The system consists of an F-type main-sequence star (designated υ Andromedae A, officially named Titawin in the Amazigh language /tɪtəˈwiːn/) and a smaller red dwarf.

In July 2014 the International Astronomical Union (IAU) launched NameExoWorlds, a process for giving proper names to certain exoplanets and their host stars.

[16] In December 2015, the IAU announced the winning names were Titawin for υ Andromedae A and Saffar, Samh and Majriti for three of its planets (b, c and d, respectively).

Consequently, the Chinese name for Upsilon Andromedae itself is 天大將軍六 (Tiān Dà Jiāng Jūn liù, English: the Sixth Star of Heaven's Great General).

This 13th-magnitude red dwarf is 55" from υ Andromedae A and is believed to be the only one of the companions physically associated, at the same distance and a projected separation of 750 AU.

It has been added to the WDS as component D.[22] Upsilon Andromedae A is a yellow-white dwarf of spectral type F8V,[4] similar to the Sun, but younger, more massive, and more luminous.

[24] Upsilon Andromedae A was ranked 21st in the list of top 100 target stars for NASA's cancelled Terrestrial Planet Finder mission.

[12] The red dwarf companion has a spectral type M4.5V and is located at a projected separation of 750 AU from the primary star.

[29] The discovery was made by Geoffrey Marcy and R. Paul Butler, both astronomers at San Francisco State University.

In 1999, astronomers at both San Francisco State University and the Harvard-Smithsonian Center for Astrophysics independently concluded that a three-planet model best fit the data.

General relativity is expected to have strong effects on planet b, because it orbits at a distance of just ~0.05 AU from the parent star.

The apsides of planet c and d, instead, oscillates with time;[27] the orbit of Upsilon Andromedae c thus returns to a nearly circular state every 9,000 years.

[39] Upsilon Andromedae does not appear to have a circumstellar dust disk similar to the Kuiper belt in the Solar System.

[43] This may be the result of perturbations from the companion star removing material from the outer regions of the Upsilon Andromedae A system.
