The orbital radius and the orbital speed is directly proportional. When the radius is increased, the orbital speed will also increase but it has to add energy to the system to increase the orbital radius.
The four terrestrial planets are known as Mercury, Venus, Earth and Mars, they are all rocky planets composed primarily of silicate rocks and/or metals.
