Answer: Gas giants have a larger orbital radii.
Explanation:
There are two type of planets present in our solar system:
1. Terrestrial planets: These planets are known as rocky planets or inner planets in our solar system. They are Mercury, Venus, earth and Mars. These planets lie close to earth and hence have smaller orbital radii.
2. Gas Giants: These planets are large planets which compose mostly gases. They are known as outer planets in our solar system. They are Jupiter, Saturn, Uranus and Neptune. These planets lie away from the sun and hence, have larger orbital radii.
Therefore, the gas giants have a larger orbital radii.
