What would our night sky look like if the solar system was 100 light years from the centre of the Milky Way
I have tried to collate some info from various other answers.
Density of stars where we are:
About 0.15 per cubic parsec
Density of stars &quot;at the middle of the galaxy&quot;.  Unfortunately I don't know how &quot;100 ly&quot; affects this. It's probably about this figure.
About 50-100 stars per cubic parsec
So in this QA it's &quot;about 500x as dense&quot;.
It would seem that this is in fact:
Not very bright. About the same amount of light overall as when there's a full moon.
However the overwhelming factor is
If one particular star was &quot;very close&quot; to us?
How likely would it be, in the region under discussion, that another star is &quot;very&quot; close to us - close enough that that one particular star is extremely bright?
The answer seems to be
No, the stars there are not so close that you'd typically be close enough to a really bright star that it would be bright.
That seems to be the bottom line.
(There's a completely pointless, if pretty, image here showing what it's like &quot;inside a star cluster&quot; {where? At what depth?} here  Unfortunately that image does not simply state the star density they are simulating - so it is of no help at all to this excellent QA!)
the bottom line then:
&quot;If our solar system was only 100 light years from the centre of the Galaxy, would we still have a dark night sky?&quot;  Answer, yes, there would just be &quot;more stars&quot;. It would be hardly any brighter.
To improve on this answer, the next thing we need to quantify is one piece of information:
What actually is the star density at &quot;100 ly from the center&quot;?
Is it 50, 100, 25, 300, 72.275 stars per cubic parsec?
I don't know.


A fun point, would it be different (slightly? a lot?) if inside the galactic bar?  IDK.
