light and cross section of the star. Transit is the periodic decline of starlight. Scientists use it to indicate that a planet passes in front of a star. These data confirm that there is a celestial body around the star every 16 hours
