Astronomers discover new worlds for the first time At least three of them may have been habitable as of 2016. Now, a new study suggests the way the TRAPPIST-1 planets orbit may reveal clues about their evolution and how often space rocks crash into them. year of construction
TRAPPIST-1 is located about 40 light-years from the Sun in the constellation Aquarius. TRAPPIST-1 is a dim, cold star known as a red dwarf. which is the most common type in our galaxy. that is the Milky Way Around the star, seven exoplanets the size of Earth. Called by simple letters from TRAPPIST-1 b to h according to the distance from the star.
It orbits in a manner that astronomers refer to as 'resonant'. Resonance means that although each planet takes a different time to orbit one, the planets will not be able to do so. But the pair will meet again at the same starting point.For example, for every 8 orbits completed by planet
TRAPPIST-1 b closest to its star, planet c has 5 cycles, planet d 4 and planet e 2 orbit. Scientists argue that this strange normal orbit is impossible. If those planets were hit too hard by space rock after being born in the protoplanetary disk surrounding the newly formed TRAPPIST-1 star about 7 billion years ago.
