What is the true extent of the semi-major axis for companion stars?
2016年7月14日 · The semi-major axis is measured as the average distance from the center of an elliptical orbit to one of the foci. Can the semi-major axis change over time? Yes, the semi-major axis can change over time due to gravitational interactions with other objects, such as planets or moons, in the system.
The Semi-Major Axis of Binary Stars - Physics Forums
2016年12月11日 · Can the semi-major axis change over time? Yes, the semi-major axis of binary stars can change over time due to various factors such as gravitational interactions with other nearby stars, tidal forces, and mass loss from one of the stars. These changes can cause the orbital period of the stars to change as well. How is the semi-major axis of ...
Calculating semi-major axis and minimum mass of an exoplanet
2016年6月6日 · The semi-major axis can be calculated using Kepler's third law, which states that the square of a planet's orbital period is proportional to the cube of its semi-major axis. By measuring the orbital period of the exoplanet and the mass of its parent star, scientists can calculate the semi-major axis.
Saturn's Semi-Major Axis: Exploring the 10-Year Orbit - Physics …
2010年6月6日 · In summary, Saturn's semi-major axis is the average distance between Saturn and the Sun, measuring the size of its orbit. It takes Saturn approximately 10.7 Earth years to complete one orbit, making it the sixth largest orbit among the eight planets in our solar system.
Semi-major axis from cartesian co-ordinates - Physics Forums
2009年11月23日 · The semi-major axis is half the length of the major axis, and the major axis is the longest diameter of an ellipse. Therefore, the semi-major axis is a crucial factor in determining the size and shape of an ellipse. How does the semi-major axis affect the orbital period of an object? The semi-major axis is directly related to the orbital period ...
Calculate Aphelion Distance & Velocity of Comet at Perihelion
2009年12月22日 · In summary, the comet has a perihelion distance of 0.6Au and a period of 341 years. To calculate its Aphelion distance, we can use the formula T^2 = a^3 and find a value of 48.8AU for the semi-major axis. To determine the velocity at perihelion, we can use the equation u = GM and substitute 1.5E11m for GM to convert to the MKS system.
