Izar (or Epsilon Boötis III) is a Class M planet located in the Izar system of the Alpha Quadrant. In 2183, the United Federation of Planets established the Izar colony on the planet's surface, and the planet quickly became a member world, with a predominantly human population.
A heavily populated planet with many port facilities Izar is the fifth world orbiting Epsilon Bootis, a small orange star. (The Worlds of the Federation).
An early Earth colony Izar is now completely independent.
Izar's weather is infamous in the Federation for high winds, dust storms and tornadoes, which all occur on a regular basis. As a result most of Izar's settlements are located underground, since Izar is geologically inactive. (The Worlds of the Federation).
Starfleet's Kharicson Training Base is located here, on the continent of Pangaea, whereas New Seattle, the largest city and planetary capital is home to the Izar Institute of Meteorology. (The Worlds of the Federation).
In 2360, Ambassador Curzon Dax had a bottle of aperitif from Izar that he wanted to share with Admiral Nyota Uhura. (The Lost Era: "Catalyst of Sorrows")
By 2380, the population of Izar reached over 185 million people. (Star Trek: Star Charts).
Some of Izar's most famous citizens have been:
- Starfleet Fleet Captain Kelvar Garth, aka "Garth of Izar", one of Starfleet's best ever captains.
- Thomas Oromon, the 23rd President of the United Federation of Planets
- Christine Vale, Starfleet officer and security chief on the USS Enterprise (NCC-1701-E) and first officer of the USS Titan.
