Sentences with phrase «orbital inclination»
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).

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.
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).
However, the space station will re-enter somewhere between the latitudes of 43 degrees north and 43 degrees south, based on its current orbital inclination.
Even if some theory could explain the Moon's high orbital inclination and angular momentum, other problems remain.
About 70 % of the planet candidates in the CoRoT IRa01 field are best fit with an impact parameter of b > 0.85, while less than 15 % are expected in this range considering random orbital inclinations.
Of the 17 objects detected, most have orbital inclinations of less than 4 °, and all have inclinations of less than 20 °.
Although the initial display shows the system's actual orbital tilt (at an inclination of 79.2 °) from the visual perspective of an observer on Earth, the orbital inclination of any planet that may be discovered someday around either star would likely be different from those of the habitable zone orbits shown here.
According to Hummel et al (1994) in the new Sixth Catalog of Visual Orbits of Binary Stars, Stars Aa and Ab are separated by less than two - thirds (0.730) of an AU (68 million miles) and move with a circular orbit (e = 0.000) with a period of only 104.0 days and an orbital inclination of about 137.2 ° from the perspective of an observer on Earth.
According to the Astronomisches Rechen - Institut's Catalogue of Nearby Stars (ARICNS) notes on Star B, the BC companion binary pair has an observed separation of about 286 AUs (34.0» at a HIPPARCOS parallax of 0.11905 + / -0.00062») from primary pair Aab at an orbital inclination of 247 ° (1955) from the perspective of an observer on Earth.
According to Wulff Dieter Heintz (1975) in the new Sixth Catalog of Visual Orbits of Binary Stars, Stars C and D have an average separation of about 48.1 AUs (a = 3.72») and move in a circular orbit (e = 0) with a period of about 388 years and an orbital inclination of 65.0 ° from the perspective of Earth.
In particular, during the last 800,000 years, the dominant period of glacial — interglacial oscillation has been 100,000 years, which corresponds to changes in Earth's eccentricity and orbital inclination.
orbital system and of their component orbits (from the perspective of an observer on Earth) are as displayed, the orbital inclination of any planet that may be discovered someday in this star system would likely be different from those of the habitable zone orbits depicted here.
Richard A. Muller and Gordon J. MacDonald [4][5][6] and others have pointed out that those calculations are for a two - dimensional orbit of Earth but the three - dimensional orbit also has a 100,000 - year cycle of orbital inclination.
Although the initial display shows the system's actual orbital tilt (at an inclination of 136.5 °) from the visual perspective of an observer on Earth, the orbital inclination of any planet that may be discovered someday around Star A would likely be different from that of the habitable zone orbit depicted here.
This result, that systems with multiple transiting planets are less likely to include a transiting giant planet, suggests that close - in giant planets tend to disrupt the orbital inclinations of small planets in flat systems, or maybe even to prevent the formation of such systems in the first place.
