Suppose the Hubble Space Telescope discovers a series of planets with these characteristics moving around a star that resembles our Sun: spherical, solid surfaces; mean densities about 4 times that of water; radii about 4000 km; and low-density atmospheres. How would these planets be classified in comparison with our solar system?
A) terrestrial planets
B) Jovian planets
C) cometary nuclei
D) asteroids

These planets would be classified as terrestrial planets because they have solid surfaces, densities higher than water (similar to Earth, Mars, Venus, and Mercury), and relatively small radii, which are characteristics of terrestrial planets in our solar system.
