An article published in the journal “Astronomy & Astrophysics” reports a study of the exoplanet TOI-1807 b, a rocky planet discovered in 2020 thanks to NASA’s TESS space telescope. A team of researchers led by the Italian National Institute of Astrophysics and the University of Padua used the HARPS-N spectrograph installed on the Galileo National Telescope in the Canary Islands to conduct follow-up examinations of TOI-1807 b. The conclusion is that it’s a slightly larger exoplanet than Earth but the main peculiarity is that it’s the youngest of the type with an ultra-short period orbit, as it’s estimated to be around 300 million years old and its year lasts about 13 hours.
