Could you imagine a mini-Moon floating through our solar system?
Some researchers say a near-Earth asteroid, named Kamo`oalewa, may actually be a large piece of the Moon that somehow broke away from our lone satellite.
Scientists call Kamo`oalewa a quasi-satellite, which is a category of asteroids that orbit the Sun, but still pass relatively close to the Earth. Astronomers know very little about quasi-satellites because they are typically very faint in the night’s sky, making it hard for telescopes to spot them.
However, after missing a chance to examine the asteroid in 2020 due to COVID-19 lockdowns, the team discovered the missing piece of the puzzle in April 2021. 💪
Study authors found that Kamo`oalewa’s orbit is very similar to the Earth’s, but with a slight tilt in it.
