86 km in diameter we can see from earth

look at the photo of earth they took from the moon

do u think in that photo it is possible to see something on earth 86 km in diameter

what do u think

Hm, I'd want angular diameter calculations given that size and distance, and compare it to pixel measurements of the crater on a picture to get angular diameter of that.

I'll try angular diameter of the crater

u dont need some crazy math for this

the diameter of the crater is 86 km lol

But we kinda do in order to solidify the argument?

ok the diameter of the crater is 86 diameters why do u need more info than that

we can see it from earth

u cant see an 86 km thing the other direction

I need distance as well

Not exact, but that is 238k miles?

384,400 km

It comes to 0.013 degrees

Angular resolution for the eye is generally about 0.02 degrees

Can you see it with the naked eye?

@jeremy you dont' see it with unaided eye, you need binoculars

or somethign

u can see tycho with the naked eye

Hmmm

Tycho is one of the few lunar craters you can actually see with the naked eye. If you stare squarely at it, you'll see a tiny, unresolved bright spot about a quarter of the way in from the southern limb.

I'll have to check that for myself

yeah go look at the moon u can see it unaided

no telescope no zoom can no binoculars

what? no, you can't

lol u can

you can see only the big craters

tycho

u can

def can't see that one without binoculars

you're 100% wrong

lol really google it

might see a dark patch or a change in color

but you can't see tycho with the unaided eye

i have seen it with the naked eye personally but this is common knowledge

no, you haven't

google it
