SCI/TECH: Runaway Star Travelling Inbound Towards Milky Way.

can anyone figure out how much longer the stars lifespan will b in earth years. i think its called time dilation , something like the faster an object moves through space time the slower its internal clock ticks. im bored does this even make sense. cool find though! and were worried about stopping comets and asteroids from hittin the earth someday, no way u could stop this.
