Orbital inclination refers to the angle at which a satellite or a planet's orbit is angled in relation to the equator of its parent body. It determines how closely the orbit is aligned with the equator or how tilted it is. Full definition
The brown dwarf has a near edge - on orbital inclination of around 97.3 +0.4 / -0.3 degrees from the perspective of an observer on Earth, a period of around 73.3 years (Liu et al, 2002; in pdf; and Crepp et al, 2012). (solstation.com)
Assuming this hypothetical planet had a low orbital inclination with respect to the mutual orbit of Alpha Centauri A and B, then the secondary star would start beside the primary at «stellar» conjunction. (en.wikipedia.org)
Photometry collected in 1982 appeared to support a binary companion with an orbital period of 10 days, but total radial velocity might be «quite small» because of a small orbital inclination (Fisher et al, 1983). (solstation.com)
