Back in early September of 2024, two astronomers in Spain discovered an asteroid orbiting the moon. This asteroid, dubbed “2024 PT5”, was found to be roughly 33 feet long, or about the size of a school bus. Thankfully, the asteroid doesn’t pose a threat to Earth, and should only stick around until November 25th, before slingshotting back into space.
A similar thing happened back in February of 2020, where an asteroid, named “2020 CD3”, appeared in Earth’s orbit. This asteroid was only about 6 to 11 feet in diameter, and was in Earth’s orbit for more than a year before heading back out into space.
And, before that, an asteroid named “2006 RH120” was captured by Earth’s gravity, which it does every few decades, was seen in June of 2006 and stayed around until September of 2007.
These “Mini Moons” are quite common; they usually only stick around for a few months to a year, and are rarely ever visible to the naked eye. Usually, you have to use a telescope to view them. These Mini Moons are never dangerous to us or the planet, and usually make for a spectacular telescope view.
It’s not too late to see our newest Mini Moon! Break out the telescope and be amazed by the wonders of outer space!
Also, in other news, the Harford County Astronomical Society is sponsoring and Open House at the Observatory, where they will teach you how to use telescopes, etc. on December 7th at 7pm, and it’s free! Hope to see you there!
