Can someone confirm this astronomical calculation re: distance of nearest black hole?

In trying to explain to my nephew how far we are from the nearest black hole this is what I came up with:
If you hold four sheets of paper together with an outer sheet being blue representing earth and the other outer sheet being yellow representing the sun, and the distance between the blue and yellow sheet represent the distance between the earth and sun then the nearest black hole is 20 miles away from the blue sheet.
I think that's a fairly close calculation, but how far off am I?

I’m sorry, I was told there would be no math.

Sounds about right. The nearest black hole I would assume is the center of our own galaxy and we are sort of kind of on the outer edge, so the distance to our sun is nothing in comparison.

You realize you’re on tigerdroppings innit

You’re high and your nephew is a chair with a jacket hanging over it.

If you are saying that the width of two sheets of paper is analogous to one astronomical unit and the multiple of that width equals twenty miles, which itself would be analogous to the distance from Earth to said black hole, that’s fine.
However, I have not a clue how far it is from Earth to the nearest black hole…

Just googled it. Sure Nuff, it’s three hundred fifty miles.

Are we talking notebook paper or a fine card stock?

That would be Sagittarius A. There are much closer known black holes and probably even closer ones that haven't been detected.

Good to know. Should have said at worst, center of galaxy.

I wouldn't have a piece of paper represent the earth and have the sun three sheets away
But the rest may be accurate

Apparently a black hole is 1600 light years away and the sun is 8 light minutes away.

I just Google mapped nearest black hole.
It is at intersection of Planck Rd. and Hwy Gaia BH1 in Central, La.

Just tell him not to worry about things he can't control.

I got as small as millimeters in my calculation and sheets of paper are usually .1mm thick.
