Add a definition From the perspective of the perturbation theory used in celestial mechanics to compute the evolution of the orbit, thesemi-majoraxisis an adiabatic invariant. From Wikipedia ![]() For the special case of a circle, thesemi-majoraxisis the radius. From Wikipedia ![]() The expressions below give the auxiliary latitudes in terms of the geodetic latitude, thesemi-majoraxis, "a", and the eccentricity, "e". From Wikipedia ![]() This means that it is slightly flattened, its semi-minor axis being 70% of itssemi-majoraxis. From Wikipedia ![]() This was possible due to large size of the planet and its smallsemi-majoraxis. From Wikipedia ![]() This form of the equation is particularly useful when dealing with parabolic trajectories, for which thesemi-majoraxisis infinite. From Wikipedia ![]() Thesemi-majoraxisis known if the mean motion and the gravitational mass are known. From Wikipedia ![]() The two stars orbit each other with asemi-majoraxisof 1.437 arcseconds and a period of 116.24 years. From Wikipedia ![]() For any ellipse, let "a" be the length of itssemi-majoraxisand "b" be the length of its semi-minor axis. From Wikipedia ![]() As the eccentricity of the orbit evolves, thesemi-majoraxisof the orbital ellipse remains unchanged. From Wikipedia ![]() Thesemi-majoraxisis one half of the major axis, and thus runs from the centre, through a focus, and to the perimeter. From Wikipedia ![]() To calculate a dynamical parallax, the angularsemi-majoraxisof the orbit of the stars around each other is observed, together with their apparent brightness. From Wikipedia ![]() One is invariably the equatorial radius, which is thesemi-majoraxis, "a". From Wikipedia ![]() This central pair has asemi-majoraxisof around 867 km and a period of about 1.9 days. From Wikipedia ![]() The two stars orbit around their common centre of mass once every 78.7 years and the secondary has asemi-majoraxisof 0.165 arcseconds. From Wikipedia ![]() We obtain the orbital period of each planet, thesemi-majoraxisof its orbit and the orbital eccentricity. From theCambridge English Corpus Itssemi-majoraxisis 1.8km mi and its orbital period is 16.4 hours. From Wikipedia ![]() If the objectsemi-majoraxisis outside these narrow ranges, the orbit becomes chaotic, with widely changing orbital elements. From Wikipedia ![]() These examples are from corpora and from sources on the web.
