US, WASHINGTON (ORDO NEWS) — In our galactic “region” is a very interesting system TRAPPIST-1, which is only 40 light-years distant from us. This system has seven rocky planets, of which three objects are located in the habitable zone.
To find out whether life can exist on one of the planets, scientists began to look for characteristics that are able to tell the history of the system and individual planets. Recently it was found out that in its structure the system strongly resembles the Solar system. Objects resemble vinyl plastic: they rotate around the star along well-defined paths.
The rotation occurs around the equator of a celestial body.
Since the bodies rotate around the equator of the star, this gives the right to assume that the planets did not change the angle of movement. This greatly facilitates attempts to study the initial state of the system.
When star formation begins, a flat disk of dust and gas appears around the star. It was from space debris that the planets were formed, which subsequently remain ordered, and not randomly moving.
In the TRAPPIST-1 system, the planets are very close to the star, which indicates internal migration, and not the influence of any force or object from the outside. Peaceful surroundings can help create habitable zones. So far, this is only the guesswork of scientists who require confirmation.
Observations with the latest infrared spectrographs will open people a window into the orbital architectures of stellar systems with small masses, experts are sure.
