克卜勒轨道 Kepler orbit

（重定向自Keplerian orbit）
不同型式的克卜勒轨道和离心率图。蓝色是双曲线轨道（e > 1），绿色是抛物线轨道（e = 1），红色是椭圆轨道（e < 1），灰色是圆轨道（e = 0）。
The mechanisms of Newton's law of universal gravitation; a point mass m1 attracts another point mass m2 by a force F2 which is proportional to the product of the two masses and inversely proportional to the square of the distance (r) between them. Regardless of masses or distance, the magnitudes of |F1| and |F2| will always be equal. G is the gravitational constant.
Keplerian orbital elements.
An elliptic Kepler orbit with an eccentricity of 0.7, a parabolic Kepler orbit and a hyperbolic Kepler orbit with an eccentricity of 1.3. The distance to the focal point is a function of the polar angle relative to the horizontal line as given by the equation (13)
与数学更进一步与密切的发展，请参见二体问题、引力二体问题、和克卜勒问题。

克卜勒轨道是天体力学描述在三维空间的椭圆、抛物线或双曲线轨道上运动的物体在二维轨道平面上的轨道运动（克卜勒轨道也可以是直线）。它只考虑两个点状物体之间的引力作用，而忽略与其它物体之间引力交互作用的摄动、大气拖曳、太阳辐射压、非球面的中心物体等等。因此说它是二体问题，也就是所谓的克卜勒问题的一个特殊解。在经典力学中，它也不会考虑到广义相对论的影响。克卜勒轨道可以用六个轨道要素的参数呈现出各种不同型式的轨道。

在大多数的应用中，在中心的质量被假设为整个系统的质量中心所在。经过分析，两个质量近似的物体可以用克卜勒轨道叙述它们绕着共同的质量中心，它们的引力中心（质心）。

A diagram of the various forms of the Kepler Orbit and their eccentricities. Blue is a hyperbolic trajectory (e > 1). Green is a parabolic trajectory (e = 1). Red is an elliptical orbit (0 < e < 1). Grey is a circular orbit (e = 0).

In celestial mechanics, a Kepler orbit (or Keplerian orbit) describes the motion of an orbiting body as an ellipse, parabola, or hyperbola, which forms a two-dimensional orbital plane in three-dimensional space. (A Kepler orbit can also form a straight line.) It considers only the point-like gravitational attraction of two bodies, neglecting perturbations due to gravitational interactions with other objects, atmospheric drag, solar radiation pressure, a non-spherical central body, and so on. It is thus said to be a solution of a special case of the two-body problem, known as the Kepler problem. As a theory in classical mechanics, it also does not take into account the effects of general relativity. Keplerian orbits can be parametrized into six orbital elements in various ways.
