  • 1963-047A = AC-2
  • 1966-084B = AC-7 (Surveyor 2), later rediscovered as 2020 SO
  • 1968-110B = AC-16 (OAO 2)
  • 1969-069B = AC-18 (ATS 5)
  • 1971-006B = AC-25 (Intelsat 402)
  • 1971-116B = AC-26 (Intelsat 403)
  • 1972-003B = AC-28 (Intelsat 404)
  • 1972-041B = AC-29 (Intelsat 405)
  • 1972-065B = AC-22 (OAO 3)
  • 1973-058B = AC-31 (Intelsat 407)
  • 1974-093B = AC-32 (Intelsat 408)
  • 1975-042B = AC-35 (Intelsat 401)
  • 1975-091B = AC-36 (Intelsat 4A-1)
  • 1976-010B = AC-37 (Intelsat 4A-2)
  • 1976-042B = AC-38 (Comstar 1A)
  • 1976-073B = AC-40 (Comstar 1B)
  • 1978-035B = AC-48 (Intelsat 4A-6)
  • 1978-068B = AC-41 (Comstar 1C)
  • 1981-018B = AC-42 (Comstar 1D)
  • 1985-055B = AC-64 (Intelsat 5A-11)
  • 1985-087B = AC-65 (Intelsat 5A-12)

    • NOTES:

    • The addon's Go-to Object button will take you to the Centaur booster of the Surveyor 2 lander, also known as 2020 SO
    • The names of these upper stages are permanently hidden to simulate their status as inactive, defunct objects floating in space, but they can still be searched on Celestia itself upon entering the word "Centaur" or "AC-"

    2020 SO, the spent Centaur-D stage of Surveyor 2, on its closest approach to Earth on 2020-Dec-1
