October 25-partial solar eclipse
October 25-partial solar eclipse
"Partial solar eclipse (partial solar eclipse) is a phenomenon in which the moon forms a shadow on the earth between the earth and the sun. The shadow of the moon can be divided into three parts: umbra, penumbra and pseudo-umbra. The orbit of the moon around the earth and the orbit of the earth around the earth can be divided into three parts. The orbit of the sun is not a perfect circle, so the distance between the sun and the moon and the earth is close and far. Therefore, the observer sees that the sun is partially covered by the moon in the penumbra, which is called a partial solar eclipse; , the observer sees that the sun is completely covered by the moon in the umbra range, which is called a total solar eclipse; there is a halo around it, which is called an annular solar eclipse.
When the moon orbits the earth to the point where the sun and the earth almost rise and fall with the sun, the moon cannot be seen from the earth, which is called a new moon, and a solar eclipse occurs during the new moon. The cycle of New Moon is about 29.53 days. But not every 29.53 days a solar eclipse occurs because the plane of the moon's orbit around the earth and the plane of the earth's orbit around the sun do not exactly coincide, with an average angle of 5°9' between the two. So a solar eclipse will only occur when the Sun is within a certain angle from the intersection of the two orbital planes. "
"On October 25th, there will be a second partial solar eclipse of 2022. It will be visible from most of Europe, North Africa, the Middle East and western Asia. The best viewing location is central Russia, where about 75% of the sun will be covered. live.
