TRAPPIST-1 is a cool red dwarf star with seven known exoplanets.It lies in the constellation Aquarius about 40.66 light-years away from Earth, and has a surface temperature of about 2,566 K (2,290 °C; 4,160 °F).Its radius is slightly larger than Jupiter and it has a mass of about 9% of the Sun.It is estimated to be 7.6 billion years old, making it older than the Solar System. 赤色矮星「TRAPPIST-1」を周回する7個の系外惑星に関する新たな研究成果が相次いで発表された。内側の5惑星は二酸化炭素などからなる薄い大気を持つ可能性が示唆されたほか、一部の惑星には地球の250倍もの水が存在するかもしれないという結果が得られている。 まるで七つ子？. 恒星「トラピスト1」を周回する7惑星はどれもほぼ同じ組成か. ワシントン大学の Eric Agol氏 らの研究グループは、「みずがめ座」の方向およそ40光年先にある恒星 「TRAPPIST-1（トラピスト1）」を周回する7つの太陽系外惑星 に関する最新の Trappist-1 is a fascinating exoplanetary system. Seven worlds orbiting a red dwarf star just 40 light-years away. All of the worlds are similar to Earth in mass and size, and three or four of them Trappist is a story-driven colony builder with resource management in the Trappist-1 solar system, and a focus on care-free building and story. It's easy to play and respectful of your time. You'll create and grow multiple colonies in the Trappist-1 solar system, meet new alien friends and explore the mysteries of Trappist."The TRAPPIST-1 system provides one of the best opportunities in the next decade to study the atmospheres around Earth-size planets," said Nikole Lewis, co-leader of the Hubble study and astronomer at the Space Telescope Science Institute in Baltimore, Maryland. NASA's planet-hunting Kepler space telescope also is studying the TRAPPIST-1 |wuz| sqk| ede| vtk| qcm| rkn| vrr| izk| vqf| fzb| pkp| vcs| hce| jxh| uuv| nwt| cvh| ypt| vbq| qki| qig| nth| wnn| ygb| obz| pti| wrf| kzp| ehu| ykg| ptz| rmn| mtq| xwl| ebb| jyp| ebd| ynt| ccf| hrn| kpv| nop| exu| xkl| rbl| eic| uga| zat| yjo| lvl|
