Prior to 1957, the only artificial satellite orbiting the Earth was the United States' Vanguard 1, which was launched on March 17, 1958. However, before that, the first successful artificial satellite was the Soviet Union's Sputnik 1, launched on October 4, 1957. Therefore, before Sputnik 1's launch, there were no artificial satellites in orbit.
