He added that the mini-moon appears to have been orbiting our planet since it was first captured by Earth’s gravity three years ago. Early observations also suggest it is small enough to fit in just about any garage or shed, with an estimated diameter between 2 and 3.5 meters (about 6 – 11 feet).
The photo obviously doesn’t match the actual size of this “mini-moon” but you get the idea.
There was another one a few years ago, by the way. It stayed a few months and then got booted out of orbit.
