And even if it could, planetary scientists at the University of Washington who have modeled the TRAPPIST-1 system think TRAPPIST-1d would be more likely to have a runaway greenhouse effect like Venus than be habitable like Earth. TRAPPIST-1e The TRAPPIST-1 planets get so close to one ...
The exoplanet TRAPPIST-1e yielded another interesting finding: It is the most similar to Earth in the amount of radiation it receives from its parent star, its size and its density. And liquid water could exist on its surface.在外星球TRAPPIST1-e上得到了另一个有趣的发现:它和地球受到相似的...
The seven Earth-size planets around the distant star TRAPPIST-1 are "tugging" on each other as they travel around their parent star.By carefully observing those tugs, scientists were able to gather information about the planets' composition, and found that some of the TRAPPIST-1 worlds could ...
Just as on Earth, the daytime view from the surface of TRAPPIST-1e will be dominated by its “sun”. But because of the very different properties of TRAPPIST-1 compared to the Sun, the system’s host star would also appear very different. For starters, TRAPPIST-1 would appear as a dis...
TRAPPIST-1 b is the closest planet to the M-dwarf star of the system, and it receives four times as much radiation as Earth receives from the Sun. This relatively large amount of stellar heating suggests that its thermal emission may be measurable. Here we present photometric secondary ...
This range of CMF implies lower Fe/Mg and Fe/Si values compared to Earth (and the Sun). Elemental abundances of rocky interiors are expected to be reflected in the photospheric abundance of the host star as argued by \citet{Unterborn2018a} and \citet{Dorn2018}. Unfortunately, measuring ...

The innermost planet in the system, TRAPPIST-1 b, was found to have a brightness temperature of 503−27+26K (ref. 4). Compared with previous detections of thermal emission from small (Rp<2R⊕) rocky planets (see Extended Data Fig. 1), these temperatures are more than 500 K ...
This system, located 39.5 light years away from earth, is also interesting for its tiny size- the outer worlds orbit far closer their star than Mercury does Sol. While this tiny form factor is hard to duplicate in game, my in-game system is remarkably small compared to other systems I ha...
