  21. ⭐ 4.5 billion years ago, a star wandered close enough to reshape our entire outer Solar System.

    A 2024 study in Nature Astronomy ran 3,000+ simulations and found that a star roughly 0.8x the Sun's mass passed within 110 AU (about 0.2% of the distance to the next nearest star today) at a steep 70-degree angle.

    The gravitational handshake flung icy objects onto wild eccentric orbits, created Sedna-like bodies that swing out hundreds of AU, and even produced worlds orbiting backward, opposite to every planet.

    The best part: this wasn't even the main prediction. Retrograde objects appeared as a natural bonus that the modelers weren't looking for.

    At least 140 million Sun-like stars in the Milky Way have likely experienced a similar encounter. The Vera Rubin Observatory, which started its survey in 2025, should discover roughly 40,000 new trans-Neptunian objects and put this to the test.
