To be clear, there are about ~15,000 objects (active + debris) in orbit ranging from small debris chunks to active spacecraft.

Starlink alone is expected to add ~30,000 active satellites with relatively large solar panels/bodies, which by virtue of their area alone can be expected to be more visible from the Earth than most of the small objects that are currently tracked.

Ok, sure, so here's a valid argument from you - roughly, "why is Starlink allowed to double the number of objects in earth orbit?"

But, you follow it up with an unjustified comment - "with relatively large solar panels/bodies". Can you expand on this? Are these things an order of magnitude larger than the median tracked object? A factor of two?

Finally, you make a comment that doesn't follow for me:

> which by virtue of their area alone can be expected to be more visible

Is it not true that angling solar panels away from the earth to minimize the "area" relative to a ground observer is trivially accomplished?

And, also, already not really knowing the size of objects in space, I find it hard to accept that they are such significantly larger objects that they take up more of the sky. Please expand on why they are so much larger or perhaps fly so much closer to earth or perhaps have such limited maneuverability that I should be concerned.
