The universe is vast, and the question always arises: How many planets are there in the solar system ? This question might seem simple to answer for some, but for others, it remains quite difficult. Currently, there are eight planets in the solar system, especially after Pluto was reclassified as a dwarf planet in 2006, thus ceasing to be part of the list previously taught in schools and other institutions.
How many planets are there in the Solar System?
The planets currently in the solar system are: Mercury, Venus, Earth , Mars, Jupiter, Saturn, Uranus, and Neptune . Pluto is not included in this list because, as we have already mentioned, it is no longer considered a "normal" planet but rather a "dwarf planet," which were explained in a previous article. If you wish to learn more about this topic, you can read about dwarf planets and their classification.

Relevant characteristics of the planets found in the solar system
In this sense, to better understand the universe and the galaxy in which we exist, it is important to know how many planets there are in the solar system and what characteristics define each of the planets mentioned at the beginning. Likewise, we will study each of the planets in the solar system, highlighting some of their most prominent features:
1. Mercury
It is the planet closest to the Sun and, likewise, the smallest in the entire solar system. In fact, its size is only slightly larger than that of the Moon. Being so close to the Sun, the side exposed to its rays is scorched, while the side in shadow cools considerably, reaching freezing point.
2. Venus
This planet is the most similar to Earth because it has a very similar size, density, and shape. Its unique characteristic is that it rotates in the opposite direction to the other planets. This makes it an interesting case, similar to other celestial bodies you can learn about in the characteristics of the planets in the solar system.
3 land
Earth is the third planet from the Sun in our solar system and our home. To date, it is the only known planet to harbor life and has a vast expanse of seas and oceans, which is why it is often called the "blue planet." To better understand its position and characteristics, I invite you to read about the orbits of the planets in the solar system.
4. Mars
Following this list of the planets in our solar system, we arrive at Mars, which occupies the fourth spot. Due to its reddish hue, it has been called the "red planet" and shares some characteristics with our own planet, as it has mountains, valleys, and frozen water. You can learn more about the composition of Mars in our article on the gas giants.
5 Jupiter
Jupiter is the largest planet in our solar system (estimated to be 1000 times larger than Earth) and is largely composed of gases such as helium and hydrogen. It has 16 moons orbiting it and a ring system. The sheer size of this planet has earned it a special place, as it is considered the largest planet in the solar system.
6 Saturn
This planet is famous for having a series of rings (more than 10.000) composed of rocks and ice. It is also a planet primarily made of gases. This phenomenon has been studied and is interesting for a better understanding of planetary rings.
7. Uranus
This planet has a very distinctive characteristic: it orbits on its side, which makes its seasons extremely long and varied. It is the third largest planet in our solar system. If you are an astronomy enthusiast, I invite you to read about fascinating facts about the solar system that will surely surprise you.
8. Neptune
It is the planet farthest from the sun , and for this reason, its temperature is very cold. To better understand its location and characteristics, you can consult the planets of the solar system in more detail.
The ninth planet of the Solar System
The ninth planet that may be part of our solar system was revealed by a team of astronomers from Caltech who found a large planet at the outer edges of the system, rotating unevenly with the other planets. Its current nickname is simply: Planet Nine.
It is estimated that this planet is ten times larger than Earth and twenty times farther from the Sun than Neptune , which we just showed was the planet with the greatest orbit. This group of scientists calculates that this New Planet could take about 10.000 to 20.000 years to complete one orbit around the Sun, given its distance. For more information about celestial bodies, you can read about how the solar system formed.
Konstantin Batygin and Mike Brown were the two astronomers who revealed this discovery through various mathematical calculations and simulations; however, it is true that even today it has not been detected in our universe . This is why we speak of a "supposed" planet, since it has not yet been observed, and the instruments used to observe the sky do not have the capacity to distinguish an object as distant as this planet.
Cases of the dwarf planets
Dwarf planets , as their name suggests, are smaller than most planets. Without going into specific figures, they fall somewhere between the so-called "normal" planets and asteroids. These dwarf planets are: Ceres, Pluto, Eris, Makemake, and Haumea. To learn more about this topic, you can visit the article on dwarf planets in the solar system.

Final conclusions of How Many Planets Are There In The Solar System
The Solar System is a planetary system located in the Milky Way galaxy. It consists of a single star, the Sun, a collection of smaller bodies, and of course, the planets.
In this sense, the Solar System consists of eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto was once considered a planet, but in 2006 it was reclassified as a dwarf planet.
