The secret of the formation of the moon, which revolves around the earth – archyde

Jakarta

As month formed is a question often asked by people curious about Earth’s natural satellites, which always glow brightly at night.

Scientists believe that the moon formed 4.5 billion years ago amid the chaos of the young solar system, with volatile matter growing and growing into planets.

There are at least three main theories about how the moon was formed:

  • Giant Impact Theory: The Apollo astronauts brought back more than 22 kilograms of rock and dust collected from the lunar surface. The samples show some striking similarities between the earth and the moon, and show nearly identical chemical and isotopic compositions
  • Formed with Earth: In this scenario, some of the matter also formed the moon, while matter was connected to the earth, and the smaller object eventually orbited its larger companion
  • Capture Theory: The moon formed in a different location outside of the solar system. Then, as it moves, it becomes trapped by the Earth’s gravity.

The giant impact hypothesis is the most popular of the three. The hypothesis suggests that the moon was formed from material ejected in a massive collision between a Mars-sized planetary body known as Theia and the young Earth, also known as Proto-Earth, right after our planet formed its original crust would have. The two papers are variations on this scenario. The debris left over from this impact is collected in orbit around the earth and bound together by gravity.

The author of this study argues that if month born from a huge impact, then it was mostly made up of material from Theia. In contrast, the earth and moon have the same composition.

“The Standard Model for the Moon requires relatively slow collisions,” said Erik Asphaug, professor at the Lunar and Planetary Laboratory.

“And that creates a moon that is mostly made up of affected planets, not proto-earths, which is a big problem because the moon has almost identical isotopic chemistry to Earth.”

But if a double collision were to occur, as quoted by Inverse, the event would be confused between Proto-Earth and Theia, which would lead to the composition of the Moon.

Why does the earth have a moon?

The earth is not the only planet forming or capturing month. These natural satellites are widespread throughout our star system.

Most of the planets in the solar system have moons in orbit:

  • Mars has two small moons, Phobos and Deimos
  • Jupiter, the largest planet, has 79 moons
  • Saturn hat 82 World
  • Uranus and Neptune are 27 and 14 months, respectively
  • Some asteroids and dwarf planets also have moons. For example, Pluto has five.

Without month, life on earth would not be the same. The moon is partly responsible for the change of the seasons on earth. The impact that produced the moon may also have caused the planet to tilt. This inclination gives the earth the change of seasons as parts of the planet move closer and farther away from the light and warmth of the sun.

month continues to help the earth maintain this tendency to this day. A 2018 study also showed that 1.4 billion years ago a day on Earth was only 18 hours because the moon was closer to our planet and affected how the earth rotates on its axis.
