Astronomers have discovered a super-Neptune with one of the lowest densities ever found.

This is the case for TOI-1883 b, a super-Neptune discovered in 2024 by some astronomers.
As a reminder, this telescope is located in Hawaii and it has seven instruments that can observe the universe across different wavelengths.
Therefore, its density is estimated to be only 0.4 g/cm³, which is one of the lowest ever discovered.
Astronomers have discovered a super-Neptune with one of the lowest densities ever found. But while this discovery is important, further studies will need to be conducted to better understand this celestial object.

There are many planets in the universe, each with different compositions and shapes. This is the case for TOI-1883 b, a super-Neptune discovered in 2024 by some astronomers. Located about 383 light-years from Earth, this exoplanet orbits a red dwarf named TOI-1883 every 4.5 days. However, uncertainties remained regarding its mass.
As a result, a team led by Izuru Fukuda of the University of Tokyo in Japan has decided to observe and study this exoplanet using the Infrared Doppler (IRD) instrument on the Subaru Telescope. As a reminder, this telescope is located in Hawaii and it has seven instruments that can observe the universe across different wavelengths.
Thus, the mass of TOI-1883 b is estimated to be about 13.7 times that of Earth, and its radius is about 5.7 times larger than that of our planet. Therefore, its density is estimated to be only 0.4 g/cm³, which is one of the lowest ever discovered.
