Earth and the Moon are proportional partners, and that might be rare

By using the NASA's JPL — Small-body Database Lookup, the orbit of 469219 Kamo'oalewa can be displayed alongside Earth's orbit. The orbits appear to be nearly identical but just shifted. In the bottom-left corner it provides the distance from Kamo'oalewa to Earth and to the Sun. Credit: NASA

Evidence builds that Kamo’oalewa is a chunk of the Moon accompanying Earth
