Jakarta – Total solar eclipse is a natural phenomenon that occurs once every 18 months and it takes hundreds of years to witness it in the same place. However, the peak of the eclipse only lasted for a maximum of 7 minutes. Why is that?
In a period of three decades, total solar eclipses occurred in several parts of Indonesia for three times, namely in June 1983, October 1995, and March 2016. The next total solar eclipse will occur on December 4, 2021. A number of regions such as Antarctica, South Africa, and The Atlantic can witness this eclipse.
Understanding Total Solar Eclipse
A total solar eclipse is a celestial phenomenon that occurs due to the closed disk of the sun by the disk of the moon which causes the moon to appear as large or even larger than the sun. Launch Space, when this condition occurs, the moon will cast an umbral shadow on the earth’s surface.
The umbra is the part of the shadow where all sunlight is blocked. The umbra is dark and slender conical in shape. The umbra is surrounded by the penumbra, which is a lighter, funnel-shaped shadow where the sun’s rays are partially obscured.
The shadow will cover a third of the entire planet in a few hours. If we are in the right location, we can witness the shrinking of the sun’s disk into a crescent moon as the dark shadow of the moon covers the sun.
The Process of a Total Solar Eclipse
A solar eclipse occurs when the moon moves between the earth and the sun. This movement can cause total solar eclipse, partial solar eclipse, annular solar eclipse, and hybrid solar eclipse.
Reported from the site NASAA total solar eclipse occurs when the moon covers the sun completely. In this condition, the position of the sun, moon, earth are in a straight line. This position will cause the sun’s light to be completely covered by the moon’s shadow. The closing of the sun occurs because the position of the moon is near the earth when crossing its longitude orbit.
A total solar eclipse only lasts a fairly short time. Totality can last for 7 minutes 31 seconds. However, the majority of total solar eclipses occur much shorter than this time, about less than 3 minutes.
In short, the duration of a total solar eclipse is due to the shadow of the moon moving at a speed of 1,700 km/hour. The moon takes 27.3 days to orbit the earth. However, the moon’s orbit is on an incline compared to the Earth’s orbit around the sun. Thus, a total solar eclipse occurs on Earth approximately once every 18 months.
This phenomenon can change the movement of other planets including the behavior of animals. The brighter stars and outer planets, as well as various animals returned to their nests. This is a response to the decrease in light levels and air temperature caused by total solar eclipse.
