Semi-amplitude [edit] System components Upsilon Andromedae A is a yellow-white dwarf of spectral type F8V, similar to our Sun but rather younger, more massive and luminous. The system consists of an F-type main-sequence star (designated υ Andromedae A, officially named Titawin /tɪtəˈwiːn/) and a smaller red dwarf. The dimmer star Upsilon Andromedae B is only visible with a telescope.

Upsilon Andromedae B is a red dwarf of spectral type M4.5V located approximately 750 AU from the primary star. (~116.4 h) [4], A limitation of the radial velocity method used to detect Upsilon Andromedae b is that only a lower limit on the mass can be found. [9], The planet (with 51 Pegasi b) was deemed a candidate for direct imaging by Planetpol. Observations suggest that there is a "hot spot" on the star around 169° away from the sub-planetary point.

In the case of Upsilon Andromedae b, this lower limit is 68.7% of the mass of Jupiter, though depending on the inclination of the orbit, the true mass may be much greater. Discovery method Upsilon Andromedae b is the innermost known planet in its planetary system. [3], Like 51 Pegasi b, the first extrasolar planet discovered around a normal star, Upsilon Andromedae b orbits very close to its star, closer than Mercury does to our Sun.

Sudarsky had, on the assumption that the planet is similar to Jupiter in composition and that its environment is close to chemical equilibrium, predicted Upsilon Andromedae b to have reflective clouds of silicates and iron in its upper atmosphere. The recent announcement of the possible existence of another solar system, with planetary bodies (b, c, d) orbiting a star, similar to our own solar system, has been theoretically postulated for the Upsilon Andromedae system.The U Andromedae system lies at a distance of around ~43.93 light years from our solar system.
