De la Fuente Marcos and his colleagues plan to observe 2024 PT5 to collect more data and details using the Gran Telescopio Canarias and the Two-Meter Twin Telescope, both on Spain’s Canary Islands.

Analyzing the object, around 10 meters (33 feet) in diameter, astronomers from the Complutense University of Madrid, Carlos de la Fuente Marcos and Raúl de la Fuente Marcos, found that it was on ...

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).

"There are multiple lines of evidence suggesting that this asteroid may have a lunar origin," Carlos de la Fuente Marcos, discovery lead author and a professor at the Universidad Complutense de ...

Earth’s moon will soon have some company — a “mini moon.” The mini moon is actually an asteroid about the size of a school bus at 33 feet (10 meters).

The asteroid is expected to enter Earth’s orbit Sunday and lurk there until Nov. 25, just over 56 days, Marcos said. Earth as seen from the surface of the moon by the Apollo 11 Command Module in ...

S tarting next week, the moon, Earth’s closest celestial body, will be joined by a new neighbor: a second moon.. From Sept. 29 until Nov. 25, astronomers calculate that 2024 PT5— which is what ...
