gravitasjonsparameteren
Gravitasjonsparameteren, also known as the standard gravitational parameter, is a fundamental concept in astrodynamics and celestial mechanics. It is a measure of the gravitational influence of a celestial body, such as a planet or a star. The parameter is denoted by the symbol μ (mu) and is defined as the product of the mass of the celestial body (M) and the gravitational constant (G), i.e., μ = GM. The value of μ is crucial for calculating the orbits of satellites and spacecraft around the celestial body.
The gravitasjonsparameteren is particularly important in the context of the two-body problem, where the motion of
The gravitasjonsparameteren is also used in the context of the n-body problem, where the gravitational interactions
In summary, the gravitasjonsparameteren is a fundamental concept in astrodynamics and celestial mechanics, used to quantify
