Wait for the year 2638 if you missed seeing a comet of the same type as Halley.

The evening of March 11 with an image of Comet 12P/Pons-Brooks. In Doi Intanon, Chom Thong District, Chiang Mai Province, published by the National Institute for Astronomical Research (NARIT) or SDR provided information that comet 12P/Pons-Brooks is classified as a short-period comet, meaning its orbital period is less than 200 years. It has an orbital period around the Sun of 71 years, similar to Halley's Comet (1P/Halley), which also has a short orbit around the Sun. It orbits close to the sun and will be closest on April 23. It will receive more energy and radiation from the sun. This causes a large cloud of dust and gas to spread out. As a result, the comet will be at its peak brightness. It can even be seen with the naked eye in the night sky. If we miss this time, we may have to wait 71 years, or 2638, which is arguably one generation before we can see the comet. 12b/Pons-Brooks once. As for Halley’s Comet, it will orbit closer to the sun every 75 years, and its last appearance was in 1986. Therefore, Halley’s Comet will orbit again this year.

Comet 12P/Pons-Brooks was first discovered by French astronomer Jean-Louis Pons in 1812 and rediscovered in 1883. (1883) by William Robert Brooks, American astronomer “Hence the origin of the comet's name. 12P/Pons-Brooks It is named after the astronomers who discovered the two.

As for the “green fireball” above the sky on March 4, it turned out to be a “fireball meteor,” large in size and very bright, with a brightness similar to that of the planet Venus. As for March 6, it was an “explosive meteor.” (Polidi) Because the brightness is equivalent to the brightness of a “full moon” or an explosion in the air. This time, the meteor explosion occurred twice about one hour apart, and the first time it had a blue head. The tail is green, and the second time his head is orange and the tail is green. Each vision lasts about 10 seconds.

There are also above-the-sky phenomena or objects above the sky that can occur in many different ways, and “meteors” are caused by cometary debris and dust. Or the asteroid gets damaged and collides with the Earth's atmosphere at very high speeds. Friction and combustion occur in the atmosphere at an altitude of 80-120 kilometers, causing light to be emitted from the meteorite atoms of different wavelengths. The color of the meteorite comes from the light emitted by the meteorite’s metallic atoms. This will vary according to the chemical composition. The surrounding air molecules make the meteorite only have a green glow of light with the purple tone made of calcium atoms. As for the light, the blue tone made of iron atoms. Magnesium atoms and nickel will give blue light and the green part of the sodium atom gives orange-yellow light while the molecules are in the Earth's atmosphere. It has oxygen and nitrogen atoms as its components. Which will give off red light? Hot meteors, which tend to produce primarily red and green light, depend on the altitude of the Earth. “Meteorites” burn up as they quickly descend into the Earth's atmosphere. Therefore, it has the fastest movement among all creatures. It only lasts from a few seconds to a fraction of a second. If the sky at that location is not observed from the beginning, it is almost impossible to operate the camera to record the image in time.

As for meteorites, they have the same origin as meteors. Therefore, it is a term given to the masses of meteorites that survive to reach the Earth and are called meteorites. Every day, approximately 44-48.5 tons of meteorites fall to the Earth daily, but most of the areas are remote areas, so people cannot. It can be seen

Comets are large icy bodies that orbit the sun in the solar system. It has a distant origin. But there will come a time when it orbits the inner solar system where Earth is. When comets orbit close to the Sun, they may evaporate. It leaves behind small clouds of gas and ice fragments along its orbit. It appears as a long tail, so it is called a “comet.”

Rockets are man-made objects. Rockets are powered by leaving gas behind. Therefore, it should be noted that it resembles a “tail” drawn over a long distance. But the missile may have been high and out of the atmosphere. Hence there is no combustion.

Information from scientists at NASA's Meteorite Environment Center explains the reason for the discovery. The “meteor” is mostly at the beginning of this year, and in addition to being found during the “meteor shower” phenomenon that occurs at a clear time and day every year, statistics indicate that from mid-February to mid-April every year. It is a period in which the rate of viewing fireballs in the evening increases for observers in the northern hemisphere by about 10-30 percent higher than other periods. This period is called the “meteor season.” Throughout the year, if we can view the sky from dusk until dawn, you can expect Seeing approximately 10 random meteors per night, and during the “meteor shower” phenomenon, dozens to hundreds of meteors can be seen.
