Since the ball was not moving before it let Aiden's hand, the formula used to calculate the acceleration is , where a is acceleration, v is velocity and t is the time. We put them in the formula and get The acceleration is 490 m/s^2
Of the three stars in the system, the dimmest - called Proxima Centauri - is actually the nearest star to the Sun. The two bright stars, called Alpha Centauri A and B form a close binary system; they are separated by only 23 times the Earth - Sun distance.
