The Names of the Planets in Spanish

Did you know that the planets in our solar system are all named after the gods and goddesses of Roman mythology? Well almost all of the planets. Earth is the only planet not named after an ancient god. The ancient romans believed that gods controlled every aspect of life from the ocean to the sun. 

For example, Mercury, or Mercurio, the planet closest to the sun was named after the messenger god. Mars, or marte, the red planet was named after the god of war. These planets along with Jupiter, Saturn and Venus were all named by the ancient Romans thousands of years ago. These are the only planets that can be seen without a telescope.

Did you know that the days of the week in Spanish are also names after the planets? Learn more here.

The largest planet in our solar system is Jupiter. The hottest planet is Venus, which also happens to be the closest planet to Earth. Saturn’s rings are almost entirely made out of water particles. 

See if you can memorize the order of the planets according to their distance from the sun:

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Information about the planets in Spanish

Here is a fun fact: did you know there used to be nueve planetas (nine planets) in our sistema solar (solar system)? Pluto was once the smallest planet in our solar system but is no longer considered an actual planet due to its size. It is now considered a dwarf planet.

What’s a dwarf planet?

As the name suggests, the main difference between a regular planet and a dwarf planet is size. Pluto looks like a planet but did not meet the size requirement to be considered a full-fledged planet like Earth.

All of the planets in our solar system orbit around the sun. We are but a small part of a galaxy called the Milky Way. In Spanish, it’s known as la vía Láctea. It’s one of billions of galaxies that make up the vastness of the universe. The Milky Way can be observed by telescope or if you’re lucky enough to be somewhere far from light pollution even by the naked eye.

Here are some basic phrases to practice the names of the planets in Spanish:

 El sol brillará mañana. | The sun will shine tomorrow.

La luna esta llena. | The moon is full.

 La tierra es nuestro hogar. | Earth is our home.

Ways to teach children about the planets in Spanish

1. Through Space Picture Books

A great way to expose children to the planets and universe in Spanish is through reading picture books.

I have a list of 30 books about space in Spanish that you can browse through.

Spanish Books about Space for Kids

In our home, our favorite books is “El sol y los planetas.”

This is an interactive, pop-up book, perfect for older children, ages 7+.

It is jam-packed with information about the sun, moon, planet earth and surrounding planets. It has very nicely engineered pop-ups to show children the axis of the earth and the moon and how they revolve around each other.

I bought this book for my son when he was four years old and he absolutely loves it. I just paraphrase instead of reading all of the information in the book.
