A new solar system is revealed before our eyes

1 star is a red dwarf whose mass is 8% of that of our sun and its size is not much larger than that of Jupiter. For this small star are around at least seven planets, which are characterized by Trappist letters 1b to Trappist 1h, in order to the tiny distance of the star, and according to the conventions in force, which wish to follow the name of The star of a letter that is attributed to the planet.
