g Bellerophon (aka known as 51 Pegasi b): A protoytpe hot Jupiter, the tidally locked planet orbits star once every 4.230785 days. Its mass is about half that of Jupiter and 150 x Earth. The average temperature of the gas giant is about 1800 F. The planet probably has a greater radius than Jupiter despite a lower mass because the superheated atmosphere must be puffed up into a thick but tenuous layer surrounding it. Beneath this, the gases that make up the planet would be so hot that the planet would glow red. Clouds of silicates may exist in the atmosphere.

Three planets orbit the star:
g Mu Arae d: In a very hot but circular, inner orbit (e~0), the planet is estimated to have about 14 times the mass of Earth. Located at only 0.09 AUs from the star (less than one fourth of Mercury's orbital distance from Sol), the planet competes an orbit in 9.64 days and may have a surface temperature of 1,160° Fahrenheit (900° Kevin). Under the most likely planetary developmental scenario of an inner migration from around 3 AUs under the influence of outer giant planet "b" now at 1.5 AUs, this planet is likely to have an "essentially rocky core" with an atmosphere of 5-10 percent of its total mass. For a while, this planet was called "Mu Arae c" by those unaware of the now confirmed "c" candidate.
g Mu Arae e: At 52.19% of Jupiter's mass, this planet has an average orbital distance of about 0.921 AUs. It has a relatively circular orbit (e= 0.0666 ± 0.0122) which takes about 310.55 ± 0.83 days (85 percent of an Earth year) to complete.
g Mu Arae b: This Jupiter-class planet has at least 1.67 +/- 0.11 times Jupiter's mass. It moves around Mu Arae at an average distance of only 1.50 +/- 0.02 AUs (a semi-major axis around Mars's orbital distance) in an elliptical orbit (e= 0.31) that takes around 1.79 years (654.5 days) to complete
g Mu Arae c: A gas giant around 3.10 +/- 0.71 Jupiter-masses, the planet has a highly eccentric outer orbit (e~ 0.57 +/- 0.01) with a semi-major axis of 4.17 +/- 0.07AUs, which may take roughly 8.18 years (2986 +/- 30 days) to complete. It has a maximum separation of 0.43 arc-seconds (about 6.6 AUs) from Mu Arae
Habitable zone
g The orbit of an Earth-like planet (with liquid water) around Mu Arae may be centered around 1.3 AU - between the orbital distances of Earth and Mars in the Solar System - with an orbital period around 1.31 years (478 days). However, the eccentric orbit of planet b at an average orbital distance of around 1.5 AU would disrupt the orbit of an Earth-type planet around Mu Arae's water zone.

Known planets
Three planets orbit the star:
g Mu Arae d: In a very hot but circular, inner orbit (e~0), the planet is estimated to have about 14 times the mass of Earth. Located at only 0.09 AUs from the star (less than one fourth of Mercury's orbital distance from Sol), the planet competes an orbit in 9.64 days and may have a surface temperature of 1,160° Fahrenheit (900° Kevin). Under the most likely planetary developmental scenario of an inner migration from around 3 AUs under the influence of outer giant planet "b" now at 1.5 AUs, this planet is likely to have an "essentially rocky core" with an atmosphere of 5-10 percent of its total mass. For a while, this planet was called "Mu Arae c" by those unaware of the now confirmed "c" candidate.
g Mu Arae e: At 52.19% of Jupiter's mass, this planet has an average orbital distance of about 0.921 AUs. It has a relatively circular orbit (e= 0.0666 ± 0.0122) which takes about 310.55 ± 0.83 days (85 percent of an Earth year) to complete.
g Mu Arae b: This Jupiter-class planet has at least 1.67 +/- 0.11 times Jupiter's mass. It moves around Mu Arae at an average distance of only 1.50 +/- 0.02 AUs (a semi-major axis around Mars's orbital distance) in an elliptical orbit (e= 0.31) that takes around 1.79 years (654.5 days) to complete
g Mu Arae c: A gas giant around 3.10 +/- 0.71 Jupiter-masses, the planet has a highly eccentric outer orbit (e~ 0.57 +/- 0.01) with a semi-major axis of 4.17 +/- 0.07AUs, which may take roughly 8.18 years (2986 +/- 30 days) to complete. It has a maximum separation of 0.43 arc-seconds (about 6.6 AUs) from Mu Arae
Habitable zone
g The orbit of an Earth-like planet (with liquid water) around Mu Arae may be centered around 1.3 AU - between the orbital distances of Earth and Mars in the Solar System - with an orbital period around 1.31 years (478 days). However, the eccentric orbit of planet b at an average orbital distance of around 1.5 AU would disrupt the orbit of an Earth-type planet around Mu Arae's water zone.
