A mini moon that will soon bid farewell to Earth may actually be a tiny piece of the larger moon – one that has ruled the skies for longer than humans have roamed the planet. A follow-up study has taken a closer look at the bus-sized outer rock to better understand what it’s made of, how fast it spins, and where it moves. A team of researchers says the mini moon is something between an S-type asteroid, made of silicates and metals, and a V-type like Vesta, the second largest object in the main asteroid belt. Although the results are not conclusive, they suggest the mini moon, officially called 2024 PT5, has lunar origins, matching powder collected by the Soviet Union’s Luna 24 robotic mission in 1976, followed by samples from NASA’s Apollo 12 mission in 1969. Both The specimen came from the Maria, a dark lunar region covered in ancient, hardened lava. The article, whose authors include two astronomers who discovered the mini moon in August, proposes that 2024 PT5 may have emerged from a crater formed over the past 1 million years or so. This manuscript is under peer review for publication in Astronomy & Astrophysics Letters. This is PT5’s 2024 trajectory around Earth, from 25 years before to 25 years after the current epoch, according to the latest study. Asteroid 2024 PT5, which makes a complete rotation every hour, has been flying partially around Earth since September 29 and will depart on November 25, according to the manuscript. Since its arrival, this visitor has caused a stir for many, with many arguing that calling this newly arrived little rock a moon is a mistake. Even famed space communicator Neil deGrasse Tyson weighed in on the controversy, calling the mini-moon labels “click bait.” Despite the debate, Carlos de la Fuente Marcos, one of the founders based at the Universidad Complutense de Madrid in Spain, is comfortable with the term, citing literature to support its use in his paper. “What we have here is a typical example of the use of different scientific criteria,” he told Mashable. “This is a temporary satellite of Earth, call it a mini moon if you like.” What is clear is that asteroids are often affected by Earth’s gravity in this way, and most pass by without completing a full journey. Most are thought to come from the Arjuna asteroid belt, a group of rocks concentrated near Earth discovered in the early 1990s. These asteroids complete one revolution around the sun each year, and the Earth and moon actually pass through the middle of the belt, de la Fuente Marcos said. In fact, rock capture from such groups may be so likely that these objects may become mini moons again in the future. But compared to the mini moons of the past, 2024 PT5 is a short one. In July 2006, a visitor dubbed RH120 stayed in orbit around Earth for a year before being ejected in July 2007. Astronomers believe the one that left in May 2020 may have been circling the planet for several years. Despite their frequency, mini-lunar episodes should not be dismissed as commonplace, said Antonio Maudes, CEO of Light Bridges, which manages several robotic telescopes in Spain’s Canary Islands. The company’s Twin Two Meter Telescope provided observational data for the research team. “You probably won’t find a more interesting object than this in the solar system because they are so close to Earth, and they will return,” he told Mashable. “That is cool.” The company is developing a project in Spain dedicated to monitoring cislunar space, the region around the Earth and moon. The goal is to improve astronomers’ statistical understanding of the origins, trajectories, materials, and rotational speeds of minimoons. Such information is not only useful for monitoring potentially dangerous rocks that could hit Earth. Maudes thinks it could also be useful for commercial exploitation. Venture capital entrepreneurs have long touted the space mining industry for valuable minerals. Arjuna asteroids are much closer than those in the main asteroid belt, between Mars and Jupiter, perhaps making them a more practical destination. Adolfo Nemirovsky, a physicist and advisor to Light Bridges, likened this nearby asteroid to a Home Depot – a relatively convenient place to pick up materials to build a lunar base and supply space missions. Even though 2024 PT5 is on its way out now, many astronomers are grateful that it opened the public’s eyes to realize that things are spinning around the world all the time. “You get the feeling that it’s an empty space between here and the moon, and there’s nothing there – it’s not like that at all,” Maudes said. “There are a lot of different forces at play here.” NASA plans to observe 2024 PT5 with the Goldstone Solar System Radar in California in January 2025. At that point, the object will be very far away – about five times farther than the moon, about 239,000 miles – before continuing its trajectory around the sun.
Is It a Moon? The Quirky Case of 2024 PT5
Well, it seems we’ve just discovered a new member of Mother Nature’s dysfunctional family! A mini moon is set to say goodbye to Earth, and, honestly, it’s the most exciting thing to happen since someone decided to put pineapple on pizza. This little rock, officially named 2024 PT5, could actually be a tiny chunk of our beloved Moon, which has been lording over our nights like a celestial diva for longer than we’ve been able to form coherent sentences. Imagine moonlight so beautiful, it could inspire a cheesy rom-com!
What’s the Deal with 2024 PT5?
Now, for the science enthusiasts among you, scientists have taken a magnifying glass to this “mini moon” – measuring its spin, composition, and whereabouts. Spoiler alert: it spins like a disco ball every hour! Incredibly, this modus operandi may just reveal that our little buddy is a hybrid. It sits somewhere between an S-type asteroid (the silicate and metal variety) and a V-type, like Vesta – which sounds like an artist you might hear at a bohemian café, doesn’t it?
The study suggests a family reunion with the Moon isn’t just a poetic notion. It aligns with materials collected by the Soviet Union’s Luna 24 mission and NASA’s Apollo 12 – those vintage trips that scream, “We went to the Moon before it was cool.” So, 2024 PT5 might just be a long-lost cousin of our big Moon, emerging from a crater formed not too long ago – about a million years if we want to be precise. If that’s not a stunning backstory for a celestial body, I don’t know what is!
The Rumble Over Naming
Enter Neil deGrasse Tyson, the man, the myth, the astrophysics legend, who weighed in on this moniker controversy like he was critiquing a Broadway show. He called the term “mini-moon” nothing short of “click bait.” Well, who knew the cosmos came with a media strategy? But hold your horses; our friend, Carlos de la Fuente Marcos, who discovered the mini moon, argues it is, indeed, a mini moon based on scientific literature. “Temporary satellite” or “moonlet,” folks, we’re here for the drama! It’s like a reality show where even celestial bodies get involved in the naming game. Will 2024 PT5 appear on the next season of “Keeping Up with the Planets”?
Catching Rocks with Earth’s Gravity
Now, hold onto your telescopes because this is where things get thrilling! These asteroids often find themselves on a rollercoaster, thanks to Earth’s gravitational pull. It’s like they’re playing hide-and-seek, swinging around, and sometimes popping back. Most consider the Arjuna asteroid belt their hangout spot – not too far, not too close, just like your cousin’s apartment that you can tolerate visiting but wouldn’t want to live in.
2024 PT5 is just one of many cosmic visitors we’ve had. Remember RH120? That little dude stuck around for a year before making a graceful exit. Meanwhile, astronomer Antonio Maudes from Light Bridges likens this to a “Home Depot” of asteroids, ready to supply materials for a lunar base. Who knew space rocks could also inspire DIY projects?
Looking Ahead
As we bid adieu to 2024 PT5, NASA is gearing up for a rendezvous in January 2025 using the Goldstone Solar System Radar, hoping to catch a glimpse of it five times farther than the Moon. So, when you look up into the night sky and see nothing but stars, remember, they’re all up there, doing their own thing, just waiting for someone to name-drop.
In the end, while this mini moon may be short-lived, it’s thrown a spotlight on the wonders of our universe. So the next time someone tells you it’s just empty space between us and the Moon, remind them of the beautiful chaos swirling around us. You never know when a disco ball-sized stone with a complex family history might pass through.
Stay tuned, folks! The Universe is playing hard to get, and we’re just along for the ride. Catch you on the next orbit!
