HD 208487 is a 7th magnitude star in the constellation of Grus. Like our Sun, it is a yellow dwarf star. It has the same spectral type as our sun, G2 V. However, it is probably slightly less massive and more luminous, indicating that it is slightly older.

In 2004 a planet named HD 208487 b, found orbiting the star, was announced.
