GJ 9827 d is the smallest exoplanet identified to date that possesses water vapor in its atmosphere.

Astronomers at the University of Montreal’s Trottier Institute for Research on Exoplanets (IREx) used the Webb Space Telescope to study the atmosphere of the planet.

The discovery of considerable water vapor on the planet is a monumental achievement in exoplanetary studies.

The prospect of this planet being habitable is quite slim.
