What Is Our Solar System Called?

Our solar system only has one name: “The Solar System.” The Latin word for sun, “Solis,” is where this name is derived. It consists of the star at the center of our solar system and everything else orbiting around it. Our sun is the powerhouse of our solar system.

What makes up the Solar System?

Our solar system is made up of eight planets that orbit around the sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. In addition to these eight planets, there are many asteroids and moons orbiting around them. The sun is the largest object in our solar system by far, and it is also the source of light and heat that powers all of the celestial objects in our solar system.

The planets of the solar system

Based on the definition by NASA, planets are celestial bodies that should meet specific criteria:

  1. Must orbit a star, in this case, the Sun.
  2. Has sufficient mass and enough gravity to form a sphere-like shape.
  3. Has a strong gravitational pull that can push away similar and smaller shaped objects around its orbit.
  4. Is not a satellite of other planets.

The inner planets consist of Mercury, Venus, Earth, and Mars. These planets are also called terrestrial planets since they have rocky or solid surfaces, and out of all the inner planets, Earth is the only known habitable planet fit for life.

The outer planets, or gas giants, consist of Jupiter, Saturn, Uranus, and Neptune. These planets are much larger than the inner planets since they are made almost entirely of gases like hydrogen and helium. The outer planets also have moons that orbit around them just as the inner planets do.

Dwarf planets are a relatively new category of objects that orbit the sun, and they include Pluto and many other small planets. Since they don’t meet the third criterion of being a planet, they have been given their own category.

Satellites of the solar system

Satellites are celestial bodies that orbit around a star or a planet. So, technically, planets are satellites of the Sun. However, what sets them apart is that they are typically larger in size than a moon. Our solar system has many moons that orbit around the planets, and some of these bodies are among the largest known objects to exist in our solar system

Our solar system is an incredibly fascinating and dynamic place. It is constantly in motion as planets orbit around the sun and moons orbit their planets. It is also constantly changing, with new discoveries being made all the time about the planets, asteroids, and other bodies that make up this incredible system.

The Solar system in the Milky Way Galaxy

Our solar system is located in the Milky Way Galaxy, and comparing the solar system to the Milky Way is like comparing a grain of sand to the size of an entire beach. The Milky Way Galaxy is one of many galaxies in our universe, and it contains somewhere around 100 billion stars, including our sun. It is an awe-inspiring sight to look up at the night sky and see all of those stars shining down on us.


Our solar system has no other name than simply “the solar system.” It is a dynamic and fascinating place that contains many different objects and celestial bodies, all of which orbit around our sun. Whether you look up at the night sky to see thousands of stars shining down on us or take a closer look with a telescope to learn more about our planets, moons, and other objects, there is always something new and exciting to explore in the solar system.‚Äč
