An asteroid has been trailing Earth around the sun since 100 BC, astronomers estimate. The space rock at first appears to be another moon, but it's actually orbiting the sun and not Earth. That makes this asteroid a "quasi-moon" or "fake moon." Scientists first discovered the space rock, called 2023 FW13, in March using the Pan-STARRS observatory in Hawaii. What makes this fake moon uniqueThe full moon rises behind the Eiffel Tower in Paris, France.
