Within about 7%

2019-10-15 03:07:38 UTC  

I think that's because the moons orbit is elliptical right?

2019-10-15 03:07:42 UTC  

Yep

2019-10-15 03:07:49 UTC  

sometimes it's farther and sometimes it's closer

2019-10-15 03:07:53 UTC  

And inclined

2019-10-15 03:07:55 UTC  

So we agree the sun and moon have the same apparent size

2019-10-15 03:07:56 UTC  

not by a lot

2019-10-15 03:07:59 UTC  

?

2019-10-15 03:07:59 UTC  

So take the cosine of that

2019-10-15 03:08:17 UTC  

@jeremy they're close but not quite the same

2019-10-15 03:08:18 UTC  

on average, the sun and moon have the same size, no?

2019-10-15 03:08:22 UTC  

Ok stop

2019-10-15 03:08:35 UTC  

Again about 7% . If you call that the same ok, but I don't

2019-10-15 03:08:45 UTC  

We are gonna take our measurement of the sun and moon during a solar eclipse

2019-10-15 03:09:07 UTC  

Right they almost perfectly match at that point in time ?

2019-10-15 03:09:21 UTC  

is the moon slightly bigger in apparent size?

2019-10-15 03:09:48 UTC  

You can't have a total solar eclipse unless the moon's apparent size is equal or greater than the sun, right?

2019-10-15 03:09:52 UTC  

They are extremely close can we go with that ?

2019-10-15 03:10:01 UTC  

Yes

2019-10-15 03:10:06 UTC  

Within 7%

2019-10-15 03:10:20 UTC  

is that 7% area or 7% diameter?

2019-10-15 03:10:21 UTC  

Ok so we need to go back to where u said the angle change was too small for the sun

2019-10-15 03:10:28 UTC  

Well could be up to 14% diff really

2019-10-15 03:10:42 UTC  

@SunRazor ha I dunno, I think it's diameter?

2019-10-15 03:10:56 UTC  
2019-10-15 03:11:15 UTC  

They are the same size almost

2019-10-15 03:11:21 UTC  

Right

2019-10-15 03:11:32 UTC  

How’s the angle change too small for the sun to take the measurement we do for the moon

2019-10-15 03:11:36 UTC  

for all practical purposes, they are the same apparent size

2019-10-15 03:11:51 UTC  

Be cause it's further away

2019-10-15 03:11:56 UTC  

Lol

2019-10-15 03:12:12 UTC  

We r getting the distance with the angle change I thought

2019-10-15 03:12:13 UTC  

The angle change is too small to measure

2019-10-15 03:12:27 UTC  

The angle change is giving us the distance

2019-10-15 03:12:34 UTC  

Ya and with a large enough distance this method is too inaccurate

2019-10-15 03:12:39 UTC  

It’s the same as the moon

2019-10-15 03:13:08 UTC  

Ya but the angle change we get when we do this on the moon is a number much large than the uncertainty in our instrument

2019-10-15 03:13:14 UTC  

If u did the measurement to the moon with ur angles and the sun u get the same number

2019-10-15 03:13:22 UTC  

No they're different

2019-10-15 03:13:30 UTC  

Indicating the moon is much closer

2019-10-15 03:14:04 UTC  

Ok let’s take this nice and slow
