What is terrestrial planet classification?
A terrestrial planet, telluric planet, or rocky planet, is a planet that is composed primarily of silicate rocks or metals. Within the Solar System, the terrestrial planets accepted by the IAU are the inner planets closest to the Sun, i.e. Mercury, Venus, Earth and Mars.
What are the three characteristics of terrestrial planets?
A terrestrial planet is one that meets these three planetary criteria and has a heavy metal core, a rocky mantle, and a solid surface. Surface conditions can vary greatly from planet to planet, but if it has a solid surface and a rocky inside, it is a terrestrial planet.
Which set of characteristics best describes terrestrial planets?
A terrestrial planet is one with a heavy metal core, a rocky mantle, and a solid surface. It also must meet the three planetary criteria as set forth by the IAU. Terrestrial planets share many common characteristics. This is because they all form from similar bits of metal and rock in inner protoplanetary disks.
