Description of the event called sun and moon eclipse, explanation and differences between the solar and the lunar ones, visible effects of both.


Difference between eclipse of sun and moon

When we talk about an eclipse, we generally refer to an astronomical event that occurs when a celestial body stands between a light source and another body, causing the latter to enter its shadow cone.

During an eclipse of the Sun, the Moon stands between it and the Earth.


We speak of partial eclipse when the shadow of the moon covers only part of the sun.

In the case of total eclipse, the solar disk instead remains completely covered, albeit for a short period of time, by the shadow of the Moon and for this reason it is no longer visible from the earth, with a consequent change in temperature and light that gives rise to moments of dark and cold.

In the case of the lunar eclipse, the Earth is positioned along the imaginary line that divides the Sun from the Moon itself and this prevents the sun's rays from illuminating the moon, which seems to disappear for a few moments, as it is no longer visible.
