A winter freeze will destroy Pluto’s atmosphere by the year 2030.
Scientists have been studying Pluto’s atmosphere and evolution since 1988.
Pluto completes a long orbit around the sun every 248 years.
Its distance from the sun means it gets very cold.
From information gathered from telescopes and the new horizons spacecraft flyby of Pluto in 2015, scientists were able to predict the atmosphere was going to frost-out and vanish by 2030.
If that happens, the study says Pluto may appear brighter because it will reflect more sunlight.
