How many dead satellites are in space?

Excuse me, but could you clarify something for me? I'm intrigued by the notion of dead satellites orbiting our planet. It seems like an interesting and somewhat unsettling topic. How many of these defunct spacecraft are currently floating aimlessly in space? Do we have a definitive count, or is it an estimation based on tracking and data analysis? It's fascinating to ponder the potential implications of so many inactive satellites, and I'm eager to learn more about their current state and any potential consequences they may pose.
