There are a lot of Bitcoin explorers, but a Bitcoin explorer will usually show the last blocks, the details of a transaction and the details/translations of an address.
What you are asking for are statistics most explorers don't show.

The Circulating Supply is shown by coinmarketcap.
I'll look a bit, maybe I find some of the other data too, but I don't promise results.

Edit: I think that the number of nodes is next to impossible to find out, since one node sees only its peers and I think that no other reporting/cross check is done, possibly even for privacy.

According to https://bitnodes.earn.com/ there are around 10.000 'reachable' nodes. 9464 to be precise. 
Most of them from The United States - 2440, followed by  Germany - 1937 and France - 631
https://bitnodes.earn.com/nodes/live-map/

Not sure how precise that data is though.

I didn't knew coinmarketcap had a blockchain explorer. This website is really growing. I liked the explorer, better than blockchain.com that doesn't show native segwit addresses until now.

The current amount of mined Bitcoin - total circulation supply.
According to coinmarketcap, 17,990,650 already mined (this website considers all of them in circulation. There is no way to know exactly circulation number)

Bitcoin circulating supply   17 990 858.54497237BTC .  ( 599 270 blocks )

exactly circulation = all_block_rewards - ( estimated_all_block_fee_rewards  - real_all_block_fee_rewards )

Of course not. Are Lost bitcoins circulating? Those who the owner died, or lost in HDs, pendrives etc. And no one can determine how much is this number

Theoretically, these bitcoins exist and can be used after achieving quantum superiority, except unspendable scripts  Smiley  But yes you are right determine  circulating impossible if we are talking about the actual value.

Quantum superiority? Man, where do these people learn that names ? Lol.

This makes no sense for so many reasons...
Don't you think cryptography will evaluate together with hardware? Or that if aome privatekeys are breakable, all of them will be as well?

 if that "quantum superiority" ever happens, all bitcoins will be lost. And how will you determine which are lost and which are just  from people that are holding?

I absolutely love that site. It provides so many useful metrics to browse through, that it will keep you entertained for hours non-stop.

You read a few too many of these quantum hype articles. It actually surprised me how hard it picked up in the more recent weeks. I really thought that people would just shake it off and move on but it has gotten in people's head, exactly what news outlets and those sponsoring them want.  Roll Eyes

I'd like to emphasize that it only applies for UTXO where it's public key is known.

You are overthinking it. The network (or code) doesn't go by death certificates. If it's mined it's considered in circulation. And this is what OP was asking for.

1 million allegedly mined by Satoshi
3 to 4 million lost over the years.

About 5 million not moving. I'm sure there's a site out there that can just look a coins that have not moved in over 7 or 8 years, and you have a good idea of coins that are lost, gone, forgotten, or otherwise inaccessible.

Not exactly this but I like to see the list of the richiest bitcoin wallets of all time.
Other than exchanges and big unknown wallets, there is a lot of old wallets with hundreds or thousands of coins lost in there or maybe just waiting for a big pump! https://bitinfocharts.com/top-100-richest-bitcoin-addresses.html

The top 21 has 31k btc and the last movement was in 2010
And others never sent anything. Top 54 to 69 has 12k btc each and never saw movements.

there has been some attempts but all of them are a failure before they even began because bitcoin is pseudonymous and you will never ever be able to look at the blockchain and claim coins are lost just because they have not moved.
for instance i have coins that i received in 2014 and have not moved them ever since (5 years) that doesn't make them lost, i still own the private keys. but in the eyes of many who just look at the blockchain it is categorized under "lost coins"!

We never know, but it's also possible that the owner is no longer alive. Or, just like you said, the owner might sit around and wait for years until 1 Bitcoin equal to whatever price they think it's good enough to sell.

for instance i have coins that i received in 2014 and have not moved them ever since (5 years) that doesn't make them lost, i still own the private keys. but in the eyes of many who just look at the blockchain it is categorized under "lost coins"!

I also believe that 'lost coins' categories should only apply to coins whose private key is lost (regardless of what the reason is). We should use 'cold coins' or something similar to refer an address or coins that stuck in an address for a long time. Technically, we don't know which address no longer has accessible private key anyway.

Maybe 5 years is too short to consider, I did say look at older unmoved coins. In the real world, outside, banks consider accounts inactive as short as 1 year but as long as 10 years.

I think it's good practice, even in bitcoin, to move your old coins to new addresses every few years. A chance to consolidate inputs for lower future fees, as well as to upgrade to new address formats or new wallets.

well i haven't been around for that long to have such old coins but i expect to be around for another decade and then these coins would be 15 years old and i will not have moved them still. there is no reason to move them, it is mainly the first coins i have ever bought and there isn't that many inputs for me to consolidate so there is no problem with the fees. i am also holding it for sentimental values.
