How many BTC are left?

I'm curious to know, can you provide an estimation of how many Bitcoin (BTC) remain unmined or still in circulation? As the total supply of BTC is finite, it's intriguing to ponder the remaining quantity and what implications this might have on the market's future value and accessibility. Additionally, is there any information available on the projected timeline for when the last BTC will be mined, assuming the current mining rate remains consistent?
