Jul 7, 2025 · TRAPPIST-1 e is a terrestrial exoplanet that orbits a M-type star. Its mass is 0.692 Earths, it takes 6.1 days to complete one orbit of its star, and is 0.02925 AU from its star. Its discovery was announ...
TRAPPIST-1e是围绕超冷矮星TRAPPIST-1运行的7颗岩质行星之一,由Amaury Triaud团队于2016年通过凌日观测法发现。该行星位于距地球约39光年的宝瓶座方向,轨道周期仅为6.1地球日,质量介于地球的0.62-0.77倍之间,半径约为地球的91%,属于地球尺寸的类地行星。作为TRAPPIST-1恒星系内宜居带的主要候选行星,其 ...
Sep 10, 2025 · TRAPPIST-1e是红矮星系统TRAPPIST-1中的第四颗行星,其轨道位于该星系的宜居带内且运行稳定。 这颗行星之所以备受关注,是因为理论上其表面可能存在液态水,但前提是该行星拥有大气层。
Sep 13, 2025 · 如果TRAPPIST-1e确实存在这样的大气层,那么它有可能具备液态水存在的条件,从而成为潜在的宜居行星。 TRAPPIST-1e位于其恒星的宜居带内,这意味着表面温度可能适宜液态水的存在。 此外,即使二氧化碳含量不高,少量的温室效应也可能使行星表面温暖。
Sep 10, 2025 · TRAPPIST-1 是表面溫度極低的超冷紅矮星,距離地球約 39.13 光年,周圍已確認 7 顆類地行星,是已知僅次於太陽和克卜勒 90 的多行星系統。 其中,TRAPPIST-1e 是距離母星第 4 近行星,與 TRAPPIST-1f、TRAPPIST-1g 位於系統適居帶內,溫度不會太高也不會太冷,表面可能存在液態水,前提是行星有大氣保護。
Sep 12, 2025 · Scientists regard exoplanet TRAPPIST-1e as one of the most – if not the most – likely of the seven TRAPPIST-1 planets to have an atmosphere and be potentially habitable.
Sep 9, 2025 · TRAPPIST-1e ticks those boxes in ways few exoplanets can claim, making it a true star of astrobiology. That’s why astronomers are investing precious JWST time into studying it. If TRAPPIST-1e has an atmo...
TRAPPIST-1e,也称为 2MASS J23062928-0502285 e,是一颗接近地球大小的类地系外行星,在 超低温矮星 TRAPPIST-1 周围的 适居带 内运行,距离地球大约40光年(12秒差距,3800000万亿公里,240000000百万英里),位于宝瓶座。这颗系外行星是通过 凌日法 发现的,其中测量了行星穿过其恒星前方时产生的变暗效应 ...
Feb 4, 2025 · An analysis of TRAPPIST-1b, the innermost planet, revealed its dayside temperature and found little evidence of an atmosphere. In a press release on February 22, 2017, NASA announced the discovery of the...
