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 million km) from the star. Compare those distances to our solar system, where the innermost planet, ...
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.为了感受TRAPPIST-1的距离。举个栗子,...
But the researchers also found that the ice-rich TRAPPIST-1 planets are much closer to their host star than the ice line. The “ice line” in any solar system, including TRAPPIST-1’s, is the distance from the star beyond which water exists as ice and can be accreted into a planet; ...
More importantly, three of the planets are at the perfect distance from the Sun. 29.___If there is liquid water, there would be life.30.___Next, they will try to find out if the planets have atmospheres (大气层).A. It means there could be liquid water (液态水) on them.B. That...
Overview TRAPPIST-1 is a remarkable planetary system, with at least seven planets in a compact configuration orbiting a small star. The farthest detected planet is at a distance of about 6% the Earth-sun distance. This system is...

Three of these planets were found to be in the so-called habitable zone-a distance from the star that means the planets are neither too hot nor too cold to prevent liquid water from pooling on their surfaces. The fact that the planets are very close together has also raised the ...
A key feature of the Trappist-1 system is its monotonic decrease in bulk density with growing distance from the central star, which indicates an ice mass f... A Schneeberger,O Mousis,M Deleuil,... - 《Astronomy & Astrophysics》 被引量: 0发表: 2024年 ...
