When a solar eclipse occurs, it is considered one of the greatest cosmic phenomena, as a solar eclipse occurs when the moon falls between the sun and the earth on the same line, while a lunar eclipse occurs when the moon falls in the area known as the earth’s shadow that prevents the sun’s rays from reaching it, and during the Marj event we will talk in detail of the occurrence of a solar eclipse.
When a solar eclipse occurs
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 so that it partially or completely hides the sun from the planet earth, and this causes its shadow to fall on the earth. The surface of the earth, and the sun, where the sun moves in the sky through a fixed path, it passes through what is called the orbit of the sun, and similarly, the moon moves along a fixed path around the earth, but the path of the moon is inclined by five degrees from the path of the sun, and this is the reason for the absence of an eclipse of the sun Each time, the moon is between the sun and the earth, and the eclipse occurs once. , for about half a year.
Types of solar eclipse
There are three types of solar radiation, namely:
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 last from two minutes, and can last up to seven minutes. Gradually, after about an hour has passed, the moon covers the sun with its rays until the total eclipse occurs, and at this stage the diameter of the sun reaches about 1,390,473 km, which is about 400 times more than the diameter of the sun. The moon, which is 3476 km long, but the moon is about 400 times closer to the earth than the sun.
Algerian solar eclipse
A partial solar eclipse occurs when part of the moon’s shadow falls on the surface of the earth, that is, it obscures part of the sun from the surface of the earth, and the region in which a partial lunar eclipse occurs remains covered by the shadow that gives a faint glow, and these areas are the polar regions, and in such cases, Regions farther from the poles, and those within the umbra, only a small part of the edge of the Sun that hides the Moon can be seen.
Annular solar eclipse
The annular eclipse is a type of partial eclipse of the sun, in which the moon blocks part of the sun from the surface of the earth, and the annular eclipse can last for a maximum period of 12 minutes and 30 seconds, and the similarity between the annular eclipse and the total eclipse is that the moon appears to pass in the middle of the sun, but The difference between them lies in the fact that the moon is too small to completely cover the sun.
Phases of a solar eclipse
The next stages during an eclipse are as follows:
- Full sun: The stage of the full sun is the stage before the eclipse, as well as under it, where the sun appears as a complete circular disk, and the area where the sun’s rays appear at this stage is called the area of the light ball.
- First contact: The first contact phase is the first phase of the eclipse phase, so that the moon begins to touch the sun’s disk in the correct area, and appears in the northern hemisphere.
- Partial Eclipse: In this phase, the Moon blocks part of the sunlight from the Earth’s surface.
- Second contact: The second contact occurs when the moon approaches the sun and completely covers it from the surface of the earth.
- Total Eclipse: A total eclipse occurs when the moon is completely covered.
- Third Contact: The third contact phase occurs when the moon begins to gradually move away from the sun’s disk.
- Sunshine Restoration: In the sunshine recovery stage, sunshine begins to reappear moments after the third contact.
- Fourth conjunction: The fourth conjunction phase or the final phase of a solar eclipse, and it starts from the moment the moon touches the edge of the sun.
We’ll come to the end of our article on when a solar eclipse occurs, highlighting the types of solar eclipses, and the phases of eclipses, ranging from a full solar eclipse to the fourth call.
