English to Spanish Translations of Planets and Space Words

Space is so vast that there's bound to be endless things within it that you might want to talk about in Spanish. If that sounds like something you'd be interested in, then this page should definitely help you out. By reading below, you will find three sections of space-related words - all translated from English to Spanish.

In the first section, you will find several general space words like asteroid, comet, galaxy, etc. After this, you will find some translations specific to the Sun and Moon. Finally, toward the bottom of the page you will find a full listing from English to Spanish of all the planets in our solar system (including Pluto, because I'm not ready to accept that it's not a planet anymore.)
