| 释义 | orbit noun[ C or U ] uk /ˈɔː.bɪt/ us /ˈɔːr.bɪt/ orbitnoun[C or U] (CURVED PATH)the curved path through which objects in space move around a planet or star: （天体围绕行星或恒星运行的）轨道 in orbitThe satellite is now in a stable orbit.卫星目前在稳定的轨道上运行。 go into orbit aroundOnce in space, the spacecraft will go into orbit around Earth.一旦进入太空，航天器将进入环绕地球的轨道。 MARK GARLICK/SCIENCE PHOTO LIBRARY/GettyImages Astronomy albedo Andromeda Aquarius Aries asteroid galactic galaxy Gemini geostationary geosynchronous nova observatory orbital Orion penumbra substellar sunspot supergiant supermassive supermoon orbitnoun[C or U] (EYES)anatomy specialized one of two round areas in the skull(= the bones of the head) on either side of the nose that contain the eyes: A dental infection involving the upper teeth can easily spread itself into the orbit. Anatomically, the orbit consists of six facial bones. Synonym eye socket A CT scan of the head with special views of the orbit shows a normal brain and skull. The bones of the head create the bony orbits: symmetrical cavities that surround and protect the eye and associated structures. The roof of the orbit is formed by the orbital plate of the frontal bone anteriorly.

In opposition to this, chaos is effective for causing rapid desynchronization, because of its characteristic exponential divergence of nearby orbits. Dynamically we find most orbits to be stable over long time scales and typically this happens in a wider parameter area than in co-rotating systems. The bar will hence be able to relocate stars, and stars with low or high metallicity could be found far away from their original orbits. We only need that the return maps at periodic orbits are diagonal on the stable and unstable manifolds. In most cases, those planets follow orbits with significant eccentricity, leading to substantial seasonal temperature excursions. In most cases, those planets follow orbits with significant eccentricity, leading to substantial temperature excursions. Indeed, nebular drag and collisions would ensure that orbits with zero eccentricity were preferred. The steady-state solution of the equation of motion is then derived in cartesian coordinates and two groups of electron orbits are defined. Here, a planetary system consisting of one star and two identical-mass planets in circular but mutually inclined orbits is considered. Quasiperiodic orbits can look quite complicated, especially if there exist many incommensurable frequencies. The velocity of the planet orbiting at this distance satisfies the relation vn=w/n. The project mission was to locate intelligent signals coming from hypothetical planets orbiting the stars. A caustic is formed by the envelope of these orbits. Note that the orbits are almost per fectly laminar and there is no sign of filamentation. See all examples of orbit These examples are from corpora and from sources on the web.
