The angular distance of the orbital plane from the plane of the planet's equator, stated in degrees.
Industry:Aerospace
The line marking the apparent junction of Earth and sky. For the technical definition, please follow this link to the U.S. Naval Observatory's Astronomical Applications.
Industry:Aerospace
The space within the boundary of the heliopause, containing the sun and solar system.
Industry:Aerospace
The boundary theorized to be roughly circular or teardrop-shaped, marking the edge of the sun's influence, perhaps 100 AU from the sun.
Industry:Aerospace
Einsteinian distortions of the space-time medium predicted by general relativity theory (not yet directly detected as of March 2010). (Not to be confused with gravity waves.)
Industry:Aerospace
The mutual attraction of all masses in the universe. Newton's Law of Universal Gravitation holds that every two bodies attract each other with a force that is directly proportional to the product of their masses, and inversely proportional to the square of the distance between them. This relation is given by the formula at right, where F is the force of attraction between the two objects, given G the Universal Constant of Gravitation, masses m1 and m2, and d distance. Also stated as Fg = gmm/r2 where Fg is the force of gravitational attraction, M the larger of the two masses, m the smaller mass, and r the radius of separation of the centers of the masses. See also weight.
Industry:Aerospace
A geosynchronous equatorial circular orbit. Also called Clarke orbit.
Industry:Aerospace
Electromagnetic radiation in the neighborhood of 100 femtometers wavelength.
