NARIT National Astronomical Research Institute posted a message via Facebook to “Halley’s Comet” that “During this time many people may have heard the song Comet Halley of the band fellow fellow. Of course, this comet really exists. And it is one of the most famous satellites in history. NARIT would like to take everyone to get to know Halley’s Comet more through this song. “During the time there was a star orbiting in space, From that day, I saw the world differently.” Comet Halley (Halley’s Comet), officially named 1P/Halley, is the most famous comet. And there is evidence recorded of sightings for more than 2,000 years. It is named following “Edmond Halley (Edmond Halley), an English physicist and mathematician. Who was the first to calculate the period of Halley’s Comet in the year 1705 AD – Continue reading the article below In 1687, it was the year that “Isaac Newton (Isaac Newton)” published a work called “Philosophiæ Naturalis Principia Mathematica” or as we know it in name The famous “Newton’s Law of Gravity” that many people have probably learned regarding in high school physics. At that time, Halley was considered one of Newton’s closest people. Halley was interested in the gravity of Jupiter and Saturn. How would the gravitational pull of these two gas giant planets affect the orbits of comets? In 1705, Halley used records of comet positions from the 16th to the 17th centuries to calculate using the law of Newton and found that there were 3 comets that had appeared in 1531, 1607 and 1682 that had the same orbital properties. He therefore concluded that This is the same comet that returns close to Earth every 74 – 79 years. Halley’s first observation and recording of this comet was in 1682. And Halley predicted that This comet will pass close to Earth once more in 1758. “The calendar from now on is for counting the days. Clocks are for counting the minutes.” It turns out that in 1758, a comet actually appeared in the sky with the naked eye, but in the end, Edmund Halley never had the opportunity to see this comet with his own eyes. myself for the second time Since his death in 1742, this comet was the first to be classified as a short-period comet. (The orbital period is shorter than 200 years.) And in honor of Edmund Halley, this comet was named “Halley’s Comet” itself. “There are still a thousand love songs waiting to be shared with you.” Advertisement – Continue reading the article below the song. “Halley’s Comet” is becoming famous during this period. It’s not the first work of art to be associated with Halley’s Comet. As mentioned above, This comet has been recorded since ancient times, more than 2,000 years ago. Ancient works of art have been found, such as records from ancient China from 200 BC, the Bayeux Tapestry, a 70-meter-long leather tapestry from the 11th century, the Eadwine Psalter, a book It is related to the Psalms of Christianity in the 12th century. In those days, it was believed that Comets are a bad omen. Because whenever a comet appears in the sky It will always lead to defeat in war from all educational information from the past to the present. Astronomers found that Halley’s Comet has a diameter of 11 kilometers, an average orbital period of 76 years, and an elliptical orbit around the Sun. Each cycle has a different orbital period. Because their orbits are disrupted by the gravity of other planets, comets are by nature “dirty ice cubes” in space, made up mostly of easily sublimable molecules such as water, methane, ammonia and carbon dioxide. Mixed with debris and dust every time a comet orbits close to the sun. Comets will receive much higher amounts of radiation. The molecules of these substances sublimate into gases that disperse into space. has the opposite direction to the sun A beautiful comet’s tail was born. “Can I stay in the rest of your life? I want to open my eyes and see you until the last day.” Comet Halley’s last orbit came close to the sun in February 1986, and from calculations it is expected that The next comet will pass close to the Sun in mid-2061, so in another 38 years we are likely to see one of the brightest and most beautiful comets yet. Come back to appear in the sky for us to admire once more. Advertisement – Continue reading the article below. Although Halley’s Comet orbits for us to see every 76 years, every time it moves in Radiation from the sun causes the comet to gradually lose mass, becoming smaller by 1-3 meters each cycle. Until finally, when the ice mass dissolves completely, Halley’s Comet would not have the beautiful tail we’ve seen in the past. It became just a dark rock in space. Or it may simply disintegrate into dust particles that continue to orbit around the sun. As Halley’s Comet orbits, it dumps rocks and dust into space. When the world orbits past Earth’s gravity pulls these rocks and dust particles into the atmosphere. Burning like a meteor It is the origin of the “Orionids” meteor shower that occurs regularly during October every year. In 2023, the Orionids meteor shower will have its highest falling rate on the night of the day. On October 21 until the morning of October 22, the center of the distribution is in the constellation Orion, with a falling rate of approximately 20 stars per hour.
