Briefings

A 2026 article reports that Japan's Hayabusa2 spacecraft is expected to visit asteroid 1998 KY26 in 2031, where the asteroid's acceleration defies current explanations. The article suggests the body may be a 'dark comet' driven by escaping water gas, though this remains a theoretical hypothesis. The evidence is limited to a single 2026 article and does not provide data on the asteroid's composition, the specific mechanism of gas escape, or the spacecraft's trajectory. No further details on the scientific community's reaction or the asteroid's location are available.

Key points

• Japan's Hayabusa2 spacecraft is scheduled to visit asteroid 1998 KY26 in 2031.
• The asteroid's acceleration has not been fully explained by existing models.
