Comet Tago–Sato–Kosaka, formally designated as C/1969 T1, is a non-periodic comet that became visible in the naked eye between late 1969 and early 1970.[3] It was the first comet ever observed by an artificial satellite.
Potential meteor shower
[edit]Due to the comet's very small minimum orbit intersection distance with Earth, both Zdenek Sekanina and Ichiro Hasegawa independently considered the possibility of a potential meteor shower originating from this comet, however no significant activity was observed.[3]
