The possibility of the existence of water in the TRAPPIST-1 system is revealed
Nature Astronomy: TRAPPIST-1 system survived minor meteorite bombardments An international team of scientists has calculated how intensely TRAPPIST-1 exoplanets were bombarded in their early stages. This was done with the help of modeling, which showed at what intensity of collisions with celestial bodies a harmonious relationship between the orbital periods of the planets could be maintained. The results of a study revealing the possibility of the existence of water are published in the journal Nature Astronomy. Scientists have created a computer model of the bombardment phase of planetary formation in TRAPPIST-1 to study the effects that its planets could withstand without losing harmony in the form of orbital resonance. So, the time required to complete one revolution around the star is 1.5 days on planet b and 19 days on planet h. Eight “years” on planet b correspond to five years on planet c, three on planet d, two on
