With the illustrious name Temporarily Captured Object 2020 CD3, Earth's new moon might not be entertaining a manned landing at any time in the future. Especially since it's only a few feet wide. But the tiny sattelite, spotted February 15 with the Catalina Sky Survey in Arizona, is something to celebrate all the same.
Our new moon is probably between 1.9 and 3.5 metres across, or roughly the size of a car, making it no match for Earth’s primary moon. It circles our planet about once every 47 days on a wide, oval-shaped orbit that mostly swoops far outside the larger moon’s path.
The orbit isn’t stable, so eventually 2020 CD3 will be flung away from Earth. “It is heading away from the Earth-moon system as we speak,” says Grigori Fedorets at Queen’s University Belfast in the UK, and it looks likely it will escape in April.

Astronaut David Scott re-created, in 1971 during the Apollo 15 mission, Galileo’s “falling bodies” experiment by dropping a hammer and feather on the moon at the same time. Simply, both fell at the same rate because there was no air resistance. screengrab via Wonders of Physics/YouTube (Digg)
On Tuesday evening, the night before NASA astronaut Bob Behnken was set to launch into orbit about a SpaceX Falcon 9 rocket and Crew Dragon capsule, he launched his own rocket from Florida’s Atlantic Coast.
Even in horrible economic times, a few simple rules hold unshakably true. And one of those rules is that if you possess an in-demand skill, you’ll always find work — and often, at a top market salary, to boot. If you understand Big Data and how to find order from the chaos of massive stockpiles […]
We live in a disposable era. If you can’t fix a broken item with a wrap of duct tape, there’s a very strong likelihood that its next destination is the trashcan. However, that probably leads to a trigger-finger death sentence for many household items that could be saved with just a bit more ingenuity. Before […]
Right tool for the right job. You probably heard a parent or grandparent say it at least once at some point. And it’s true in so many cases. If you spot a small tear in your living room curtains or near to hem a pair of pants, you can always use the good old fashioned […]
