Scientists discovered two potentially habitable planets in unusual star system

Scientists estimate they have discovered two ”potentially habitable” exoplanets, belonging to the Star Trappist-1. This star, a faint red dwarf, located 39.6 light-years (12.1 pc) from the Sun, has seven planets, all of them approximately the size of the Earth.

The event has created great interest in the scientific community, as it is the first time that so many planets similar to the Earth have been found around the same star.

The new study, led by Dr. Amy C. Barr Mlinar of the US Planetary Science Institute, to be published in the astronomy and astrophysics magazine, ”Astronomy & Astrophysics”, estimates on the basis of mathematical calculations that, the Trappist-1 d and e planets are the most likely be habitable, due to their mild temperatures and generally their most favorable climatic conditions.

Six of the planets in the system may have the right temperatures for liquid water to exist on their surfaces

D planet is likely to be a water world, covered all by a global ocean, at a temperature of about 15 degrees Celsius.

E planet is cooler, with possible temperatures like Antarctica, while finally, C planet is the most likely to have a solid rocky surface, but too little or no water at all.
