The 4 smallest planets are also the 4 most inner planets: Mercury, Venus, Earth and Mars.
The 4 Inner planets (mostly rocky and solid):MercuryVenusEarthMarsThe 4 Outer planets (mostly dense gaseous atmospheres):JupiterSaturnUranusNeptuneNotes:Pluto, a dwarf planet, was an outer planet before it got reclassified, but resembles the inner planets.The inner and outer planets are separated by the asteroid belt.When dwarf planets are included, Ceres counts as an inner planet and all the other dwarf planets count as outer planets.
The inner planets in order are:MercuryVenusEarthMarsThe outer planets are Jupiter, Saturn (Gas giants), Uranus, and Neptune (Ice Giants)
Pluto used to be the smallest planet, but it's not a planet any more! That makes Mercury the smallest planet in our Solar System. The second smallest planet in the Solar System is now Mars, measuring 6792 km across.
The 4 inner planets (Mercury, Venus, Earth, and Mars) are solid planets made of rock. The 4 outer planets are gas giants.
The 4 smallest planets are also the 4 most inner planets: Mercury, Venus, Earth and Mars.
There are 4 inner planets: Mercury Venus Earth Mars There are 4 outer planets: Jupiter Saturn Uranus Neptune There are 8 in all.
the inner planets are closest to the sun and the outer planets are farthest from the sun { Answered by a grade 4 student}

As a general rule, an inner planet is a planet that comes before the asteroid bel.There are only 4 inner planets- Mercury, Venus, Earth, and Mars. The outer planets are after the asteroid belt and are Jupiter, Saturn, Uranus, and Neptune.

Earth is an inner planet. The inner planets are Mercury, Venus, Earth, and Mars. The outer planets are Jupiter, Saturn, Uranus, and Neptune. The inner planets are warmer and have solid, rocky cores. The outer planets are much cooler, bigger and are mostly, if not entirely, gas.
Those are the inner planets: Mercury, Venus, Earth, Mars.
From smallest (1) to largest (4) 1 Mercury. Diameter (at the equator) = 4880km or 0.3825 x Earths diameter 2 Mars. Diameter = 6794km or 0.5323 x Earths 3 Venus. Diameter = 12104km or 0.9488 x Earths 4 Earth. Diameter = 12756km
They are Mercury, Venuse, Earth and Mars: together these comprise the inner planet or terrestrial planets.
Mars is considered an INNER planet. It is the 4th of the 8 major planets in distance from the Sun, and is closer to the Sun than the Main Belt of asteroids. All 4 inner planets are terrestrial (smaller, rocky planets) while the outer planets are gas giants.*The inner planets are Mercury, Venus, Earth, and Mars*The outer planets are Jupiter, Saturn, Uranus, and Neptune.Planets past Neptune include all but one of the Dwarf planets, including Pluto, and a large number of smaller icy bodies in the Kuiper Belt.
Among the three its Mars, but in the solar system it is Mercury.
