According to the doctrine of the Church of Jesus Christ of Latter-day Saints, the Terrestrial Kingdom is an eternal status in the afterlife to which some portion of humankind will be assigned following resurrection and the judgment day. The primary source of this doctrine is a vision recounted by Joseph Smith and Sidney Rigdon, at Hiram, Ohio, February 16, 1832, and recorded in Doctrine and Covenants, Section 76.
The Terrestrial Kingdom is the middle of three "degrees of glory," in which the highest or Celestial Kingdom is compared to the sun, the middle or Terrestrial Kingdom is compared to the moon, and the lowest or Telestial Kingdom is compared to the stars. Also, "in addition to the degrees of glory, there is a place of no glory, called perdition, reserved for those who commit the unpardonable sin." (Bible Dictionary: Degrees of Glory)
Persons who will attain the Terrestial Kingdom in the afterlife, according to the Church's teachings, include those who did not know about Jesus Christ during their life, but accepted Christianity after being taught about it in the afterlife.
