How many times did Sputnik 2 orbit around the earth?

Sputnik 2 completed approximately 2,570 orbits around the Earth during its time in space. It was launched on November 3, 1957, and remained in orbit until April 14, 1958, when it re-entered the Earth's atmosphere. This mission was significant not only for being the second artificial satellite but also for carrying the first living creature, a dog named Laika.
