There are 4, all of which lie between the sun and the asteroid belt. These planets are (from lowest distance from the sun to the highest): Mercury, Venus, Earth and Mars.
There are four inner planets (Mercury, Venus, Earth and Mars) and four outer planets (Jupiter, Saturn, Uranus and Neptune). So there are an equal number of inner and outer planets.

The inner planets of our solar system have few or no moons. Mercury and Venus have none, Earth has one, and Mars has two.
The inner planets do not have many moons because what could become moons is usually trapped by one of the outer planets gravitational pull, lost in the asteroid belt, or crashes into the inner planets.
the inner planets are sometimes called Terrestrial Planets

The atmosphere protects the inner planets the same way as for meteors.
The inner planets of our solar system have few or no moons. Mercury and Venus have none, Earth has one, and Mars has two.
The inner planets are Mercury, Venus, Earth, and Mars. They are "inner" because the are the first 4 planets from the Sun.
After the inner planets you get the outer planets.
