Math in a blog? it's a TRAPPIST-1

39 Light Years?! We’re Going to Need a Bigger Rocket…

  • NASA’s recent discovery of the solar system TRAPPIST-1 sparks wonder, curiosity, and many questions! Here is what we know:

    • Within this system there are seven relatively earth sized planets
    • Three of theses planets are in the habitable zone and all of them could have liquid water
    • The TRAPPIST-1 system is different from our own, with the planets very close together, and a smaller sun
    • These new worlds pose the possibility of discovering new life, and maybe even the future of multi-planetary human habitation

    So it seems like the perfect adventure, but at 39 light years away, how long would it take us to get there?

39 light years is only a difficult number to quantify due to its units. It’s a long way, but how long would it take to get there with our best spacecraft? Would we be able to see new life forms within a human lifetime? Science Galaxy’s team got curious, and decided to do some math!

Math of how long it would take

1,055,091.38 years is a long time, and obviously much longer than would be practical for the human race. So while it is exciting to discover TRAPPIST-1, we are left with many questions until the rockets of the future can bring us there, such as:

    • How fast (mph) would a spacecraft need to be going to reach the TRAPPIST-1 system within 10 years? Or maybe 1 year?
    • How many pounds of dehydrated space food would you have to store in the ship to sustain you for a year?
    • What rocket technology is currently in the works? Is the TRAPPIST-1 system truly out of reach?
    • Could a wormhole help us get there?

    In the meantime we will continue to dream, and imagine what it will be like when we get there.

    For more information on the TRAPPIST-1 system visit the TRAPPIST-1 aggregate website, and the NASA Tumblr.
