Korea's geostationary weather-communications satellite, the Cheollian , had to be deflected earlier this week to prevent it colliding with a Russian military communications satellite.
The Korea Aerospace Research Institute says the Raduga 1-7 came within three kilometers of the Cheollian's orbit at 128.2 degrees east longitude between Monday and Tuesday.
The institute quickly revised Cheollian's orbit using a satellite thrusterand is keeping a close watch on the satellite.
The Cheollian is currently 120 kilometers apart from the Russian satellite.
The Russian satellite's abrupt movement also caused two Japanese satellites to be deflected.
Seoul and Tokyo have jointly asked for an explanation from Russia, but Moscow has not responded yet.
