Jakarta –
Solar eclipse occurs when the moon is between the earth and the sun. If this happens, some of the sunlight that normally reaches the earth’s surface is covered by the moon.
Although the moon has a smaller size, the moon’s shadow can completely shield the sunlight. This is because the moon has a distance of 384,400 km closer to the earth than the sun which has a distance of 149,680,000 km.
Solar eclipses can only occur when the moon is on a new moon and when the moon is near one of the vertices of its orbit.
Do you already know? types of solar eclipses? If not, see the following explanation quoted from the website of the State University of Surabaya (Unesa):
1. Total Solar Eclipse
Solar eclipse Total occurs when the sun is completely covered by the moon. This is because the moon is near the earth in its longitude orbit. A total solar eclipse is only seen from the area of the Earth’s surface that is exposed to the umbra shadow.
Total solar eclipses are very rare. Perhaps one can only witness once in a lifetime.
A total solar eclipse is a beautiful sight but also dangerous for the eyes. When the sun’s rays are completely covered by the moon and only the corona (a circle of light that surrounds the sun) then it is safe for us to see without any protection for our eyes.
The total solar eclipse can be seen using special glasses or it is safer to see through TV broadcasts.
2. Partial Solar Eclipse
This solar eclipse occurs when the moon covers only part of the sun. When a partial solar eclipse occurs, we can see it directly upwards. A partial solar eclipse does not damage the retina of the eye.
3. Ring Solar Eclipse
A ring solar eclipse occurs when the moon covers only part of the sun and the rest of the sunlight forms a luminous ring around the moon’s shadow known as a ring.
Around the area where a total solar eclipse or an annular solar eclipse occurs, there is always a much larger area. This is because the annular solar eclipse is in the penumbra of the moon.
Area solar eclipse some can extend for nearly 5,000 km on each side of the overall track.
