Question

Halley’s comet has a perihelion distance of 0. 6 au and an orbital period of 76 years. What is the aphelion distance of halley’s comet from the sun?.

Answer 1

The Hailey's comet aphelion distance from the sun is 36 A. U.

The Hailey's comet perihelion distance = 0.6 amu

The Hailey's comet orbital period = 76 years

According to Kepler's law,

The time duration is T.

T = 76 years.

The semi-major axis is a.

The semi-major axis of Hailey's comet is,

$T ^{2} =a ^{3}$

$a = \sqrt[3]{(T) ^{2} }$

$a = \sqrt[3]{(76) ^{2} }$

= 18 A. U

The semi-major axis of Hailey's comet is 18 A. U.

The Hailey's comet aphelion distance from the sun is,

= 2 × a

= 2 × 18

= 36 A. U

Therefore, Hailey's comet aphelion distance from the sun is 36 Astronomical Units.
