Summary

Story summary

A hidden asteroid nearing disintegration sheds dust and fragments that form a new meteor stream.
Its extreme orbit close to the sun heats its surface, causing cracks.
The discovery, published in March 2026 in The Astrophysical Journal, relies on 235,000 meteor observations.
Researchers linked 282 meteors to this stream, suggesting thermally driven breakdown adds to near-Earth debris.
NASA's NEO Surveyor, launching in 2027, aims to improve detection of such asteroids.
