How do you know that???
Look it up yourself.
I said "trillions of stars", okay that was hyperbole. Yet there may be, including estimates of the ones in galaxies we've observed. Yet the count we can now make? Close to a billion or so.
Most modern catalogues are generated by computers, using high-resolution, high-sensitivity telescopes, and as a result describe very large numbers of objects. For example, the Guide Star Catalog II has entries on over 998 million distinct astronomical objects. Objects in these catalogs are typically located with very high resolution, and assign designations to these objects based on their position in the sky.So exactly what is 200/1,000,000,000?(Wikipedia, here)
