SUMMARY

To observe a total solar eclipse, the Moon must align with the Earth and the Sun, allowing the Moon's umbra to fall on Earth. This alignment does not require the Moon's orbit to be nearly aligned with Earth's orbit; it can occur even if the orbits are orthogonal. For a partial solar eclipse, the Moon's penumbra, which has a wider casting, also requires the Moon to cross the direct line between the Earth and the Sun during the new moon phase.

PREREQUISITES
  • Understanding of lunar phases, specifically the new moon phase
  • Knowledge of celestial mechanics and orbital alignments
  • Familiarity with the concepts of umbra and penumbra
  • Basic astronomy terminology related to solar eclipses
NEXT STEPS
  • Research the mechanics of lunar and solar eclipses
  • Study the differences between umbra and penumbra in eclipses
  • Explore celestial mechanics and orbital dynamics
  • Learn about the historical significance of solar eclipses
USEFUL FOR

Astronomy enthusiasts, educators, students studying celestial events, and anyone interested in understanding the mechanics of solar eclipses.

Homework Statement
Does the orbit of the moon, at the time of the new moon have to lie in the same plane as the Earth's Orbit around the Sun for the Moon's shadow to fall onto the Earth ( in order to have a solar eclipse, whether it be partial, total, or annular)?
Relevant Equations
Solar Eclipse
From my understanding, for an observer to see a total solar eclipse, 1) the Moon's orbit has to be near aligned with the Earth's Orbit, 2)such that the New moon's Umbra falls on Earth, and 3) the observer must be within this cast umbra. But for a partial solar eclipse, since the Penumbra of the new moon has a wider casting, does the Moon's orbit still have to be nearly aligned with Earth's?

Umm... why?

I meant the Moon has to be in line with the Earth and Sun

That is correct, but it does not require the two orbits to be near aligned. It could still happen even with the orbits orthogonal.

Thank you, so the moon just has to cross the straight line path between the Earth and Sun during the new moon phase

Right.
