Does Earth Really Have More Than One Moon? the Truth Behind Viral Claims
By Elena Rostova
Among all known co-orbital objects, asteroid 469219 Kamoʻoalewa stands apart. Discovered in April 2016 by Pan-STARRS 1 atop Haleakalā, this 40-to-100-meter body travels in a synchronized dance with Earth that has persisted for roughly a century and will continue for centuries more. It approaches no closer than about 9 million miles (14.5 million kilometers) from Earth, roughly 38 times the distance between Earth and the Moon.
The real surprise emerged during physical characterization studies conducted at the Large Binocular Telescope in Arizona. Spectroscopic analysis revealed that Kamoʻoalewa does not resemble typical carbonaceous or silicaceous near-Earth asteroids. Its reflectance spectrum matches lunar silicates returned by NASA's Apollo 14 mission almost perfectly. Dynamical simulations published by celestial mechanics specialists indicate that Kamoʻoalewa was likely blasted off the lunar surface during an energetic impact millions of years ago, escaping the Moon's gravity and settling into a stable quasi-satellite resonance. In a literal sense, Earth's most stable quasi-satellite is an exiled piece of our original Moon.
