An asteroid that has an orbital period of 3 years will have an orbital with a semi-major axis of about years.

An asteroid that has an orbital period of 3 years will have an orbital with a semi-major axis of about  2 years.

Explanation:

Given;

orbital period of 3 years, P = 3 years

To calculate the years of an orbital with a semi-major axis, we apply Kepler's third law.

Kepler's third law;

P² = a³

where;

P is the orbital period

a is the orbital semi-major axis

(3)² = a³

9 = a³

a =

Therefore, An asteroid that has an orbital period of 3 years will have an orbital with a semi-major axis of about  2 years.
