39 light-years from Earth, a tiny red dwarf star, TRAPPIST-1, sends its dim light to not one, but seven Earth-sized worlds. All seven exoplanets in the TRAPPIST system are jammed into a space smaller than the distance between Mercury and our Sun. At least three of these rocks are in the habitable zone, meaning... we could live there someday. So we're sending our brave explorer Chase to the TRAPPIST system, to rate all seven planets from the most habitable to the most deadly. 00:00 What If You Traveled to the TRAPPIST System? 02:20 TRAPPIST-1b 09:03 TRAPPIST-1 c 12:42 TRAPPIST-1 d 16:05 TRAPPIST-1 e 19:56 TRAPPIST-1 f 23:12 TRAPPIST-1 g 28:16 TRAPPIST-1 h Support us on Patreon: https://www.patreon.com/whatifshow/membership Get the What if book: http://bit.ly/ytc-the-what-if-100-book Join this channel to get access to perks: https://www.youtube.com/channel/UCphTF9wHwhCt-BzIq-s4V-g/join Interested in sponsoring our episodes or collaborating?
