(NBC) – A new ‘mini-moon’ is temporarily orbiting the earth.
It was first spotted by scientists at the University of Arizona on February 15th.
The mini-moon, called ‘2020 cd3,’ is about 6 to 11 feet across.
Experts believe it entered the earth’s orbit three years ago.
One of the scientists that discovered the mini-moon, Kacper Wierzchos, says it is “just the second asteroid known to orbit the earth.”
