It seems like you're asking about the altitude of Sputnik 1, the first artificial satellite to orbit Earth.

Sputnik 1 orbited at an average altitude of 215 kilometers (134 miles) above Earth's surface.

It's important to note that the satellite's orbit wasn't perfectly circular. Its altitude varied slightly, with a perigee (closest point to Earth) of 228 km (142 mi) and an apogee (farthest point from Earth) of 257 km (160 mi).

Let me know if you have more questions about Sputnik 1 or other satellites!
