The Jovian planets are a more evolved type of planet. Since they are farther from the Sun, they are less affected by the Sun and undergo less change.
Terrestrial planets are small, rocky, and have solid surfaces, while jovian planets are large, gaseous, and lack solid surfaces. Jovian planets also have thick atmospheres composed mostly of hydrogen and helium, while terrestrial planets have thinner atmospheres with varying compositions.
The planets that are not classified as terrestrial are Jupiter, Saturn, Uranus and Neptune. If you count Pluto as a planet then it would be a part of that list as well. Mercury, Venus, Earth and Mars are the terrestrial planets. Jupiter, Saturn, Uranus and Neptune are the gas giants. Pluto is a dwarf planet.
The three qualifications for a planet are: 1. It orbits the parent star. 2. It has hydrostatic equilibrium (roughly spherical shape) caused by the gravitational forces. 3. It has cleared its path of orbital debris. (This one is hotly contested.)

no it is not. Mars is actually ranked 7th by size.
Earth is a major planet. It is the third planet from the Sun in our solar system and one of the four terrestrial planets.

Earth and Mars, along with Mercury and Venus, are rocky planets.
The first four planets are often lumped together into the category of "inner" or "terrestrial" planets:MercuryVenusEarthMarsThe last four are often lumped together into the category of "outer" or "gas giant" planets:JupiterSaturnUranusNeptuneAll of the dwarf planets are terrestrial. The only dwarf planet that can sometimes be called an "inner planet" is Ceres, which orbits between Mars and Jupiter.

In our own solar system, there are eight major planets, ten dwarf planets, two protoplanets, and thousands of minor planets (asteroids). There are also billions of planets outside our own system, but they shall not be named here (it would be impractical to try). Below is a list, in orbital order, of major objects in the solar system, as well as how many known major objects orbit them:Sol (sun) [18 planets, three asteroid belts, two protoplanets, one theoretical dwarf star]Mercury (terrestrial planet)Venus (terrestrial planet)Earth (terrestrial planet) [1 moon, Luna]Mars (terrestrial planet) [2 moons]Asteroid BeltCeres* (dwarf planet)Vesta* (protoplanet)Pallas* (protoplanet)Jupiter (gas giant) [66 moons]Saturn (gas giant) [62 moons]Uranus (ice giant) [27 moons]Neptune (ice giant) [13 moons]Kuiper Belt [asteroids, dwarf planets]Orcus+ (dwarf planet) [1 moon, Vanth]Pluto+ (dwarf planet) [1 planet, Charon, 3 moons]Charon+ (dwarf planet) [1 planet, Pluto, 3 moons]Haumea+ (dwarf planet) [2 moons]Quaoar+ (dwarf planet) [1 moon, Weywot]Makemake+ (dwarf planet)Eris (dwarf planet) [1 moon, Dysnomia]"Snow White" (2007 OR10) (dwarf planet)Sedna (dwarf planet)Oort Cloud [comets, asteroids]Nemesis# (red dwarf star, theoretical)*Orbits within Asteroid Belt+Orbits within Kuiper Belt#Theoretical, sort of like Bigfoot
When homosapians evolved.
Pluto was considered a major planet from 1930 to 2006.
The three qualifications for a planet are: 1. It orbits the parent star. 2. It has hydrostatic equilibrium (roughly spherical shape) caused by the gravitational forces. 3. It has cleared its path of orbital debris. (This one is hotly contested.)
The group of fish that gave rise to terrestrial vertebrates is known as lobe-finned fish. These fish had fleshy fins with bony supports that eventually evolved into limbs capable of supporting the animals on land. The transition from water to land occurred during the Devonian period, around 360 million years ago.
