why do eclipses like up perfectly and yet in the days surrounding the sun isn’t partially covered as the solar bodies gradually like up?

Question

Seems odd that they go from not being near one another at all (to partially cover) to suddenly being perfectly lined up.

Answer 1

The moon moves west to east in Earth’s sky, about 13 degrees per day. The moon and sun are just half a degree across, so the time span of eclipses is short, maybe an hour or so.
