A Doomed Primordial Planet Brought Life To EarthFebruary 10, 2021
Our moon is the largest object in the Earth’s night sky, glowing when it reflects the light of our star. But how did the beautiful and charming moon of the Earth appear? The most common theory of moon formation suggests that our Moon was born when a primitive protoplanet the size of Mars called Teia crashed into our old planet billions of years ago and was turned into powder. This catastrophic collision sent the wreckage into orbit around our young planet. The wreckage, consisting of both the materials of the doomed Teya and the badly damaged ancient Earth, eventually hardened, forming a single body – the moon. In January 2019, a team of astronomers reported new findings that most of the major elements of life on Earth, including most of the carbon and nitrogen in our bodies, most likely came from another planet doomed by the original protoplanet on which Teia was located. The moon is born. An article describing this new study is published in the January 23, 2019 issue of the journal Science Advances.
According to a new study by petrologists at Rice University in Houston, Texas, the collision occurred about 4.4 billion years ago, when our solar system was still young.
“By studying primitive meteorites, scientists have long known that the Earth and other rocky planets in the inner solar system are variable. But the timing and mechanism of volatile emissions are hotly debated. Our scenario is the first one that can explain this timeline. And delivery is in line with all geochemical data,” said study co-author Dr. Rajdeep Dasgupta in a press release from Rice University on January 23, 2019.
The Earth’s moon has long been a source of fantastic and magical myths and legends. He was also a subject of poetry as well as an ancient symbol of feminine. Indeed, the accompanying world of Earth inspired beautiful stories about romantic love and madness – the word “crazy” comes from the word “moon.” There are fascinating stories and delightful children’s stories about “The Man on the Moon” and “Moon Rabbit” that seem to be engraved on the lunar surface.

There are more than 100 satellites orbiting the eight main planets of our solar family. Most of the many moons in our solar system are icy, relatively small objects containing a small amount of rocky material, and surround a quartet of giant gaseous planets in the coldest outer region of our solar system. Giant planets – Jupiter, Saturn, Uranus and Neptune – are covered with layers of gas and layers of gas orbiting numerous moons and shiny icy moons. On the contrary, a solid quartet of small planets of the inner solar system – Mercury, Venus, Earth and Mars – is almost completely devoid of moons. Mercury and Venus are not, and Mars revolves around a pair of tiny shapeless little moons called Phobos and Deimos, which are probably asteroids that have left the large asteroid belt between Mars and Jupiter. The wandering duo in the shape of potatoes traveled too close to the gravity of Mars during their long journey through interplanetary space, experiencing the transition from a sea of migratory asteroids to the satellites of a large planet.
In the warm, well-lit inner region of our solar system, only the Earth orbits a large moon – and it is the fifth largest moon in our Sun’s family.
The moon is a natural satellite that orbits another body that orbits its own star. The moon is held in place by both the gravity of its host and its own gravity. Some planets have moons; some don’t. It is now known that several asteroids orbit their small moons, and some dwarf planets, such as Pluto, are also surrounded by moons. One of Pluto’s five moons, Charon, is about 50% the size of Pluto. It has been suggested that Charon is in fact a large part of Pluto itself, which was recently deceived after a strong collision with another migratory object. Because Charon is about half the size of Pluto, two small worlds are sometimes classified as double planets.
However, the theory of a giant impact is considered the most likely explanation for the birth of a large moon on Earth. When the tragedy of Teia, the size of Mars, struck Earth billions of years ago, a part of the ancient crust was launched into space as a result of the explosion. This primitive catastrophe has thrown countless small howing moons into the sky above our old planet. Some of this material eventually became trapped in orbit about 4.5 billion years ago, where it eventually turned into one big moon, earth, under the influence of gravity.
Until Galileo Galilei discovered the four Galileo moons of Jupiter in 1610, the Earth’s large moon was considered the moon, as it was the only known moon of the existing one. The discovery of a quartet of Galileo satellites – Io, Europe, Ganymede and Callisto – raises the question in perspective. The Earth’s moon is not the only one in our solar system. In addition, there is evidence that exomones revolve around some exoplanets that orbit stars outside our Sun.
However, the Earth’s moon is the largest moon in our solar system compared to the size of the host planet. For this reason, the Earth and its moon are sometimes seen as a double planet, similar to Pluto and its larger moon Charon. The Earth’s moon is also one of the densest natural satellites in the family of our Sun – just behind the inner Galilee moon of Jupiter Io.
Being the fifth largest moon in our solar system, only Ganymede (Jupiter), Titan (Saturn), Callisto (Jupiter) and Io (Jupiter) are larger than earth’s moon.
Despite the fact that Teiya brutally finished, she died not in vain. For many years it has been recognized that the doomed Teiya made possible the appearance of life on our planet. This is because he is responsible for creating a comfortable home for living things. The moon, born at the site of Theia’s crash, softens the Earth’s oscillations around its axis, creating a stable climate. The Earth’s moon is also the source of ocean tides, which form the rhythm that humans have guided since ancient times.
Teija died for a reason.
A team of petrologists from Rice University gathered evidence from a combination of experiments with high temperature and high pressure conducted in Dr. Dasgupta’s lab, which specializes in studying geochemical reactions occurring in extreme heat and pressure deep inside the planet.
In a series of experiments, the study’s lead author and PhD student Damanvir Grewal collected data to test the theory that Earth’s volatiles were brought to our ancient planet as a result of an initial attack by a germ protoplanet whose nucleus was richly gray. The sulfur in the heart of the donor planet is important because it could explain the mysterious array of experimental evidence of nitrogen, carbon and sulfur found in all parts of our planet except its nucleus.
“The nucleus doesn’t interact with the rest of the Earth, but everything above it – the mantle, the crust, the hydrosphere and the atmosphere – is all interconnected. Material cycles between them,” Grewal explained January 23, 2019, Rice University Press.
The model explaining how the Earth got volatiles is called the “late galvanic coating” theory. According to this model, the fragments of ephemeral relics, rich in primary matter, from the outer solar system arrived after the formation of the Earth’s nucleus. Although the isotope characteristics of volatiles on our planet correspond to these ancient primitive objects known as carbon chondrites, the elemental ratio of carbon to nitrogen is not. The iron core of the Earth, which geologists call loose silicate land, consists of about 40 parts of carbon per part of nitrogen. This is about twice as much as the 20-1 ratio observed in carbon chondrites.
Simulations of high pressures and temperatures occurring during the formation of the nucleus, as was modeled in Grewal’s experiments, tested the theory that the planet’s sulfur-rich core could eliminate carbon or nitrogen – or both. This scenario will leave a much larger percentage of these elements in silicate in mass compared to Earth.
