We already told you a few weeks ago that the Earth had, temporarily, a second Moon. A small satellite that had been ejected from the Sun's orbit and captured by Earth's gravity . Its discovery was announced in February, to the delight of all astronomy fans.
Christened 2020 CD3, the tiny moon had been circling the Earth about 300,000 kilometers from our planet (just under the Earth's distance from the Moon) for at least a year, maybe longer, according to astronomers' calculations. .
Despite his closeness, he never represented a danger to us . But we will be left with the curiosity to know what was its chemical composition. At least for the moment. Scientists are working on its identification by analyzing the tonality of the mini moon to see if it could be an asteroid or perhaps a piece detached from our own Moon.
This car -sized mini moon will visit Earth again in 2044 .
