Timir

HD 148427, HIP 80687

As seen fron Earth, Timir is a faint orange star of seventh magnitude, and thus undetectable to the naked eye. It lies in the southwesterm parts of Ophiuchus, near that constellation's border with Scorpius, a little over a degree westward of the globular cluster M107. Timir lies approximately 230 light years from the Sun.

Timir is an evolved star, late in its life cycle, which has expanded to form a giant or subgiant, reaching a diameter some three times greater than that of the Sun. It has a companion object in a close orbit, of uncertain nature. Originally thought to be a gas giant planet, later measurements of the mass of this orbiting object (which is at least thirty times that of Jupiter) imply that it is either a brown dwarf or a low-mass red dwarf star. Timir's companion is designated HD 148427 b, and named Tondra.

The name Timir was selected as the entry for Bangladesh in the NameExoWorlds project, and comes from a Bengali word for 'darkness' (referencing that fact that the star lies in the distant darkness of space). The name of its companion Tondra comes from a word meaning 'drowse', suggesting the idea that the companion object was 'sleeping' before its discovery in the year 2009.
