Could this asteroid be a piece of the moon? A Chinese spacecraft is about to find outChina’s Tianwen 2 spacecraft begins investigating an asteroid that could be a fragment of the moon

China's Tianwen 2 spacecraft has begun investigating an asteroid near Earth to determine if it is a fragment of the Moon or an ordinary asteroid from the main belt.

The mission, launched in 2024 and active in July 2026, aims to collect samples that will help scientists understand the origin of lunar debris and the history of Earth-Moon interactions.

This research matters as it could reveal new insights into how planetary bodies exchange material and reshape our understanding of the solar system's evolution.

  • The asteroid Kamo'oalewa, which Tianwen 2 is studying, is approximately 40 meters wide and orbits Earth in a stable resonance.
  • Chinese space missions have previously confirmed the presence of water ice on the lunar surface using orbital instruments.
  • The Tianwen 2 mission includes a sample return capsule designed to land in Xinjiang after collecting asteroid material.
