Half a dozen fragments of the moon can orbit the Earth at any time, but new research suggests before circumnavigating the Sun, but the small size and fast pace of the miniburn make them difficult to find.
When an object collides with the moon, they send a shower of material, some of which can escape into space. There may be large masses from time to time, but most move fast and are smaller than 6.5 feet (2 meters) in diameter. Most of the lunar material falls into orbits around the sun, which is more gravity and attractive. However, some debris can sometimes be drawn into orbit around the Earth before returning to circle the sun, researchers explained in a study published in the journal Icarus.
“It’s kind of like a square dance, where partners change regularly and sometimes leave the dance floor for a while,” Robert Jedick, a researcher at the University of Hawaii and lead author of the study, told Space.com via email.

Part of the moon
Although there is no official definition of the International Astronomical Union, previous studies suggest that minimoons can be at least temporarily bound to Earth, revolutionizing at least one planet, and at some point in orbit it could be nearly four times closer to Earth’s distance.
Mini-munes can come from anywhere in the solar system, but a 2018 study suggested that most come from the region of the asteroid belt between the orbits of Mars and Jupiter. However, the appearance of miniburns from the recent moon has put its findings in doubt.
In 2016, the Pan-Starrs1 Asteroid Survey Telescope in Hawaii discovered 131-328 feet (40-100 meters) near-earth objects identified as “469219 kamo’oalewa,” or “469219 kamo’oalewa.” Subsequent research revealed that the Camooareva is a slice of the moon excavated between 1 million and 10 million years ago in the crash that formed the Giordano Bruno Crater.

Earlier this year, astronomers announced that the second temporary terrestrial satellite appears to have lunar origin. The objects discovered last year (the object called 2024 PT5) look more like the moon than the asteroid.
Together, these two objects suggest that the moon may be giving birth to its own small moon. So Jedike and his colleagues decided to calculate just because there could be some moon minimen. Relying on simulations of how particles from the moon behave, they discovered that many of the particles infused into space could be captured at least temporarily by the Earth, with about a fifth of them likely to become minimal.
The new findings nominally predict that a moon-born moon in 6.5 could be turning the Earth at once. Individual objects can be modified. If it can be counted today and again in a year, some will be new objects. According to Jedicke, a typical mini-moon dances around the Earth for an average of around nine months, and these mini-men are constantly replenished from material that travels in Earth-like orbits.
However, when it comes to nailing the number of predicted miniburns, Jedick warned that uncertainty is “huge and many sizes.” This is due to many unknowns, including the size of the crater formed by the impact and the size and velocity distribution of the material discharged.
“If there were so many [temporarily bound objects]telescope investigations will probably detect a lot of them,” Jedik said. That’s science. ”
As science is based on new information, a better understanding of the identification of more moon mini-munes and their size distributions will help improve their predictions and provide new insights into the crater formation process.
Small objects, big challenges
Because of its size, small temporary moons are difficult to find. The problem is related to both size and speed. With most fragments ranging from 3 to 7 feet (1 to 2 m) in diameter, even the most seasoned instruments can have a hard time detecting them. Jedicke compares them to a car or SUV.
“Detecting objects in that size range means they must be close because they are bright, but if they are close, it also means they appear to be moving quickly across the sky,” Jedicke said. “It’s incredible that modern telescope studies have the ability to detect such small objects millions of miles away.”
In large-scale sky surveys, computers usually work to elicit movement. If the mini mune is close enough, their rapid movements could leave the trail rather than the spot on the sky image. “It’s more difficult to trail for computer algorithms to identify,” Jedick said.
But everything is not lost. A new study suggests that 2020 CD3 looks like a Catalina Sky survey for only two nights out of the approximately 1,000 nights in which the object was in range. Successful detections are good for future observations. Once an object is identified, it is easier to track because astronomers know where to look for the minimum.
Jedick said these short visitors may also have attractive commercial applications, as they may require minimal fuel to visit attractive commercial applications. Instead of flying into the asteroid belt and extracting water, minerals and other commercially desirable elements, companies were able to find ways to get something temporary when they temporarily put Earth in orbit.
From a scientific standpoint, Minimoon and his relatives “may help to clarify how the solar system is formed and continues to evolve,” Jedick said. Understanding how lunar fragments were thrown from the moon during an impact helps researchers better understand and estimate damage from the asteroid’s impact on Earth.
