2017年2月22日,美国国家航空航天局宣布发现Trappist-1太阳系,该系统包含7个地球大小的系外行星,它们围绕一颗昏暗的恒星运行。行星的轨道位于“戈尔德洛克区”,使其成为外星生命的主要候选者。 dataset.csv (0)踩踩(0) 所需:1积分 Unity的自动表格导出工具,开发环境Unity2021.3.27f1c2,适用于365Excels_Uni ...
Planetary systems around red dwarf stars are drastically scaled-down compared with the solar system. The innermost of TRAPPIST-1's planets, TRAPPIST-1b, orbits at a distance of 1.07 million miles (1.72 million km), while the outermost planet, TRAPPIST-1h, orbits 5.78 million miles (9.3 millio...

The TRAPPIST-1 system is remarkable for its seven planets that are similar in size, mass, density and stellar heating to the rocky planets Venus, Earth and Mars in the Solar System1. All the TRAPPIST-1 planets have been observed with transmission spectroscopy using the Hubble or Spitzer space...
TRAPPIST-1 is a system of seven Earth-sized worlds orbiting an ultra-cool dwarf star about 120 light-years away. The star, and hence its system of planets, is thought to be between five-to-ten billion years old, up to twice as old as our own solar system. For scientists seeking evide...
Seven rocky planets orbit the nearby dwarf star TRAPPIST-1, providing a unique opportunity to search for atmospheres on small planets outside the Solar System1. Thanks to the recent launch of the James Webb Space Telescope (JWST), possible atmospheric constituents such as carbon dioxide (CO2) ar...
To put TRAPPIST-1's distance into perspective, a spacecraft at the outer edges of the solar system, like the Voyager 1 probe, would still have to travel for over 73,000 years just to get to Proxima b, which is only about 4 light-years from Earth. Therefore, researchers at the ...
A series of four studies have shed new light on the properties of the TRAPPIST-1 planetary system, currently our most optimal hope for evidence of biological life beyond the Solar system.
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. ...
NASA recently discovered a seven-planet solar system called Trappist-1 that is seemingly capable of having water, oxygen, and, yes, life. So your dreams of living out E.T in IRL are not as crazy as you thought. Mind blown. Trappist-1 is a casual 39 light years away from us, so ...
