If you were hoping to see the “mini moon,” you’ve probably been disappointed. But experts say the asteroid was an important milestone in planetary defense research.

A second moon has officially entered Earth’s orbit — sort of. Although it’s being called a “mini-moon,” the object is actually an asteroid named 2024 PT5. It has been temporarily captured by Earth’s gravitational pull.

A new mini-moon the size of a city bus will soon be circling our planet and hanging out in our skies until Thanksgiving week. An asteroid named 2024 PT5 will enter Earth's orbit this week, get caught there from Sept.

You may have heard by now about Earth getting a second moon starting next week. I am going to be honest with you right out of the gate - this is not going to be as exciting as it sounds. First, let's start with what is happening.

Earth will briefly host a new visitor, asteroid 2024 PT5, from September 29 to November 25. Originating from the Arjuna asteroid belt, this mini-moon was detected by NASA in August. Although it won't be visible to the naked eye,

Though referred to as a mini-moon, 2024 PT5 won't complete a full orbit around Earth. Instead, it will be a “temporarily captured flyby,” circling around 25 percent of the planet's surface before heading off again into the solar system. These brief encounters are common, and many mini-moons don't stick around long enough to form a stable orbit.

On Sunday, Sept. 29, Earth captured a new "mini-moon" called 2024 PT5. The bus-size asteroid is expected to orbit our planet for 57 days, but is too small to be visible to amateur skywatchers.

The asteroid will remain in Earth’s orbit from now until Nov. 25, when it will exit and continue its journey through the solar system. “There’s no way for small telescopes t

A second moon has officially entered Earth’s orbit. As of September 29th, the mini-moon began circling our planet. Although it’s being called a mini-moon, it’s actually an
