Hello guys, We're here with some new information from NASA : 
History changed on Oct. 4, 1957, when the Soviet Union successfully launched Sputnik from the Baikonur Cosmodrome in Kazakhstan. The world's first artificial satellite was about the size of a beach ball, about 23 inches in diameter and weighing less than 190 pounds.
