The star Vega, in the direction of which our solar system is moving at a speed of 20 km / s, is located at a distance of 25 * 10 ^ 13 km from us. How many years later would we be near this star, if it itself did not move in world space?
To determine the time, we assume that Vega moves uniformly and use the formula: t = s / υ When calculating, we obtain the time in seconds and years: t = / υ = 25 · 10 13km / 20km / s = 125 · 10 ^ 11s = 396372 years.
