It would help to have enough mass to get us through a big solar flare.
A big solar flare while they were out that far would probably kill the lot of them.
These particles can hit the Earth within 15 minutes to 2 hours of the solar flare.
But at the same time, they could hardly stay out here during the solar flare.
Learning how to make solar flares will be the hard part.
The only way to ward yourself from a solar flare is to put a lot of mass between you and, the sun.
Yet the most violent effects of the solar flare are still to come.
In the future, solar flares threaten all life on Earth.
The next morning the skies are on fire from the solar flare.
Much like this one: a solar flare, with no sun beneath it.
