The eccentricity of jupiter orbit is $\"\"$ .

The length of the major axis is $\"\"$ .

$\"\"$ .

Since the eccentricity is $\"\"$ , the conic is ellipse.

The polar equation of an ellipse with focus at the sun, semi major axis $\"\"$ , eccentricity $\"\"$ is $\"\"$ .

Substitute $\"\"$ and $\"\"$ .

$\"\"$

$\"\"$ .

The polar equation of the orbit is $\"\"$ .
