The distance between Earth and Mars varies continuously due to their different orbital radii and angular velocities. Traditional analytical methods, based on the law of cosines, provide a simple estimation but fail to capture subtle orbital variations and smoothing effects. In this work, we propose a Hybrid Corrected Distance (HCD) model, expressed as:
d_HCD(t) = √[ R_E² + R_M² − 2 R_E R_M × (sin(Δθ/2)/(Δθ/2)) × (cos(Δθ/2))^(1/3) × (1 + 0.1 sin(Δθ/4)) ]
This formula introduces smooth trigonometric corrections to the classical geometric model, accounting for angular smoothing and small periodic variations. We present a detailed explanation, sample calculations, and comparison with the classical formula, demonstrating its utility for educational, theoretical, and analytical applications.

Excerpt from the Book
Motivation for the Hybrid Model
The classical model has two main limitations: Angular extremes: Sharp maxima and minima in distance occur due to the cosine term, exaggerating the real variation. Neglect of small periodic variations: Minor fluctuations in distance due to orbital eccentricity are ignored.
The HCD model addresses these by introducing three trigonometric correction factors: angular smoothing, fractional cosine power, and a harmonic correction.
