Explicación
## Step 1The shape of a planet's orbit is determined by Kepler's laws of planetary motion. Kepler's first law states that the orbit of every planet is an ellipse with the Sun at one of the two foci.## Step 2An ellipse is an elongated circle, which means it is not perfectly circular but it is not irregular or parabolic either.## Step 3Therefore, the shape of a planet's orbit is not irregular, parabolic, or circular, but it is elliptical.
