The Trappist One star system was fully discovered in 2017, whereas until then only 2 of the 7 planets were known. The Trappist 1 star is classified as an ultra-cool Red Dwarf, or particularly a type M8V star. In common terms, these stars carry out fusion at a relatively slow rate, therefore they generate a lower amount of energy when compared to O or B type stars.
In particular, Trappist One star is fairly larger than Jupiter, but more massive with approximately 0.089 ± 0.006 solar masses. Due to its small size, the “Goldilocks” or habitable zone for the planets is very close the parent star, which in turn makes them tidally locked.
What does tidally locked mean? How will that affect my experience on one of the planets?
What does tidally locked mean? How will that affect my experience on one of the planets?
In essence, the term “tidally locked” suggests that at any moment, only one side of the planet faces the star, making the other permanently dark. We recommend that you, as a traveler, visit one of our recommended sources on this topic and decide whether this natural phenomenon will fit your lifestyle and preferences. However, concerning the offered interstellar destinations, Trappist 1D and Trappist 1E, there is no substantial temperature change since they possess a thick atmosphere rich in greenhouse gases. For further information regarding specifics for these two planets, visit the sections below this article.

About the neighbors, Trappist 1B and Trappist 1C
Trappist 1B
Trappist 1B
Trappist 1B is easily depicted as a sister to Venus since a great greenhouse effect caused its surface temperatures to raise 500 to 1700 degrees Celsius on the dark side and the one facing its parent star respectively. Similarly to our nearby neighbor, Trappist 1B has a surface pressure 10,000 times that of Earth, creating conditions unsustainable to life as we know it.
Trappist 1C
Trappist 1C
Trappist 1C orbits approximately 1.4 million kilometers away from the Trappist 1 star. Due to its proximity to the parent star, to complete a full orbit Trappist 1C takes about 58 hours. Additionally it receives 2 times the starlight Earth does from the Sun and is 10% more massive. Similarly to Trappist 1B, 1C has a thick water vapor atmosphere, and although it is not as hot, it cannot harbor human life.
