Viewed from the earth, the sun and the moon appear to have pretty much the same size. The apparent size (radius) is defined as arcsin(R/h) where R is the true radius of the celestial body, and h is the distance to the celestial body.
For the sun, R=695,000 km and h=150,000,000 km.
For the moon, R=1,700 km and h=300,000 km.
You would need to put 200 suns (or moons) next to each other, to create a ring of suns (or moons) stretching in the sky, from North to South, with no gap.
By contrast, you would need 300,000 times more of our closest star (outside the solar system) to create the same continuous ring of stars.
(by the way, the answer to the original question is: the moon and the sun look pretty much the same when you compute the apparent size with the arcsin formula)
