Did Christians kill Copernicus

No, Christians did not kill Copernicus. Nicolaus Copernicus, the astronomer who proposed the heliocentric model of the universe, died of natural causes in 1543. While his ideas faced opposition from some within the Church later, particularly during the Galileo controversy, Copernicus himself was not persecuted or killed for his theories. His work laid the foundation for modern astronomy and was published shortly before his death.
