The seven Earth-size planets around the distant star TRAPPIST-1 are "tugging" on each other as they travel around their parent star. 这七颗类地行星相互“牵扯”着彼此一起绕着它们遥远的母星TRAPPIST-1运行 By carefully observing those tugs, scientists were able to gather information about the plan...
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 ...
The planets go around a dwarf star (矮星) called Trappist-1. It is much smaller and cooler than our Sun. They are about 40 light-years (光年) from the Earth. 27.___But scientists say it's a little close."28.___If you lived on one of them, you could possibly see the clouds...
A size comparison of the planets of the TRAPPIST-1 system, lined up in order of increasing distance from their host star. (Image credit: NASA/R. Hurt/T. Pyle) TRAPPIST-1b TRAPPIST-1b, the innermost planet in the TRAPPIST-1 system, is a rocky world that's similar in size to Earth....
The latest properties for the planets in the TRAPPIST-1 system based on the work of Delrez et al. and Grimm et al. are summarized below in Table 2. Also included is the amount of energy each exoplanet receives from its host star, or effective stellar flux (Seff), compared to Earth. ...
Thinner atmospheres or bare-rock surfaces are consistent with our measured planet-to-star flux ratio. The absence of a thick, CO2-rich atmosphere on TRAPPIST-1 c suggests a relatively volatile-poor formation history, with less than 9.5−2.3+7.5 Earth oceans of water. If all planets in ...

the timing of the transits as the planets repeatedly circle their star. Looking at all this information together, scientists can figure out the planets’ masses as well as their sizes, something they can’t always do. And that allows them to infer that these are rocky, Earth-si...
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...
