Get ready to tip the scales of your astronomical knowledge with these fascinating and entertaining fun facts about the Libra constellation!

1. Ancient Rome's Cosmic Scales

As fate would have it, ancient Rome's scales tipped in favor of cosmic justice – talk about balancing the act! With Italy as the ultimate balancer itself, old Rome and celestial Libra really knew how to measure up: It so happens that the Libra constellation was considered extremely influential in ancient Rome, with the Moon being in Libra during the city's founding. Italy was understood to belong to the Balance, and the symbol of Libra represented the equal hours of day and night. Rome's sovereignty over the world was even said to have been established under this constellation's sign. Today, though, Libra is a rather faint presence in the southern celestial hemisphere – proof that even the stars in the night sky aren't immune to humble pie!

2. Methuselah Star: Universe's Grandpa

Age before beauty? Try age amidst the cosmos! Methuselah Star, the universe's own grandpa, has seen it all and more: All jokes aside, HD 140283 – aka Methuselah Star – is around 14.5 billion years old, making it one of the oldest known stars in existence and even older than the estimated universe age at 13.77 billion years. Not only that, but this metal-poor subgiant with less than 1% of the Sun’s iron content is racing through our local stellar neighborhood and has an orbit from the ancient stars’ galactic halo.

4. Mars Skips Libra's Stellar Party

Is Mars playing hide-and-seek with Libra or what? It surely had its time to shine, but it chose Virgo instead: In April 2014, Mars reached opposition in Virgo, making it visible all night as a radiant red-orange beacon; however, it didn't pass through the Libra constellation, that's known for its striking star, Spica, sitting just a few degrees northwest of Mars.

Libra: The Zodiac's Inanimate Wallflower

5. Libra: The Zodiac's Inanimate Wallflower

In a celestial game of "one of these things is not like the others," Libra, the Zodiac's unassuming wallflower, finessed its way into the cosmic squad without being an animal or mythical character: That's right! Libra is the only constellation of the Zodiac named after an inanimate object. Historically associated with harmony, balance, and justice, Libra hosts intriguing cosmic objects such as exoplanets potentially harboring liquid water – a crucial ingredient for life. Though some claim it to be faint, this balanced beauty is far from invisible in the night sky.

6. Instagram Influencer Beta Librae

If Beta Librae were an Instagram influencer, it'd have us scratching our heads over its ever-changing #nofilter hue: Sometimes tagged as white, blue-white, and even the rare greenish glamour – all while secretly hiding a potential co-star from its audience. The real truth: Beta Librae, the brightest star in the Libra constellation, has a high temperature that produces light perfect for studying interstellar gas and dust. Its color perception varies for observers, and it's even suspected to have an unobservable companion star due to periodic variations in its magnitude.

7. Scorpius' Claws Turned Scales

Before Scorpius gave up on its New Year's resolution to diet and shed a few pounds: Libra was actually part of the constellation Scorpius, representing its claws in ancient Greek mythology, but decided to strike out on its own as the balanced "Scales." The Babylonians and Romans must have also appreciated the claw's newfound independence, as they adopted the Scales into their stellar lineup, representing balance and justice with a sneaky cameo from Virgo.

8. Libra's Oldest Celestial Guest

Next time you're at a cosmic party, don't miss out on meeting the great-great-great-great-great (you get the gist) granddaddy of stars who's been around since the Big Bang, just chillin' in the Libra constellation: Methuselah, comfortably seated at a grand old age of 14.46 billion years, is a mere 200 light-years away and proudly holds the title of the oldest known star in the universe. Now that's what you call a celestial vintage!

9. Libra: Fall's Elegant Equinox Host

Move over, Aries, there's a new sheriff in town: Libra takes center stage as the constellation that holds the autumnal equinox, marking the perfect equilibrium between night and day. And just like a true socialite, Libra loves showing off her dazzling celestial gems like the bright globular cluster NGC 5897 and the shining binary star Beta Librae. Serious reveal: When the Sun crosses the celestial equator at the first point of Libra, it signals the beginning of fall in numerous cultures and introduces the astrological sign of Libra, making this constellation far more than just a pretty face in the sky.

Libra's Escape from Scorpio's Grasp

10. Libra's Escape from Scorpio's Grasp

In a celestial game of "Quit Clinging to My Feet!", the Libra constellation finally managed to shake off Scorpio's reach and become a star in its own right: Originally, the two brightest stars of Libra, Zubenelschamali and Zubenelgenubi, were actually the claws of Scorpio, bearing the Arabic names for Northern Claw and Southern Claw. But over time, Libra escaped Scorpio's grasp, evolving into its modern-day identity as the Scales or the Balance, all while still paying tribute to its "clawsome" history in its design.

12. From Scorpion Claws to Justice Scales

Before the Scales of Justice tipped the celestial balance, Libra had a bit of a scorpion-esque identity crisis: this constellation once represented the Claws of the Scorpion in ancient Greece before transitioning to its fair and balanced persona in ancient Rome, where it was associated with the goddess of justice, Astraea and her heavenly weighing scales.
