Order of the Eight Planets in the Solar System

Introduction

The solar system is made up of eight major planets that revolve around the sun. These planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The order in which they are arranged is determined by their distance from the sun. This article will discuss the order of the eight planets in the solar system.

Inner Planets

The four inner planets are Mercury, Venus, Earth, and Mars. They are also known as the terrestrial planets because they are similar to Earth in composition. These planets are the closest to the sun and are relatively smaller in size compared to the outer planets. Mercury is the closest planet to the sun and is followed by Venus, Earth, and Mars. The distance between each of these planets varies, but they are all relatively close to each other.

Outer Planets

The outer planets are Jupiter, Saturn, Uranus, and Neptune. They are also known as the gas giants because they are composed mainly of hydrogen and helium gases. These planets are much larger in size compared to the inner planets and are much further away from the sun. Jupiter is the largest planet in the solar system and is followed by Saturn, Uranus, and Neptune. The distance between each of these planets is much greater than the distance between the inner planets.

Kuiper Belt Objects

Beyond Neptune lies the Kuiper Belt, which is a region of space that contains many small icy objects. These objects are considered to be dwarf planets and include Pluto, Haumea, Makemake, and Eris. While Pluto was once considered to be the ninth planet in the solar system, it was reclassified as a dwarf planet in 2006. In conclusion, the eight planets in the solar system are arranged in order based on their distance from the sun. The inner planets are Mercury, Venus, Earth, and Mars, while the outer planets are Jupiter, Saturn, Uranus, and Neptune. Beyond Neptune lies the Kuiper Belt, which contains many small icy objects including dwarf planets. Understanding the order of the planets in the solar system is important in understanding the dynamics of our solar system.
