About this Episode
On October 10, 1846, William Lassell, an English astronomer, made a groundbreaking discovery that would forever change our understanding of the solar system. While observing the night sky through his homemade 24-inch (61 cm) reflecting telescope, Lassell spotted a faint, glimmering object near the planet Neptune, which had been discovered just a few weeks earlier.
Excited by his finding, Lassell carefully tracked the object's motion over the following nights. To his amazement, he realized that this was not just another distant star, but rather a celestial body orbiting Neptune itself! He had discovered Triton, the largest of Neptune's 14 known moons.
Triton is a fascinating world, with a diameter of about 1,680 miles (2,700 kilometers), making it larger than the dwarf planet Pluto. What makes Triton even more remarkable is its unique orbital characteristics. Unlike most moons in the solar system, Triton orbits Neptune in the opposite direction of the planet's rotation, which is known as a retrograde orbit. This suggests that Triton may have once been a Kuiper Belt object that was captured by Neptune's gravity.
The discovery of Triton was a significant milestone in the field of astronomy, as it marked the first detection of a moon orbiting a planet beyond Saturn. Lassell's achievement also demonstrated the importance of perseverance and ingenuity in scientific exploration, as he had built his telescope himself, driven by his passion for unraveling the mysteries of the cosmos.
So, the next time you gaze up at the night sky on October 10, remember the incredible discovery made by William Lassell on this date in 1846. His tireless efforts and dedication to astronomy expanded our knowledge of the solar system and paved the way for future generations of astronomers to explore the wonders of the universe.
