Eclipses are phenomena that occur due to the position between the moon, the earth and the sun.

Sometimes these stars line up, blocking out some of the sunlight that illuminates the Earth or the moon. Eclipses can be lunar or solar.

Lunar eclipse

The lunar eclipse happens in the Full Moon phase. It occurs when the earth is between the sun and the moon, which passes through the shadow region of the earth. The Earth at this time blocks the sun's rays that illuminate the Moon. The Earth's shadow casts on the Moon, covering it partially (partially eclipse) or fully (total eclipse).

Solar eclipse

Occurs when the moon is between the sun and the earth, ie in the phase of New Moon and all are aligned in one line. On this occasion, the moon blocks the sun's rays that illuminate part of the earth.

The solar eclipse may be partial for some regions. This phenomenon occurs at least twice a year; however it rarely occurs in the same place on earth.

The influence of the moon on the earth

The moon is the main cause of tidal phenomena. The force of attraction between the Earth and the Moon and between the Earth and the Sun (to a lesser extent) causes the rise and fall of sea level. The rise is high tide or high tide. The descent is at low tide or low tide.

The tides happen because the gravitational force is greater on the side of the earth that is closer to the moon than on the opposite, farther side.

But the influence of the gravitational pull of the moon and planets on the human body can be neglected by the influence of planet Earth and even much lighter but much closer bodies.
