The detection adds to the small number of rocky planets where atmospheric conditions can be studied from Earth.
The planet was observed using ground-based telescopes that measured changes in starlight as the planet passed in front of its host star. Data indicated the presence of gases surrounding the planet, consistent with an atmosphere. Further measurements showed variations in light that researchers said could not be explained by the planet's surface alone.
The findings were published in a peer-reviewed journal.
The discovery provides a new target for instruments designed to analyze the chemical makeup of exoplanet atmospheres. Researchers said additional observations will be needed to determine the composition of any gases present. No direct evidence of liquid water or biological activity was reported. The planet remains one of several rocky worlds under examination for atmospheric properties.
