Imagine a planet so close to its star that it completes a full orbit in less than a day. Meet KOI-1843.03, a terrestrial exoplanet that has captured the curiosity of astronomers since its discovery in 2013.
KOI-1843.03 is not just any exoplanet; it’s a terrestrial giant with a mass eight times that of Earth. This hefty planet spins around an M-type star so closely that its orbital period is merely 0.2 days. That’s less than five hours!
The planet’s proximity to its star is as mind-boggling as it is fascinating. Separated by only 0.005 astronomical units, KOI-1843.03 sets a record for its tight orbit. Such closeness challenges our understanding of planet-star interactions and planetary formation theories.
Despite its Earth-like rocky composition, living conditions on KOI-1843.03 would be far from hospitable. The heat from its star and the gravitational forces at play make it an unlikely candidate for life as we know it.
