But of the more than 6,300 exoplanets cataloged thus far, the vast majority are not rocky, and only a handful of the rocky worlds appear to have an atmosphere.
Astronomers have identified the coldest of the known lava planets that have the atmosphere, a talk about the world called HD 3167b. Most likely, according to an original scientific article, the Earth was previously similar to this lava world. More detailed is in Phys. Read further...
Astronomers have discovered the coldest known lava planets that has an atmosphere, and it has surprised scientists.
An extremely hot rock planet, despite its proximity to the star, shows clear indications of an atmosphere. Measurements with the James Webb Space Telescope show that the day side of HD 3167 b is much cooler than expected with a dark, airless rock body. The find limits at which temperatures lava worlds can hold their gas envelopes. Chicago (U.S.A.). Lava worlds are small rock planets, [...] The post Coolest lava world could possess atmosphere and…
