There is a bit of a misunderstanding in your question. Planets don't have "real names" in the sense that they have aliases. The names we use for planets are their actual names.

Here are the names of the planets in our solar system, along with their origins:

* Mercury: Named after the Roman messenger god, known for his speed, reflecting the planet's rapid orbit.

* Venus: Named after the Roman goddess of love and beauty, likely due to its brightness in the sky.

* Earth: The name comes from Old English and Germanic words meaning "ground" or "soil".

* Mars: Named after the Roman god of war, due to its reddish color, which was associated with blood and fire.

* Jupiter: Named after the Roman king of the gods, reflecting its size and dominance in the solar system.

* Saturn: Named after the Roman god of agriculture and time, due to its slow orbit.

* Uranus: Named after the Greek god of the sky, discovered in 1781 by William Herschel.

* Neptune: Named after the Roman god of the sea, reflecting its blue color, discovered in 1846.

So, these are the "real" names of the planets, and they are the only names they have!
