This month, Earth will grab itself a second moon in the form of the tiny asteroid 2024 PT5, according to Space.com.

Unlike the moon, Earth's primary companion which has accompanied our planet for around 4 billion years, this "new mini-moon" will stick around for just two months before it heads back to its home in an asteroid belt trailing our planet and orbiting the sun.

A team of scientists well-versed in the study of so-called "mini-moon events " identified the forthcoming gravitational capture event. They spotted the peculiar dynamic properties of 2024 PT5 as they routinely monitored newly discovered objects for potentially interesting behavior.

"The object that is going to pay us a visit belongs to the Arjuna asteroid belt, a secondary asteroid belt made of space rocks that follow orbits very similar to that of Earth at an average distance to the sun of about 93 million miles (150 million kilometers), research lead author and Universidad Complutense de Madrid professor Carlos de la Fuente Marcos told Space.com. "Objects in the Arjuna asteroid belt are part of the near-Earth object population of asteroids and comets."

Marcos explained that some of these objects in the Arjuna asteroid belt can approach Earth at a close range of around 2.8 million miles (4.5 million km) and at low velocities of around 2,200 miles per hour (3,540 km/h).

"Under these conditions, the geocentric energy of the object may grow negative, and the object may become a temporary moon of Earth. This particular object will undergo this process starting next week and for about two months," he added. "It will not follow a full orbit around Earth.

"You may say that if a true satellite is like a customer buying goods inside a store, objects like 2024 PT5 are window shoppers.
