💡 Grammar Points
Unexpected Gender
Even though 'planetas' ends in -as, the singular form ('planeta') is masculine, so you must use 'los' (the) and masculine adjectives with it, like 'los planetas grandes' (the big planets).
❌ Common Pitfalls
Gender Confusion
Mistake: "Las planetas son interesantes."
Correction: Los planetas son interesantes. (The planets are interesting.) The word is masculine, regardless of the -a ending.
⭐ Usage Tips
Easy Plural
To form the plural, you just add an 's' to the singular form 'planeta', resulting in 'planetas'. This is a very regular pluralization pattern.

Frequently Asked Questions
Does 'planetas' refer to all kinds of celestial bodies?
While it can be used broadly, 'planetas' specifically refers to the large, round bodies that orbit a star (like the Sun). It typically excludes stars, moons, or small asteroids.
Why is 'planeta' (singular) masculine if it ends in -a?
This is a common exception! Words ending in -ma, -pa, or -ta that come from Greek (like 'problema' or 'planeta') are often masculine in Spanish. Just remember to use 'el' and 'los' with them.
