SUMMARY
The eccentricity of Halley's Comet is calculated using the formula Rp = a(1 - e), where Rp is the periapsis distance and a is the semi-major axis. Given that the periapsis distance (Rp) is 0.6 AU, and the orbital period is 76 years, the semi-major axis can be derived from Kepler's Third Law. The eccentricity of Halley's Comet is established at 0.967, confirming its highly elliptical orbit.
