This is known as Keplers 2nd Law of Planetary Motion.
It states that line drawn between a planet and the sun sweeps out equal areas during equal time intervals.
the inner planets are sometimes called Terrestrial Planets
Actually Dwarf planets are planets which are very small in size and cannot be called planets but not as small to be called asteroids, so the name dwarf planets.
The theory that describes how all planets move around the Sun is called the heliocentric model. This model was proposed by Nicolaus Copernicus in the 16th century and states that the Sun is at the center of the solar system, with the planets orbiting around it in elliptical paths.
Objects that are smaller than planets are called "dwarf planets"; even smaller objects are called "asteroids".
Planets outside our solar system are called exoplanets. Thousands of exoplanets have been discovered orbiting other stars in the Milky Way galaxy. They come in a variety of sizes and compositions, and many are quite different from the planets in our own solar system.
The rules summarizing planetary movements are called Kepler's Laws of Planetary Motion. These laws were formulated by the astronomer Johannes Kepler in the early 17th century and describe the orbits of planets around the Sun.
The inner planets are small and rocky, the outer planets are much larger and have no solid surface, they are called the gas giants.
When a planet spins on its axis, it is called rotation. This rotation causes day and night cycles on the planet as different regions are exposed to sunlight and darkness.
They are sometimes called "major planets" to distinguish them from the "minor planets" (the asteroids) and "dwarf planets" like Pluto.

They are sometimes called minor planets (not mirror planets).They aren't planets really, but they are a bit like little planets orbiting the Sun.
The term "planet" comes from the Greek word "planētēs," which means "wanderer." Planets are called so because, unlike the fixed stars, they appear to move across the sky in relation to the background stars.
Jovian planets.
Terrestrial planets.
Because they are in the asteroid belt. The planets that are outside of the asteroid belt are called the outer planets.
It's called Tiny Planets, and they now have a website!
