What is the name of the first satellite sent into space?

As cool as going into space sounds, it’s a tad bit dangerous. It makes sense that we would first see if we could even manage to get an object into orbit before strapping a living human being into a rocket and shooting them into the sky hoping for the best. Just like the rockets we would use later, every satellite has its own name. Do you know the name of the first satellite to make it into space?
