I am very surprised that such a system is dynamically stable. You'd expect planets that close together to perturb one another quite a bit. I'm looking forward to reading more about this.

And yes, it's a gorgeous, unexpected image, isn't it? I love living in our current age of discovery.

From that article: "In contrast to our sun, the TRAPPIST-1 star – classified as an ultra-cool dwarf – is so cool that liquid water could survive on planets orbiting very close to it, closer than is possible on planets in our solar system. All seven of the TRAPPIST-1 planetary orbits are closer to their host star than Mercury is to our sun. The planets also are very close to each other. If a person was standing on one of the planet’s surface, they could gaze up and potentially see geological features or clouds of neighboring worlds, which would sometimes appear larger than the moon in Earth's sky.

The planets may also be tidally locked to their star, which means the same side of the planet is always facing the star, therefore each side is either perpetual day or night. This could mean they have weather patterns totally unlike those on Earth, such as strong winds blowing from the day side to the night side, and extreme temperature changes."

That is a cool image - standing on one planet and seeing that level of detail on another planet with the naked eye.   Somehow feels like E.R. Burroughs' John Carter of Mars-ish.

Breaks the system generation rules for MT. :)
