u think u can still see that line if u were anotehr 200,000 miles away ?

2019-04-22 00:01:08 UTC  

Hm,

2019-04-22 00:01:43 UTC  

Idk, would be hard to make out with the eye

2019-04-22 00:01:49 UTC  

whats ur honest opinion

2019-04-22 00:01:55 UTC  

I don't think so

2019-04-22 00:02:01 UTC  

yeah of course not

2019-04-22 00:02:03 UTC  

No, I doubt it

2019-04-22 00:02:09 UTC  

no way u are seeing that another 200k miles out

2019-04-22 00:02:18 UTC  

So what is your point?

2019-04-22 00:02:36 UTC  

the moon is 238k miles away

2019-04-22 00:02:46 UTC  

about 200k more miles than u were zoomed out just now

2019-04-22 00:02:56 UTC  

198k more miles give or take

2019-04-22 00:03:23 UTC  

u can see a crater on the moon its called tycho with the naked eye its 86 km in diameter

2019-04-22 00:03:59 UTC  

I'll look it up

2019-04-22 00:04:29 UTC  

Oh yeah, that one

2019-04-22 00:04:38 UTC  

The most noticeable

2019-04-22 00:05:19 UTC  

86 km in diameter we can see from earth

2019-04-22 00:05:28 UTC  

look at the photo of earth they took from the moon

2019-04-22 00:05:50 UTC  

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

2019-04-22 00:08:20 UTC  

what do u think

2019-04-22 00:09:52 UTC  

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.

2019-04-22 00:10:05 UTC  

I'll try angular diameter of the crater

2019-04-22 00:10:09 UTC  

u dont need some crazy math for this

2019-04-22 00:10:18 UTC  

the diameter of the crater is 86 km lol

2019-04-22 00:10:37 UTC  

But we kinda do in order to solidify the argument?

2019-04-22 00:11:10 UTC  

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

2019-04-22 00:11:19 UTC  

we can see it from earth

2019-04-22 00:11:40 UTC  

u cant see an 86 km thing the other direction

2019-04-22 00:12:38 UTC  

I need distance as well

2019-04-22 00:13:08 UTC  

Not exact, but that is 238k miles?

2019-04-22 00:14:30 UTC  

384,400 km

2019-04-22 00:16:38 UTC  

It comes to 0.013 degrees

2019-04-22 00:17:48 UTC  

Angular resolution for the eye is generally about 0.02 degrees

2019-04-22 00:18:48 UTC  

Can you see it with the naked eye?

2019-04-22 00:21:53 UTC  

death

2019-04-22 00:21:54 UTC  

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

2019-04-22 00:21:55 UTC  

or somethign

2019-04-22 00:22:20 UTC  

u can see tycho with the naked eye

2019-04-22 00:22:27 UTC  

Hmmm

2019-04-22 00:22:36 UTC  

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.
