Overview
- NASA and astronomers say 2025 PN7 poses no known risk and measures an estimated 18 to 36 meters across.
- The object’s heliocentric orbit closely matches Earth’s, creating a quasi-satellite resonance that makes it appear to accompany the planet.
- Even at its nearest, 2025 PN7 remains millions of kilometers away, far beyond the Moon’s average distance of about 384,400 kilometers.
- Modeling suggests the asteroid has been near Earth for decades and may remain in this configuration until roughly 2083 before drifting away.
- The clarification follows media and social posts calling it a "second moon," a label scientists reject as inaccurate.
