To answer the question and give some neat info; You would need to travel 41,343,000,000,000km or 4.37ly to reach the closest star to Earth "Alpha Centauri A"

For perspective the distance from the Earth to the Sun is a measly 149,600,000km or 0.00001581273ly, so that's quite a few digits less.

Thanks for the translation of this work. I'm not exactly sure what the author wanted to convey or if it is auto-biographical (why is the brother sick?), but it is a nice slice of life story.
