against’It is a timely discovery! An international team of researchers led by Quebecir Charles Kedio, a doctoral student at the University of Montreal, and his research director, astrophysicist René Doyon, believe they have found an oceanic world in orbit around a red dwarf in a binary star system relatively close to the Sun.
Discovered in the constellation of the Dragon, two years ago, thanks to NASA’s Tess Space Telescope (Transit Satellite for Exoplanet Reconnaissance), this exoplanet called TOI-1452b will already be a hundred light-years away from us.

First, by analyzing data from TESS, who observed this planet passing in front of its star, they were able to find out its size: 70% larger than our planet. Earth type superhero! Then they set out to measure another specific parameter thanks to which scientists were able to get an idea of what the exoplanets looked like: their mass.
