Facts About Mercury
Facts About Mercury – Mercury is a planet close to the sun, which is correctly pronounced Mercury in Arabic. Mercury or Mercury is located at a distance of 57 million and 924 thousand kilometers from the Sun and because of this proximity, its orbits around the Sun rotate faster than any other planet. An elusive planet that is not easy to see. Because like an arrow dropped from a bow, it orbits the sun with our majesty, and this rotation lasts only 88 days. Mercury was known in the late Samaritan period about 5,000 years ago. Mercury is sometimes called both the morning star and the evening star. Greek astronomers knew they were both a planet. Heraclitus believed that both Mercury and Venus revolved around the sun, not the earth.
The physical nature of Mercury – Facts About Mercury
Due to Mercury’s close proximity to the Sun, its surface reaches a temperature of 450 degrees Celsius. And since it does not have a specific atmosphere, its temperature drops to 170 degrees Celsius at night and fluctuates around 600 degrees Celsius, which is the largest change in the solar system. Mercury is only slightly larger than the Moon. And since it does not have an atmosphere to prevent impact, its surface has a lot of cracks and fissures. About 4 billion years ago, a 100-kilometer-diameter meteorite struck Mercury, hitting it hard and causing a deep rift. The rift could cover the entire state of Texas, and just one more blow could split the planet in two. Although researchers speculate that there is water in the northern part of the planet, it is relatively remote Mercury is the second heaviest planet after Earth, with a metal core 3,600 km in diameter, or 75% of its diameter. The composition of the metal core and the abundance of volatile objects have been a mystery to researchers for many years. Collaborate with the schools on body science and anatomy, holding classes and workshops.
1. If your weight on Earth is 31 kg, you will weigh only 12 kg on Mercury because it is smaller than Earth and has less gravity.
2. Because the planet is brighter in the morning and at sunrise, they are called morning stars.
3. Mercury has no air or water.
4. During the day, Mercury’s temperature rises to 400 degrees Celsius, while at night it drops to -170 degrees Celsius.
5. A solar day on Mercury, which lasts from noon to noon, is equal to 176 Earth days, while an astronomical day, the time of 1 rotation from a particular point, lasts 59 Earth days.
6. Mercury is almost locked into the Sun, which slows the planet’s orbit over time to match its rotation around the Sun.
7. Although it is the smallest planet in the solar system, it is one of only five planets visible to the naked eye. In comparison, the Earth is 12,742 km away from the equator, while this distance is 4,879 km on Mercury.
8. Although Mercury is a small planet, it has a very high density. In fact, each centimeter has a density of 5.4 grams, while the density of the earth is slightly higher. This is because Mercury is made up entirely of heavy metals and rocks.
9. As the planet’s metal core cools and contracts, wrinkles form on its surface. Scientists call these folds Lobate Scarps, and these folds can be miles high and thousands of miles wide.
10. NASA scientists have recently discovered that Mercury’s solid metal core could melt.
11. Mercury is the second hottest planet, the first hot planet is Venus, although Venus is farther from the Sun.
12. Unlike other planets that can repair themselves through geological processes, Mercury’s surface is full of craters created by the collision of millions of asteroids and comets.
13. Any opening with a diameter greater than 250 km is called a basin.
14. The Polaris Basin is the largest Mercury crater, about 1,550 km in diameter, and was discovered in 1974 by the Mariner 10 probe.
15. To date, only two spacecraft have visited Mercury. Between 1974 and 1975, Marine 10 traveled to Mercury three times. On August 3, 2004, the spacecraft was sent to Mercury from Cape Canaveral Air Force Base, the second spacecraft to visit Mercury since the mid-1970s.
16. The exact date of the discovery of Mercury is not known, but it is even older than what is said. It is said that the Sumerians discovered it around 3000 BC.
17. Contrary to popular belief at the time that Mercury and Venus revolved around the earth, Heraclitus, a pre-Socrates Greek philosopher, believed that the two revolved around the sun.
18. Unlike Earth, Mercury has no atmosphere, so it can not trap the sun’s heat.
19. Mercury temperature fluctuations are the largest temperature fluctuations in the solar system. During the day the temperature can change by more than 600 degrees Celsius or 1100 degrees Fahrenheit.
The size of Mercury compared to Earth – Facts About Mercury
20. Radar observations made in 1991 showed that the holes of the north and south poles of Mercury may have been placed on ice because these areas are always in the shade and cold.
21. Some astronauts believe that ice has penetrated into the planet since the asteroids struck. Others believe that the gas was trapped on the planet but escaped and froze near the poles.
22. The Clarice Basin was created by an asteroid about 4 billion years ago. The asteroid is said to be about 100 kilometers wide and hit Mercury with a force of 1 trillion bombs, each of which is 1 megaton.
23. The diameter of the metal core is about 75% of the diameter of the planet. Mercury’s outer crust is only about 500 to 600 kilometers wide.
24. The first spacecraft sent to Mercury, Mariner 10, concluded that the planet has its own magnetic field.
25. The force of Mercury’s magnetic field is only 1% of the Earth.
26. The magnetic fields generated by the solar wind often affect the magnetic field of Mercury and produce strong magnetic tornadoes.
27. Mercury orbits the Sun at a speed of 180,000 kilometers per hour, making it the fastest planet in the solar system.
28. It orbits the sun in an elliptical orbit. At its closest point, it is 47 million kilometers from the Sun, and its closest point is called the Pavilion.
29. Mercury is 70 million kilometers away from the Sun, and its farthest point is called Ophelia.
30. When Mercury is closest to the Sun, the Sun appears three times larger than what is seen from Earth.
31. As the sun rises on Mercury, the sun rises and sets again and rises again. At sunset, the sun goes down, rises again, and sets again.
32. Every 100 years, Mercury can be seen 13 times as it crosses the surface of the sun. This event is visible from the ground.
