The Moon's passage over the Sun's disk
Visually, during a similar ring-shaped eclipse, the Moon passes over the Sun's disk, but it is smaller in diameter than the Sun and cannot completely hide it.
At the maximum phase of the eclipse, the Sun is covered by the Moon, but a bright ring of the uncovered part of the solar disk can be seen around the Moon. The sky during an annular eclipse remains bright, no stars appear, and it is impossible to observe the Sun's corona.
The Moon has no atmosphere, so we can see the clear boundaries of the satellite during its transit around the Sun.
