What you need to know about Earth's new, temporary mini-moon
Briefly

Professor Carlos de la Fuente Marcos from Universidad Complutense de Madrid described the Arjuna asteroid belt as a collection of space rocks on similar orbits to Earth, about 93 million miles from the sun. He explained that some of these objects can come quite close to Earth and travel slowly enough to temporarily enter our orbit."
De la Fuente Marcos mentioned that the velocities of these objects are around 2,200 miles per hour, allowing them to orbit Earth temporarily if they pass within about 2.8 million miles."
Some scientists propose that the asteroid we discovered could possibly be a fragment of Earth's moon, dislodged after a prior impact, providing fascinating clues about its history and relation to our planet."
