What is required for a solar eclipse to occur regarding the ecliptic?
Answer
The Moon must cross the ecliptic plane at the correct phase
Because the Moon's orbit is tilted by approximately 5 degrees relative to the ecliptic, it does not cross this plane during every orbit. A solar eclipse requires the Moon to be in the correct phase and to pass through one of the nodes, which are the specific points where the Moon orbit intersects the ecliptic plane. If the Moon is not at one of these nodes during a new moon phase, it will pass above or below the Sun rather than blocking it.
