Are planets in the TRAPPIST-1 system closer to Earth than scientist thought?

The study indicates that all seven planets are mostly made of rock. In addition, up to five percent of their mass is said to be in water – which is a very significant amount, given that just 0.02 percent of the Earth’s mass is tied up in its oceans.

I thought the video went with the link. It is still a great video.

Pretty cool.
Imagine being on a planet where you can clearly see neighboring planets.
I liked the Exploring Our Solar System video.
There were some great images of the planets.
I liked how they compared all of the planets to one another and to Earth.
