The angular diameters of the Sun and the Moon are very close to each other
It is a fun coincidence that the Sun's physical diameter is about 400 times greater than that of the Moon but that latter happens to be about 400 times closer to us than the Sun. Thus they appear to be of similar size. The fact that the Moon appears to be at least as large as it does results in the fact that there can be total solar eclipses.
I have seen a total solar eclipse once. That was on the 22th of July 1990. A friend of mine who is an amateur astronomer and I traveled to Joensuu in Eastern Finland by train from Tampere. We were stayed as guests at the home of a former neighbour of my parents' in Hammaslahti to the south of Joensuu. The Sun was about 5 degrees above the horizon when the eclipse took place at about 5 am. Our former neighbour drove us to the shore of the Lake Höytiäinen, a large lake to the north of the town of Joensuu. We had welding glasses as a light filter for my friend's camera and to be held by hand over our eyes.
