Proper Name | Saffar | Designations | Titawin b, Upsilon Andromedae A b, Upsilon Andromedae b | Classification | Gas giant | Orbital Period | 4 days, 15 hours | Mean Distance from Titawin | 8.9 million km 0.06 AU | Mass | 1.8 x Jupiter | Diameter | Not known | Mean Surface Temperature | 1,440 K (1,167°C) | Parent star | Titawin (Upsilon Andromedae), bright yellow dwarf in Andromeda | Other planets in this system | Majriti (Titawin d), gas giant Samh (Titawin c), gas giant Titawin e, hypothetical exoplanet | Notes | The innermost and least massive of three gas giant planets orbiting the star Titawin or Upsilon Andromedae. Titawin is in fact a binary star, with Saffar and its fellow planets orbiting the primary bright yellow dwarf (Upsilon Andromedae A) while its red dwarf companion follows a much more distant orbit of its own. |
The innermost of the three planetary companions of Titawin or Upsilon Andromedae. Its orbit
is astonishingly close to its parent star at just under 9 million kilometres, and it
completes this orbit so rapidly that its 'year' lasts less than five days.
