According to Kepler's third law, a planet's orbital period (time to complete one full orbit) is directly related to the planet's average

Question

BlackTom AI · Accepted Answer

The question asks about Kepler's third law and what the orbital period of a planet is directly related to.
Option 1: diameter — Kepler's law does not relate the orbital period to a planet's size or diameter. The period depends on the orbit, not how wide the planet is.
Option 2: mass density — A planet's density does not determine how long it takes to complete an orbit around the Sun. Mass density can influence other dynamics, but not the simple P–a relationship in Kepler's formulation.
Option 3: age (since its formation) — The age of a planet has no direct bearing on the time it takes to orbit the Sun. Orbits are governed by orbital geometry and gravity, not formation age.
Option 4: distance from the Sun — According to Kepler's third law, the square of the orbital period (P^2) is proportional to the cube of the semi-major axis (a^3), which is essentially the planet's average distance from the Sun. This is the directly related quantity.
Option 5: period of rotation — This is the rotation of the planet around its own axis and is unrelated to the orbital period around the Sun; the two periods can be different and are governed by different physical processes.
In summary, among the options, the orbital period is directly tied to the planet’s average distance from the Sun (the semi-major axis), not to its size, density, age, or rotation period.
