18
Compared to the Jovian planets, terrestrial planets are
less dense and smaller
more dense and larger
less dense and larger
more dense and smaller
19
As planets orbit towards a perihelion distance, the velocity of the planet's orbit
increases
decreases
remains the same
20
As you increase the distance between two foci points, the shape of the ellipse
gets more circular
gets smaller
gets bigger
gets flatter and wider
