Moon Gravitational Lens
Can we measure the Moon's gravitational lens?
The angle of the deviation is directly proportional to the mass of the lens.
Apparently the 1919 test with the sun confirmed a 2 arc second deviation.
I can't find it on the web right now but I think we might be trying a test with Jupiter.
The Sun is 1047 times Jupiter.
We must be able to detect a deviation of 2/1047 arc seconds.
The Sun is roughly 3* 10^4 times the Moon.
Could we reliably detect 2/30,000 arc seconds?
After a few minutes I added this comment:
The obvious problem with such a tiny number is when nothing is detected. That means either the equipment failed at this fine resolution or else the moon (having no electric field) cannot be a gravitational lens.
On 04/06/2019 I added this comment:
Both rough estimates are wrong. The moon's mass is much less but its distance is much shorter. The distance to Jupiter is roughly 4 times that to the Sun. I did not attempt either calculation as this post just asks a general question.
