How Do Planets Get Their Names? We Asked a NASA Expert

How do planets get their names? With the exception of Earth, the planets in our solar system were named after Greek or Roman gods. Today, the job of naming things in space falls to the International Astronomical Union (IAU), the internationally recognized authority for naming celestial bodies and their surface features. NASA scientist Dr. Henry Throop explains more.

Welcome, space enthusiasts, to a mind-boggling journey through the celestial mysteries of our universe! Ever wondered how those magnificent planets in our night sky got their spellbinding names? Brace yourselves, because today, we're unveiling the captivating cosmic origins of these planetary titles that have enchanted humanity for millennia.

Imagine, if you will, a time thousands of years ago, when our ancestors gazed upon the heavens in awe. They beheld five radiant wanderers, visible to the naked eye, dancing in the firmament: Mercury, Venus, Mars, Jupiter, and Saturn. These cosmic luminaries were known to civilizations across the globe, each culture bestowing upon them unique names.

But hold on! The names we use today, like Mercury and Venus, trace their lineage to the ancient Romans. Why, you ask? Well, those early European astronomers chronicled their celestial discoveries in Latin, the language of the mighty Roman Empire. Thus, we inherited these majestic monikers from the Roman gods themselves – Mercury, Venus, Mars, Jupiter, and Saturn.

Now, my cosmic comrades, as we venture deeper into the cosmic abyss, we encounter three more celestial wonders: Uranus, Neptune, and the enigmatic Pluto. These names, my friends, carry the echoes of Greek and Roman mythology. Surprisingly, the Greeks and Romans never laid eyes on these distant worlds. But the explorers who unveiled them wanted to honor the age-old myths of their predecessors, weaving these newcomers into the tapestry of ancient cosmic lore.

Ah, but here's where the plot thickens! These outer celestial gems are vastly different from their inner brethren. They're elusive, faint, and languid in their celestial ballet. You can't simply glance at them with the naked eye. No, you need the aid of a telescope, a marvelous invention that unveiled these hidden wonders to the world.

Fast forward to our modern age. Telescopes have grown more colossal, astronomers more astute. We've uncovered cosmic gems, minuscule yet mesmerizing – objects just a few meters in size, barely larger than a human. We've stumbled upon a bounty of Kuiper Belt objects, akin to Pluto, albeit a tad smaller and farther away. While some still argue their planetary status, the International Astronomical Union, the guardians of cosmic nomenclature, often dubs them "dwarf planets."

The grand cosmic debate, my fellow explorers, centers on Pluto. Is it a planet, or is it not? The answer hinges on a delicate line drawn by size. It's a cosmic conundrum that has ignited passionate discussions among astronomers and space enthusiasts alike.

But let's not forget, fellow earthlings, there's more to name in our cosmic backyard. Moons, asteroids, comets, rings, Kuiper Belt objects, craters – a vast celestial canvas awaiting our earthly quill. For you see, as humans, we are driven to name these celestial wonders, to forge a connection with the boundless universe enveloping us.

So, dear viewers, as we set our sights on the stars and continue to unveil the mysteries of the cosmos, remember this: Thousands of years from now, humanity will still be giving names to planets and exploring the infinite wonders that lie beyond.

This, my friends, is the timeless journey of discovery, where the universe reveals its secrets one name at a time. Thank you for joining us on this epic cosmic odyssey!
