Is the newly discovered 2025 PN7 a natural quasi-moon or the Zond 1 mission? The answer lies in the possibility of alien civilizations visiting the solar system and installing monitors in the habitable zone to follow terrestrial life. These monitors could appear as small technological devices orbiting Earth as temporary secondary moons. The discovery of 2025 PN7 as a quasi-satellite has sparked debate. It's designated as such due to its orbital period close to 1 year and a non-zero eccentricity around the Sun. However, the question arises: is it a relic of an interplanetary mission from the 1960s? The author investigates this by comparing the trajectories of 1960s missions with 2025 PN7's path. The analysis reveals a potential match with the Zond 1 mission, a failed Russian mission to Venus. The object's closest approach to Earth is about 0.2 AU, which is less than the required 0.72 AU heliocentric distance. This discrepancy suggests that 2025 PN7 might be the Blok-L upper stage of the Zond 1 mission. The author further explores the possibility of 2025 PN7 being a technological artifact, drawing parallels to the identification of 2020 SO as the Centaur upper stage of the Surveyor 2 mission. The method used for identification involves spectroscopic analysis to determine surface composition and technological origin. The author concludes that 2025 PN7 could be a relic of the Zond 1 mission, but further verification is needed through spectroscopic analysis.
