In a discovery that sounds like something out of a science fiction movie, astronomers Earth will temporarily capture a new 'mini-moon', it was discovered.This asteroid is called 2024 PT5, and it will be trapped in Earth's gravity from September to November 2024.
The recently discovered asteroid 2024 PT5 is on a trajectory that will lead it to become a small satellite. The Earth briefly passes over it before continuing its journey around the Sun. Although temporary, this phenomenon is an important event in the study of near-Earth objects.
Researchers Carlos and Raul de la Fuente Marcos, Complutense University of MadridThey were responsible for this discovery. Using observational data and mathematical models, they came to this conclusion. PT5 from 2024 will follow a horseshoe-shaped orbit around the Earth..
This type of temporary capture is not entirely new. In 2006, Earth was observing asteroid RH120 for about a year. Most recently, in 2020, asteroid 2020 CD3 also briefly became a mini-moon.
When and why will it happen?
Asteroid 2024 PT5 has orbital properties that make it particularly interesting. Its semi-major axis is about 1012 AU away, With a very low eccentricity of 0.021, indicating a nearly circular orbit.Furthermore, its inclination is only 1.52 degrees, which puts it in an orbit similar to Earth's.
During its short stay as a small moon, 2024 PT5 It will provide valuable data on asteroid dynamics and gravitational interaction with Earth.Scientists hope to use this information to improve orbit prediction models and better understand how these objects are captured and released by Earth's gravity.
The asteroid will orbit our planet for about two months, To become a “mini-moon” between September 29 and November 25, 2024.
The capture of small moons is a phenomenon that occurs due to the complex gravitational dance between Earth and the nearest asteroids. When an asteroid gets close enough to Earth, it can be temporarily captured. in orbit around our planet before being ejected back into interplanetary space.
The PT5 2024 study will help better understand the dynamics of these objects. Developing Planetary Defense StrategiesIn case a dangerous asteroid approaches Earth. Moreover, they could be future targets for space exploration missions.
International cooperation and monitoring
Asteroid 2024 PT5 It was discovered on August 7, 2024 by the Earth-based Asteroid Impact Alert System.It was observed using the instrument in Sutherland, South Africa, and its discovery and observation were made possible thanks to international collaboration and the use of advanced telescopes.
Notes from multiple facilities It was used. To track the asteroid's orbit and predict its temporary capture. across the Earth, highlighting the importance of continuous monitoring of the sky.
Near-Earth asteroids are numerous, however. Most of them do not pose an immediate threat.Studying them is crucial to our understanding of the solar system and to protecting our planet.
When 2024 PT5 approaches Earth, Astronomers will be watching to capture detailed images and data of its passage.This event will be a unique opportunity to observe the little moon in action and learn more about these mysterious space travelers.
Implications and the future
Such events, in which a small body gains negative geocentric energy for weeks or a few months, are relatively frequent, with several occurring every decade. On the other hand, extended capture loopsrareThe Earth experiences one every ten to twenty years or so.
The reason for expelling these objects from the Earth is the force of the Sun's gravity. When 2024 PT5 fulfills its role as a mini-moon, it will return to orbit around the Sun.the remaining part of the Arjuna asteroid belt.
Unfortunately, It will not be visible to most skywatchers. It is too small and dim for amateur telescopes and binoculars.You need a telescope with at least 30 inches in diameter and a CCD or CMOS detector, as the human eye is not enough.
Researchers Intends to make spectroscopic and optical observations in 2024 PT5 To better understand its nature. For now, prepare yourself for an unparalleled celestial spectacle, and stay tuned for news about this exciting astronomical event.
