Hey there!
When we have plate tectonics on our planet, we are subject to some unique phenomena, like:
A Mid-Ocean Ridge
Seafloor spreading
Earthquakes
Volcanos
Mountain Ranges
If the Moon were to have plates, we’d probably see geographic landforms like these, and it’s safe to say the Moon probably only has craters and elevations is because it’s uneven and probably was created from breaking off the Earth or another object. It would also have to have earthquakes and ground movement, and it doesn’t have this- at least that’s as much as we know.
Hope this helps!
Answer:The angular seperation is 
Explanation:
For two objects separated by a distance 's' and at a distance 'd' from the observer the angular separation ignoring the physical effects is given by
In the given question
light years
We know that in 1 light year there are 
Using the calculated values we get
Since π radians equals 180 degrees thus we have
