Semi-major axisEccentricityKS elementsPredicting the orbit of a satellite is a fundamental requirement in many areas of aerospace, such as mission planning, satellite geodesy, re-entry prediction, maneuver planning, collision avoidance, formation flying, etc. For near-Earth orbits, the forces due to...
the semimajor axis of the Hohmann transfer is one-half of the sum of the radii of the two circular orbits. Knowledge of the Hohmann transfer semimajor axis allows computation of the transfer time and the required velocities at each apse of the ellipse. Two velocity increments (Δv1and Δv2...
The formula for calculating a satellite's orbital distance from Earth is d = a(1 - e^2) / (1 + e cosθ), where d is the satellite's distance from Earth, a is the semimajor axis, e is the eccentricity, and θ is the true anomaly. Can you calculate the distance between a satel...
the eccentricity of the orbit e, the time of passage at some initial periastron To, and some corresponding angular position of the periastron ω0, and, finally, the projected semi-major axisx=a1sinic, where a1 is the semi-major axis of the orbit of the observable pulsar15 and i is the...
Even if the planet's eccentricity has alwaysbeen zero, we show that tidal decay of semi-major axis could have been largeenough that the planet formed on a wider orbit which received less insolation.Moreover, CoRoT-7 b could be tidally heated at a rate that dominates itsgeophysics and ...

The new semi major axis is calculated to be 𝑎′=6811 kma′=6811 km, while the eccentricity is 𝑒=0.017e=0.017. By having these elements to be used as inputs in the DRAMA–OSCAR tool, the orbital decay analysis can be performed. As illustrated in Figure 8, it results that the S...
In terms of its orbit, Earth has a very minor eccentricity (approx. 0.0167) and ranges in its distance from the Sun from 147,095,000 km (0.983 AU) at perihelion to 151,930,000 km (1.015 AU) at aphelion. This works out to an average distance (aka. semi-major axis) of 149,598,26...
I have investigated the time derivatives of orbital semimajor axis a, eccentricity e, and inclination i of a body orbiting in a gaseous disk. I have derived [Math Processing Error], [Math Processing Error], and [Math Processing Error] for e>0.9 and i<H/2a (Equations 14 to 16) and ...
