Weather On Lava Planets
Earth has managed to contain all the conditions which are suitable for life, a trait that makes it special among the other planets in our solar system. While some have imagined the frigid conditions on Mars or the toxic atmosphere of Venus, there are planes that are far more extreme.
A team of researchers has managed to gather interesting information about lava planets, who are so close to their star that intense temperatures lead to the appearance of molten oceans and remarkable weather events.
The team of researchers employed sophisticated software simulations to anticipate the environmental conditions that might be encountered on K2-141b, an exoplanet that is as large as Earth and is dominated by the presence of rocks in its sky, on the surface, and in the oceans.
With the data offered by the simulation, the researchers painted a grim portrait of the planet. If during the night the temperatures can drop below 200 degrees Celsius, they can rise up 3000 degrees Celsius during the day, leading to zones with a very thin atmosphere that is also surrounded by a magma ocean.
Interesting rock circuit
With such high temperatures, some of the rocks become vapor that is carried around the planet by supersonic wind. At certain heights, the mineral will start to condense and return to the oceans of magma due to the cold temperatures that can be experienced during the night. A permanent circuit is established.
It is worth noting that all the rocky planets start as a lava planet, but most manage to cool down and solidify at some point. Since K2-141b is so close to its home star, it is unable to cool down, and it is likely that it will remain a lava planet for as long as the start will be active.
