Unnamed stars

The following is a list of unnamed stars.

By planet

Kaelon II's sun

By system

By quadrant

Andromeda Galaxy

Makers' homeworld sun

This star, in the Andromeda Galaxy, was the primary for the Makers' homeworld. Sometime before 2268, this star went supernova, destroying its system. (TOS: "I, Mudd")

This sun was only mentioned in dialogue.

Unknown location

Abronian supernova star

Centuries prior to 3190, this star went supernova and destroyed the original Abronian homeworld. The only surviving Abronians were those who fled in a moon they had converted into a starship. The event was depicted in a mural within the ship. (DIS: "Choose to Live")

Lwaxana Troi star

Lwaxana Troi once had a star named after her by an astronomer from Rigel IV. (TNG: "Half a Life")

It is not specified exactly what portion of her name was used for the star.

Mad planet's sun

This star was shone over the mad planet. (TAS: "The Jihad")

Nyrian system star

According to the Nyrians (who proved to be less then honest), the Nyrian system contained a red giant star. (VOY: "Displaced")

O-type star

In 2256, the USS Discovery accidentally jumped into close proximity of this O-type star while trying to jump to Corvan II, and sustained minor damage during its escape. (DIS: "The Butcher's Knife Cares Not for the Lamb's Cry")

O-type stars usually appear as blue-white. The visual appearance of this star is more consistent with a G-type star or a red dwarf.

Unusual dead star

This dead star was encountered by the USS Enterprise while on course for Questar M-17 in 2269. It was discovered to be the source of mysterious radio emisions previously assumed to be from Questar M-17.

The object was unusual in that it had negative mass and intense hypergravity. A spectral analysis of the star revealed imploded matter, on which every reading was negative as well. Its surface appeared cratered. It also had some magnetic force. It was too far away from any G1 stars to be reached using sub-warp travel.

On stardate 5221.3, the USS Enterprise discovered the dead star while star charting. It was forced to go into orbit due to the object's hypergravity, after which the crew discovered an ancient vessel also in orbit.

A magnetic organism living inside the ancient ship returned to the Enterprise along with the away team and subsequently took control of that vessel. The Enterprise escaped, trapping the organism in Questar M-17's magnetic field. (TAS: "Beyond the Farthest Star")

The dead star might have been beyond the galaxy, as the Enterprise was on outward course beyond its fringe, and part of a spiral galaxy-like object can be seen in the background of one shot of it.
