Planetary Information
| Other Names | 14 Herculis b |
| Common Name | None |
| Detection Team | |
| Detection Method | K0 V |
| Detection Date | July 6, 1998 |
| Mass (xJupiter) | 5.04 (exoplanets.org) |
| Diameter | ~142,000 kilometers (Sol Station) |
| Semi-Major Axis | 2.81 AU |
| Orbital Period | 4.6 years (exoplanets.org) |
| Orbital Eccentricity | 0.35 |
| Orbital Inclination | Unknown |
| Notes | Astrometric analysis suggests that the object may actually have 13 times the mass of Jupiter with an inclination of 155.3° from Earth's line of sight (Han et al, 2001, in pdf). Thus, the object could be an extremely dim brown dwarf companion of 14 Herculis. |
