*Elon Musk will completely destroy this effort with "Starlink".* (May he burn in Hell for all eternity).

@Reed Julius I tried that service and it downloaded a key-logger virus and tried to steal my banking info. So no thanks. NEVER use that service.

We just use a super wide-angle telescope and look for objects that are moving - like that asshole Musk's starlink satellites.

I don't really understand the numbers. If they don't know how many objects are why they give a percent of known objects?

We also know the gravitational mass by the effects on other objects. It's how we know how massive "Planet 9" is, even though we can't see it [yet]. (It could be a ring of objects, or a single planet, or a small black hole. All have the same gravitational mass).

It is a known unknown. A how many X in volume Y question where volume Y is very large. You can estimate it by taking a small part of volume Y call it y and measuring how much x there is. Then say the volume you measure y is 1% of volume Y and you count 100 x then you can estimate X is 10000.

It has happened before. And with "starlink", we will lose the ability to see these forever.
