THE MOVEMENT OF OUR SOLAR SYSTEM
Reading edition
It has been shown that our whole solar system is sweeping through space at the speed of about ten miles a second towards the stars in the constellation Hercules, and particularly towards Vega, one of its suns. However, Vega is likewise moving through space, so that by the time our sun reaches the spot now occupied by Vega (half a million years or so) Vega will no longer occupy that position, and no “collision” will take place in consequence! We shall not, in fact, pass very near that star.
