Holberg 917G is a planet in the Omega system. It is located in or near Federation space. (TNG: "Conspiracy")
In 2239, this planet was purchased by a private concern, a gentleman named Mr. Brack. This was later revealed to be one of many aliases of the planet's only inhabitant, Flint the immortal, when the Federation starship USS Enterprise visited in 2269. The planet is home to a large quantity of natural ryetalyn. (TOS: "Requiem for Methuselah")
Background
Holberg 917G has two moons, although in the original matte painting only one is depicted. The planet could also be the moon of the other planet.
This depiction of Flint's home is a re-use of the matte painting executed for "The Cage".
Holberg 917G also appeared as a small note on a very large star chart graphic created for TNG: "Conspiracy". It was the image behind the chair in the room where Dexter Remmick was killed. It appears to be located within an outlined block, which may indicate that it was surrounded or was even a part of Federation territory at the time. It appears to be near Sol, Alpha Centauri, and Tau Ceti.
