Evening of March 11 with an image of comet 12P/Pons-Brooks. On Doi Inthanon, Chom Thong District, Chiang Mai Province, which the National Astronomical Research Institute (NARIT) or S.D.R. published and provided information that Comet 12P/Pons-Brooks It is classified as a short-period comet, meaning it has an orbital period of less than 200 years. Comet 12P/Pons-Brooks It has an orbital period around the Sun of 71 years, similar to Comet Halley (1P/Halley), which also has a short orbit around the Sun. Comet 12P/Pons-Brooks It is orbiting closer 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 brightest. Until it can be seen with the naked eye in the night sky. If we miss that time, we may have to wait 71 years, or in the year 2638, which could be said to be one generation before we can see the comet. 12P/Pons-Brooks once. As for “Halley’s Comet”, it will be closest to the sun every 75 years, most recently appearing in 1986. Therefore, “Halley’s Comet” will orbit again this year. 2604 B.E.
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 name comet. 12P/Pons-Brooks Named after the astronomers who discovered the two people.
As for the “green fireball” above the sky on March 4, it was found to be a “Fireball meteor” (Fireball), large and very bright, with a brightness similar to that of Venus. March 6 was an “explosive meteor” (Bolide). Because the brightness is equivalent to the brightness of “Full moon” or an explosion in the air This time the exploding meteor occurred 2 times approximately 1 hour apart. The first time it had a blue head. The tail is green, the second time it has an orange head and the tail is green. Each sighting lasts approximately 10 seconds.
There are also phenomena above the sky or objects above the sky that can occur in many different ways. “Meteors” are caused by the debris and dust of comets. or asteroid Hurt and collide with the earth’s atmosphere at very high speeds. There is friction and burning in the atmosphere 80-120 kilometers high, causing the meteor’s atoms to emit light in various wavelengths. The color of the meteor comes from the light emitted from the meteor’s metal atoms. This will vary according to the chemical composition. and surrounding air molecules Makes the meteor not only have a green glow For light with a purple tone Made from calcium atoms As for the light, the blue tone Made from iron atoms The magnesium and nickel atoms It gives a blue-green light. sodium atom part Gives an orange-yellow light while the molecules in the earth’s atmosphere It has oxygen and nitrogen atoms as its components. which will give a red light Hot meteors, which tend to produce primarily red and green light, depend on the height of the earth. “Meteors” burn from the speed of their descent into the Earth’s atmosphere. Therefore, it has the fastest movement among all objects. It only lasts from a few seconds to a fraction of a second. If the sky is not observed at that location from the beginning, it is almost impossible to turn the camera to record the image in time.
As for meteorites, they have the same origin as shooting stars. Therefore, it is a term used for the lumps of meteors that survive to reach the ground and are called meteorites. Each day approximately 44-48.5 tons of meteorites fall to the earth per day, but most of the areas are remote areas so people cannot. Can be seen
Comets Large icy bodies orbiting the sun in the solar system. It has a distant origin. But there will be a time when it orbits into the inner solar system where the 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 may be noted that it looks similar to a “tail” drawn in a long way. But the rocket may have been high up and out of the atmosphere. Therefore there is no combustion.
Information from scientists at the Meteorite Environment Center of the National Aeronautics and Space Administration (NASA) explains the reason for the discovery. “Meteor” often at the beginning of this year In addition to being found during the “meteor shower” phenomenon that occurs at a clear time and day every year, statistics show that From mid-February to mid-April every year. It is a period in which the rate of fireball sightings in the evening for observers in the northern hemisphere increases by about 10 – 30 percent higher than in other periods, and this period is called “meteor season”. Throughout the year if we can watch the sky From dusk until dawn, you can expect to see approximately 10 random meteors per night. During the “meteor shower” phenomenon, dozens to hundreds of meteors can be seen.
