A composition about a solar eclipse of 600~800 words

Today, I got up early and brought my binoculars, sunglasses, and camera.

Maybe you have to ask: Where to take so many things? Hee hee, give it a try first.

Today seems to be different from usual. The cool breeze blows and I feel refreshed. My father and I came to Yaodu River in Hexi Province like lightning (an exaggeration). We chose a place, took out the telescope, and put on the Put on sunglasses, haha, you should have guessed it by now, right? right! I am watching a total solar eclipse. Do you know what a total solar eclipse is? Well, I might as well open up the conversation!

A solar eclipse, also known as a solar eclipse, is an astronomical phenomenon that only occurs when the moon moves between the sun and the earth. At this time, for some areas on the Earth, the Moon is in front of the Earth, so some or all of the light from the Sun is blocked, so it appears as if part or all of the Sun has disappeared. Solar eclipses only occur during the new moon, when the moon and sun are in conjunction. A solar eclipse is a very rare phenomenon. The rarer of the four types of solar eclipses is a total solar eclipse, because people in that area can only observe the solar eclipse when the moon's umbra is projected on the earth's surface. A total solar eclipse is a very magnificent natural scene, so it often attracts many tourists to go overseas to watch the total solar eclipse. For example, the total solar eclipse that occurred in Europe in 1999 attracted many tourists to go specifically to watch it, and some travel agencies launched itineraries specially designed for these tourists. In ancient times, humans lacked astronomical knowledge and believed that solar eclipses were caused by the Tengu eclipsing the sun, or that they symbolized the coming of disaster, so they held rituals during solar eclipses. But in modern society, this meaning of solar eclipses has gradually been abandoned by people. The "seasons" of solar and lunar eclipses. The solar eclipse must occur on the first day of the new lunar month. At this time, the moon is located between the earth and the sun. However, because the sun's orbit (ecliptic) and the moon's orbit (ecliptic) are at an angle of 5°9, a solar eclipse does not occur every new moon. When a solar eclipse occurs, both the sun and the moon All must be near the "yellow-white node" (ascending node or descending node). For solar and lunar eclipses to occur, the new moon and full moon must appear within a certain limit of the yellow and white nodes. This limit is called the "eclipse limit." Calculations show that for a solar eclipse, if the new moon is within a range of about 18 degrees near the intersection of the ecliptic and the ecliptic, a solar eclipse may occur; if the new moon is within a range of about 16 degrees near the intersection of the ecliptic and the ecliptic, then There must be a solar eclipse happening. For a lunar eclipse, if the moon is within a range of about 12 degrees from the intersection of the ecliptic and the ecliptic, a lunar eclipse may occur; if the moon is within a range of about 10 degrees from the intersection of the ecliptic and the ecliptic, a lunar eclipse will definitely occur. . Since there are two intersections of the ecliptic and the ecliptic, and these two intersections are 180 degrees apart, there are two periods of time in a year where solar and lunar eclipses may occur. Both periods are called "eclipse seasons", and they are half a year apart. . The sun moves eastward about 1 degree on the ecliptic every day. Since the eclipse limit of a solar eclipse is about 18 degrees, it takes about 36 days for the sun to travel from 18 degrees west of the intersection of the ecliptic and the ecliptic to 18 degrees east of the intersection of the ecliptic and the ecliptic. days, that is to say, each eclipse season lasts for 36 days. For a lunar eclipse, its eclipse limit is about 12 degrees, so each eclipse season only has 24 days. A total solar eclipse occurs because the sun is close to a point where the moon's orbit intersects with the earth's orbit, and the moon is at its closest point to this point. An annular solar eclipse occurs because the sun is close to a point where the moon's orbit intersects with the earth's orbit, while the moon is at the farthest point from this point.

Okay, that’s it for the chatterbox, let’s continue talking about how I watched the total solar eclipse!

After my dad and I were ready, we started watching, one minute, two minutes... I couldn't sit still. My dad saw it and said, "Look, a piece of the sun is missing!" I quickly looked up, my God! Really, a small piece of the originally round sun was missing. Looking further, it was not good, the sun was covered by dark clouds. I waited patiently, but it didn't work anymore, and it seemed that my father couldn't wait any longer... That's it. , my father and I went home in a hurry again. After returning home, I was bored. I turned on the computer, played for a while, and went to the toilet. Oh my God!!! I made a cry of up to 12 decibels. What's wrong? The originally blue sky turned pitch black, and people were shrouded in darkness. I fumbled to turn on the light, and ran to the balcony to take a look. There was no sun in the sky. It could be said that a bottle of ink had been poured on the world. Gradually, the sky slowly turned white, the sun gradually showed its smiling face, and the total solar eclipse ended like this!
