The claim

“"NASA has issued a warning that a giant asteroid will hit Earth in 2026."”

NASA has not issued any warning of a “giant asteroid” impacting Earth in 2026; known near-Earth objects tracked by NASA currently show no credible 2026 impact threat.

This claim commonly circulates via sensational social posts that conflate routine near-Earth-object tracking with an “impact warning.” NASA’s Center for Near Earth Object Studies (CNEOS) and the Jet Propulsion Laboratory’s NEO pages publicly track close approaches and publish risk assessments; an actual credible impact threat would appear in those risk tables and be widely reported with specific object identifiers and probabilities. As of NASA’s publicly available NEO risk information, there is no listed “giant asteroid” with a confirmed 2026 Earth-impact trajectory. If a post does not name the asteroid (designation), provide an official NASA link, or cites vague “NASA warned” language, it is typically misinformation built on unrelated close-approach news.
