Zenetae allegedly is the name of a binary star system in the constellation of Andromeda that is the home of the aliens Alex Collier is in contact with.
The only information on Zenetae comes from Alex Collier. He mentions it is a binary system in the constellation of Andromeda. At present, only one binary system has been identified in Andromeda, and that is Upsilon Andromeda, which is approximately 44 Light Years away. Its main star is called Titawin, and its companion star is a red dwarf.
The Andromedans Collier described are of the humanoid phenotype, but with different features. They have a light blue skin that becomes paler as they age. They are hairless. What stands out, are their eyes: "Their pupils change color. They tend to slant a little on the inside and outside, but for all intents and purposes they are round. It's like a cross of the 'round-eye' and the oriental eye. (...) I was so focused not only on their eyes changing color, but with the flashes of color on their forehead between their eyes."
These Andromedans are tall: females are between 7 to 8 feet (2.1 to 2.4 meter) tall, whereas most males are between 7 and 10 feet (2.1 to 3 meter) tall. Some males can grow to be 12 feet (3.6 m) tall.
Their lifetimes can span a couple of millennia. (Collier says their average age is around 2 000 years).
They are a telepathic race. Collier says these Andromedans are 45000 years* ahead of us technologically and are very spiritually advanced race as well.
[*Note: unclear whether 4500 or 45000 years, as the text says 4,5000].
