A second moon for Earth? NASA’s quasi-moon begins its 50-year orbital journey around our planet until 2038

Earth has a new cosmic companion, a 19-meter asteroid named 2025 PN7, discovered in August 2025. This 'quasi-moon' will orbit near Earth for about 50 years, until 2083. Scientists are excited as it offers a unique opportunity to study solar system dynamics and potentially ancient materials, posing no threat to our planet.
