To match the brightness of the sun, around 400,000 moons would be required.
That quantity may appear to be very astonishing at first, but keep in mind that the moon does not create its own light; rather, it reflects the light of the sun. And not particularly well. "The brightness of the Moon depends on the exact angle between the Earth, Moon, and Sun... the brightness of a Full Moon is typically reported as a magnitude around -13, roughly 14 magnitudes or 400,000 times fainter than the Sun," according to Sky & Telescope. That implies the moon has a lot of work ahead of it if it wants to be as visible as our brightest star.
