There are many articles coming out having to do with, "Earth is going to have two moons," space.com has stated the following: "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." It is also said that this "mini moon" will be around fro a couple weeks while some articles claim it to be up to two whole months before this "mini moon" returns back trailing throughout space. Other claims were stated by the same article saying: "Marcos explained that in order to become a mini-moon, an incoming body has to approach Earth at a close range of around 2.8 million miles (4.5 million km) and slowly at about 2,200 mph (3,540 km/h)." and "Under these conditions, the geocentric energy can become negative, and the object becomes temporarily bound to Earth." What else do we know about this asteroid stuck in our atmosphere and do we really have evidence that it will be our "mini moon" for two whole months?
