Which of the following is not a terrestrial planet '?

The correct answer is Neptune. The first four planets are called Terrestrial, meaning earth-like planets like Mercury, Venus, Earth, and Mars.

What are 5 facts about terrestrial planets?

The surfaces of terrestrial planets have mountains, craters, canyons, and volcanoes. About 75% of Earth's surface is covered in water. Both Mars and Earth have permanent polar ice caps. None of the terrestrial planets in our solar system have ring systems.

Which is not a terrestrial planets characteristics?

Terrestrial planets have solid surfaces, while the Jovian planets do not. Jovian planets are also significantly larger in size and mass. For these reasons, the Jovian planets are often called "gas giants." The gas giant planets are Jupiter, Saturn, Uranus, and Neptune.
