Okay, Skywatcher? What you're missing here is that the newly discovered red dwarf, the star itself, isn't traveling towards us--just the light that comes from it is. The star is 7 light years away, which means that the light that comes from it takes 7 years to get here, but the red dwarf star itself is still staying right where it is, 7 light years away, rotating comfortably, doing its own thing, completely uninterested in suddenly deciding to hurl itself towards a neighboring star and take out the third rock in its planetary system.

Repeat--there is no red dwarf star on a collision course with Earth.


Better now?
