|Illustration of the Gliese 876 Planetary System|
The green disk represents the extent of the habitable zone (popularly referred to as the 'Goldilocks Zone'), of Gliese 876, in which, two planets, "876 b" and "876 d", partially occupy, in eccentric orbits, relative to each other. The zone is shown at an angle perpendicular to Gliese 876's axis of rotation.
The parent (host) star of this system, Gliese 876, is an 11th magnitude star. This means that, although the system is 87,000,000,000,000 (87 trillion) miles away - it can actually be seen in a medium-sized (6" aperture) telescope. Take a look!
