Here, ap is the length of the semimajor axis of the smaller body’s orbit relative to the larger body. Semimajor axis is a term used to define the radius of an elliptical orbit along the long dimension of the ellipse. (This will be discussed more later in this chapter.) Table 2.1 shows a list of the planets of our solar system and the value for the radius of the sphere of influence, rSOI.

Therefore, the larger the orbit size, the higher the differential temperature between the two points, as concluded in Bradley (7), Murphy and Lorenz (8), and Gomiciaga and Keogh (24). Gomiciaga and Keogh (24) found a similar trend via a CFD study, in which a general elliptic orbit was decomposed into a forward circular orbit and a backward circular orbit. Their results, well noted in the literature, revealed a nonlinear relationship, with a decreasing slope along the curve of versus orbit sizes (Gomiciaga and Keogh (24)).
