Oort Object Stream 2001 (OOS-2001)
A long-duration stream of rocky, icy, and metallic bodies originating in the Oort Cloud has entered the inner Solar System. The stream, designated Oort Object Stream 2001 (OOS-2001), was first identified following an atmospheric event over Kerala in July 2001. Several objects associated with OOS-2001 have since passed near Earth or entered the atmosphere, while additional objects remain on trajectories toward the inner Solar System. Confirmed and projected events associated with OOS-2001 are summarized below.

| Note: This table presents selected confirmed and projected OOS-2001 objects and events considered relevant to Earth or near-Earth space. Small or low-significance objects and atmospheric events may be omitted, including those that produced no measurable or consequential effects. Objects associated with OOS-2001 that are not considered relevant to Earth, including those projected to remain in other regions of the Solar System, are not included. | ||||||
