When does the phenomenon of a solar eclipse occur? Eclipses and eclipses are considered one of the greatest cosmic phenomena, as a solar eclipse occurs when the moon is between the sun and the Earth in a straight line, and a lunar eclipse occurs when the moon falls into it. An area known as the Earth’s shadow that prevents sunlight on it, and we will talk through it in detail about the phenomenon of a solar eclipse.
When does a solar eclipse occur?
A solar eclipse is a natural cosmic phenomenon that occurs during daylight hours, when the moon is in a straight line between the sun and the earth, partially or completely covering the sun from planet earth, causing its shadow to fall on earth. The surface of the Earth, and this is precisely the reason for the occurrence of the phenomenon of a solar eclipse, where the sun moves in the sky along a certain path through which it passes what is called the orbit of the sun. The reason is that a solar eclipse does not happen every time it happens. Between the sun and the earth, but eclipses happen once every six months.
Types of solar eclipse.
There are three types of solar eclipses
total solar eclipse
A total solar eclipse occurs when the moon is in a straight line between the sun and the earth so that it completely blocks the sun’s rays, and the total eclipse can be from two minutes and can last up to seven minutes, and the total eclipse phase begins with the phase of the partial eclipse, so that the moon begins to gradually cover the sun’s disk, After about an hour, the moon covers the sun completely to occur a total eclipse. At this stage, the diameter of the sun is about 1,390,473 km, or about 400 times the diameter of the moon, or 3,476 km, but the moon is closer to the Earth about 400 times than the sun.
partial solar eclipse
A partial solar eclipse occurs when part of the moon’s shadow falls on the surface of the Earth, that is, it covers a part of the sun from the Earth’s surface, and the area where the partial eclipse of the moon occurs is covered by a shadow that gives weakness. glow, and these regions are polar regions, and in such cases, regions far from the poles, within darkness, only a small part of the edge of the sun is hidden by the moon.
Annular solar eclipse
An annular solar eclipse is a type of partial solar eclipse in which the moon blocks part of the sun from the surface of the earth. An annular eclipse can last for a maximum of 12 minutes and 30 seconds. The similarity between an annular eclipse and a total eclipse is that the moon appears to pass through the middle sun. The difference between them is that the moon is too small to cover the entire disk of the sun.
Phases of a solar eclipse
The sun goes through several stages during an eclipse, and they are as follows
- Full Sun The stage of the full sun is the stage before and after the eclipse, where the sun appears as a complete rotating disk, and the region in which the sun’s rays appear during this stage. The field is called photovoltaics.
- First contact The first contact phase is the first phase of the eclipse phase as the Moon begins to touch the disk of the Sun on the right side and also appears in the Northern Hemisphere.
- Partial Eclipse During this phase, the Moon blocks some of the sunlight from the Earth’s surface.
- The second contact The second contact occurs when the Moon is close to blocking the Sun and completely blocking it from the Earth’s surface.
- A total eclipse occurs when the moon completely blocks the sun.
- The third contact The third contact phase occurs when the moon begins to gradually move away from the solar disk.
- Sunlight Recovery In the sunlight recovery phase, sunlight begins to appear again a few moments after the third contact.
- Fourth Contact The fourth contact phase or the final phase of a solar eclipse, and it starts from the moment the moon touches the edge of the sun.
Here we come to the end of our article, When a Solar Eclipse Happens, where we shed light on the types of solar eclipses and the stages of the eclipse from total solar to fourth contact.
