HD 24040 b is a long-period exoplanet taking approximately 3700 days to orbit at 4.92 astronomical units in a circular orbit. It has minimum mass 4 times that of Jupiter. To have more accurate true mass, inclination must be known, yet the inclination is not known.[1][2] The refined mass of HD 24040b Msini = 4,10 + -0,12 mass of Jupiter, orbital parameters: the period of 3490 (9.56 years) + - 25 days, the semimajor axis of 4.637 + -0.067 AE. eccentricity of 0.047 + -0.020.
