NameExoWorlds Brunei Darussalam

Currently there are a total of more than 4,000 confirmed planets that orbit stars outside the solar system known as exoplanets. Most of these exoplanets have no proper names. An initiative by the International Astronomical Union (IAU), NameExoWorlds offers the opportunity for all countries in the world including Brunei Darussalam to give a name to one exoplanet and its hosting star. Names will be chosen by public voting carried out in each country. The chosen names will be recognized by IAU as official names. A national committee for Brunei Darussalam will organize this campaign from August 2019 onwards.


  1. To provide opportunity for people of Brunei Darussalam to name exoplanet and its star.
  2. To raise public awareness on the existence of the planetary system outside our solar system.
  3. To promote astronomy especially Islamic astronomy (Falak Syarie) and space science in Brunei Darussalam.

Star Identification: HD 179949

Type: yellow-white, dwarf
Constellation: Sagittarius
Brightness: 6.25 magnitude
Surface Temperature: 6250 K (500 degrees hotter than the Sun)
Mass: 1.25 x sun
Distance from the Earth: 88 Light Years (8.3254 x 1014 km)
Spectral Class: F8 V

Description: HD 179949 is a sixth magnitude (6.25) class F8 dwarf star in Sagittarius. From a distance of 88 light years, it shines with a huminosity 1.8 times that of the Sun from a surface with a temperature of 6250 Kelvin, almost 500 degrees hotter tn the Sun. From these values, we infer a radius 1.16 times solar, a mass 1.25 solar, and that the star is very young. Like most planet-holding stars, it is metal-rich, with an iron content (relative to hydrogen) that is 65 percent greater than the Sun.
