It’s true that X-rays and tidal locking would be a huge problem for life on a rocky planet but aquatic life might survive with water to provide some protection from the radiation and also to serve to spread the heat around.
For what it’s worth, 120 miles is 20.4 light years.
Assuming current technolgy, a massive effort to build a nuclear-pulse engine and space craft(probably could be done in 10-15 years time, if we REALLY got after it) -— say by a benevolent dictator of USA that was really into space.
I bet a voyage would take 30 years one-way, our relativistic time, (5 years to accellerate, 5 to decellerate, 20 years or so at 3/4 speed of light).
Let’s go visit and find out.
