7. Orbital elements - Wikipedia, the free encyclopedia
- en2.wikipedia.org
- Orbital elements.
- The elements of an orbit are the parameters needed to specify that orbit uniquely, given a model of two ideal masses obeying the Newtonian laws of motion and the inverse-square law of gravitational attraction. Because there are multiple ways of defining a motion, depending on which set of variable you choose to measure, there are several different ways of defining sets of orbital elements, each of which will define the same orbit.
- There are seven degrees of freedom in this model (time, position in 3-space at that time, velocity in 3-space at that time) so all sets of orbital elements have seven parameters. ...
- 1 Keplerian elements 2 Two line elements 3 See also 4 External links .
- Keplerian elements.
- The traditionally used set of orbital elements is called the set of Keplerian elements, after Johannes Kepler and his Kepler's laws. The Keplerian elements are:.
- Keplerian elements can be obtained from orbital state vectors using VEC2TLE software or by some direct direct computations.
- Other orbital parameters, such as the semi-major axis, can then be calculated from the Keplerian elements. ... The elements can be seen as defining the orbit by degrees:.
- Because the simple Newtonian model of orbital motion of idealized points in free space is not exact, the orbital elements of real objects tend to change over time. ... For the planets and moons it is more usual simply to add a time term to the elements.
- Two line elements.
- Keplerian elements parameters can be encoded as text in a number of formats. The most common of them is the NASA/NORAD "two-line elements" (TLE) format, originally designed for use with 80-column punched cards, but still in use because it is the most common format, and works as well as any other.
