A total solar eclipse. Earth's orbit around the Sun is also elliptical, with the Sun closest at perihelion, and farthest away at aphelion. © Time and Date AS 1995–2021. The visibility of the tool will be geofenced to the general region of the eclipse, and will only be visible to users in the box bounded by latitude -70 to 3 and longitude -100 to -25. If the Moon is not near a lunar node during New Moon, the Sun, Moon, and Earth do not align in a straight or almost straight line, and a solar eclipse cannot occur. The Moon's orbit is slightly tilted around Earth, so the Moon doesn't always pass into Earth's shadow. Knowing this, we were quite astonished when during totality of the 2017 solar eclipse, we suddenly could observe mountain tops well beyond the visual range of that day, before and after totality. As we can see here that moon blocks some of sun rays to reach on the small part of earth and thus moon forms a shadow on earth during solar eclipse. Total Lunar Eclipses are much more common that Total Solar Eclipses, as a great circle of the Earth has a much greater circumference that that of the Moon.

Tags: Question 4 . Since the Moon's umbra is always surrounded by a penumbra, the eclipse appears partial if you are just outside the spot where the umbra hits. The total phase of the eclipse can only be seen from within the Moon's umbra, which only covers a small area on the Earth's surface.
