πͺ Lurking on the outskirts of our solar system, the dwarf planet Sedna follows an extraordinarily elongated orbit that takes more than 11,000 years to complete. At its farthest, Sedna drifts nearly 1,000 times farther from the Sun than Earth, journeying through a realm so remote that sunlight there is only a faint, ghostly glow. β¨

πͺ Orbiting the Sun between Mars and Jupiter, the asteroid 3200 Phaethon is the parent body of the Geminid meteor shower, but unlike most meteor shower sources, Phaethon is not a traditional icy cometβit is a rocky, blue-hued asteroid. As it dives unusually close to the Sun, intense heat causes its surface to crack and release dust, producing one of Earth's most dazzling annual meteor displays from an unlikely, enigmatic source. β¨
