A small space rock that was standing near Earth last year and was called its temporary “Mini Moon”, which can actually be a part of the moon, which ended thousands of years ago.
The object near the heaven, known as 2024 PT5, measures about 33 33 feet (10 meters) wide. However, according to the researchers, it is not at risk of colliding with the ground for more than decades now or the next few decades. After its closest point of view on Earth, the 2024 PT5 is slowly ending in its new, more remote orbit.
But surprisingly, the orbit of the object around the sun is like the earth, which shows that the 2024 PT5 system has begun from our corners of the solar system.
Astronomers first watched NASA on August 7 using NASA’s financing, the last alert system, or using the Atlas -based Observatory in South Africa.
Despite the predictions that the teens can become a temporary mini -moon revolving around the Earth, the space rock maintained the orbit of the horse, which brought it closer, but it never entered orbit around our planet. However, it is almost specific to the Mini Mini Mini Mon because it is probably a piece of real moon.
Carita is the main author of a study about this object that was published on January 14 The letters of the astronomical journal.
“It was never really in orbit, but to describe the words here that he did what he did in the ground, his orbit change a bit from a very close view with the Earth Moon system And then, “Out of the way”, “the Criter said in an email. Such orbit is basically rare, so it should not be surprising that we have not yet had a common term for it.
In the Mona Kaya Observatory in Hawaii, Careta and her colleagues observed the item with the convenience of the Luvil Discovery Telescope and the NASA infrared telescope. Since sunlight shows the level of 2024 PT5, the team realized that it looks very similar to the lunar surface rocks.
“We had a general idea that it came from the moon, but the smoking gun came when we found out that it was rich in silicate minerals – not the kind of the kind that appears on the teens but the lunar rock. I have been found. ”
This discovery highlights a rare but growing population of Lunar Teenagrara, which shows how many times the effects on the moon have sent the rocks around the road while flying around the earth.
His team members in the Careta and Loyal Observatory, who study Kishodarrah near the ground on a nearby orbit, were already witnessing this before anyone named it as a potential mini -moon.
To ensure that the 2024 PT5 space was not a space debris, such as an old rocket, which can be found in orbit like Earth, the team studied how the object came in.
Space stones and accessories respond in different ways solar radiation pressure, or the speed of the sun’s light particles. These quantum particles, called photons, use a small force when they face objects in space. When many photons kill an item, they can fasten it or slow it down.
When photons affect the hollow rocket booster, it runs like an empty ton as it can hit the breeze, while the movement of a temptation will not be too much affected. Nasa.
Scientists at NASA’s Center for Earth Object Studies (CNEOS), who track the tensions and space debris, calculated the movement of 2024 PT5 and determined that it was really a space rock instead of debris. –
In a statement, NASA’s Jet Propulsion Laboratory Post Documentary Fellow, who worked with CNOS researchers, said in a statement, “Space debris and space stones move in a slightly different way in space.” “The human -made debris is usually relatively light and pushed around with sunlight pressure. It does not move 2024 PT5 in such a way that it is far less than the space debris.
Robert Jedke, a specialist at the University of Hawaii Institute for astronomy, believes that 2024 PT5 is a lunarian of the study because the authors of the study have “a complete analysis of all reasonable options “” Jedak was not involved in a new study.
“This speculation that reduces items like 2024 PT5 on the Earth -like orbit like Earth, or can have chips away from the moon, is absolutely reasonable.” “It is expected that some things were launched by the moon with the influence of tear or dimension.
Several studies about this item have been published since its discovery in August, and a September’s paper Carlos de La Fivent Marcos was one of the earliest researchers at Mathematics Science at the University of Concepts, Madrid. He said that most of the research has come to the same way that had 2024 PT5 lunar debris. Da La Foenta Marcos was not involved in the new research.
“Immediately after the discovery. Later, CNEOS Director Paul Chodas said that the dynamics of the 2024 PT5 can be explained only if this effect was a piece of the moon issued during the event. “Da La Funer said Marcos.
In September, Da La Fuan Marcos’s dissertation suggested that Objun Arjuna is part of the Kishodarrah belt, made of small teens, in which the earth orbit are orbit around the sun. Da La Funer Markos said the possibility was made of lunar debris “is really an unexpected discovery.”
Due to the lack of weather on Kishorgara, it can only be a few million years old, Karita said. Too much He said that the reflection of the surface of the Kishodarrah is the best matching of the luminous hills, or at most levels of the moon, the best matching of the rough, rough region.
If scientists can connect the lunar teens on the moon with specific citers, the space stones can further disclose the material as well as the material below it.
So far, 2024 PT5, like the land, is the only second item in orbit which is lunar. Astronomers found Kishodarrah 469219 Kamovaleva in 2016, which was also removed from the lunar surface after hitting the moon.
The discovery of Kamovaleva was encouraged by scientists who were desperate to find more, but no other candidate has emerged until 2024 PT5.
“If there is anything, it is easy to make yourself believe that it is an outlet or difficult to explain,” said Carita. “If there are two, then there is a whole population awaiting recognizing and studying it.”
Careta and her colleagues estimates that 16 of the lunar -e -Nashd -16 have already met and are waiting for confirmation.
“The total size and characteristics of the population are directly related to how many times the moon produces these small rocks – this is the information after which we want to go as soon as the population grows.”
More sensitive telescopes that come online in the future, such as Vera Rubin Observatory (in Chile) and a NEO surveys in space, will usually be able to detect more teens, including small, unconscious stone through the moon. Yes.
“Before we go to the telescope, we have to be safe to know how we can eliminate dozens of candidates’ items with a lunar orbit,” said Carita. “It is like a needle search in a grass, except the needles do not appear to be much different from the grass unless you take them in front of the telescope.”
