The masses and physical characteristics of planets are usually predictable based on the distance between them and their star.
Recent space discoveries reported at the TESS Space Conference in MIT announced the unusual observation of an exoplanet, LTT 9779b, which presents itself as a gaseous giant or otherwise known as an “ultra-hot Neptune”, despite its proximity to its sun-like star.
LTT 9779b is 4.6 times the size of Earth and experts believe it might be a matter of time before the atmosphere of the planet is ultimately affected by its nearby star.
This may be the first-time scientists are capturing the elusive transition of a hot gaseous giant into a scorched world through its cooling down process.
