KOMPAS.com- A solar eclipse is one of the natural phenomena that always attracts people’s attention. There are two types of solar eclipses that are considered the most special, namely total solar eclipse and ring solar eclipse.
Basically, a solar eclipse is an optical phenomenon that occurs when the moon is between the Earth and the sun, then the moon looms over the Earth.
Quoted from Space, Monday (29/3/2021), a solar eclipse can only occur during the new moon phase, when the moon passes right between the sun and the earth, and its shadow falls onto the Earth’s surface.
There are several types of solar eclipses and they are always an interesting phenomenon. These include total solar eclipse (GMT) and ring solar eclipse (GMC).

So, what is the difference between a total solar eclipse and a ring solar eclipse?
The process of a solar eclipse, whether it is a total solar eclipse or a ring solar eclipse, depends on several factors.
Total solar eclipse is one of the rare celestial phenomena. No wonder the presence of a solar eclipse is always considered special.
When this eclipse occurs, the sun’s 864,000 miles in diameter is completely 400 times larger than Earth’s satellite, the Moon, which measures only about 2,160 miles.

But the moon also happens to be about 400 times closer to Earth than the sun, the ratio varies due to the two elliptical orbits.
As a result, when the orbital planes intersect and their distances are parallel, the new moon can be completely visible, closing off the solar disk.
There are actually two types of shadow or umbra, namely the part of the shadow where all sunlight is blocked. The umbra is a dark, slender cone, surrounded by a penumbra, a lighter funnel-shaped shadow where some sunlight is blocked.
As reported Kompas.com, Monday (14/12/2020), the phenomenon of a total solar eclipse occurs depending on the distance between the three objects, namely the Earth, moving in an elliptical orbit around the Sun, and the Moon moving in an elliptical orbit around the Earth, so that the distance between these celestial objects changes.

When the Sun is closest to Earth, and the Moon is approaching the farthest distance, in the sky the Moon will appear smaller than the Sun.
When does a total solar eclipse occur?
Even though total solar eclipse is a rare phenomenon, it does not mean that this optical phenomenon is rare.
Because, on the contrary, an average total solar eclipse can occur every 18 months or about one year to two years, which occurs somewhere on Earth’s surface.

This phenomenon of solar eclipses is the most frequent or more common occurrence. The phenomenon of a ring solar eclipse occurred last year in the Indonesian sky.
What is a ring solar eclipse?
Reported Kompas.com, Last June 6, 2020, a ring solar eclipse occurred when the Sun, Moon and Earth were exactly aligned and at that time the disc of the Moon that was observed from Earth was smaller than the disc of the Sun.
“As a result, when the peak of the eclipse occurs, the Sun will appear like a ring, which is dark in the middle and bright at the edges,” quoted from the official website of the Meteorology, Climatology and Geophysics Agency (BMKG).

When this solar eclipse occurs, the condition of brightness or light during the day decreases dramatically, causing a dark atmosphere, as if it were at night.
There are two kinds of lunar shadows that are formed when this ring solar eclipse occurs, namely the antumbra and the penumbra.
In the area that the antumbra passes, the observed solar eclipse will be a ring solar eclipse.
Meanwhile, in areas that receive a penumbra, the observed eclipse phenomenon is in the form of a partial solar eclipse.
