Astronomers have spotted a second moon around a massive, cigar-shaped world at the fringes of the solar system. The discovery suggests multiple moons orbit many large, distant objects – but their unusual orbits raise questions about just how they could have formed.
Since 1992, when David Jewitt and Jane Luu of the University of Hawaii discovered the first Kuiper Belt Object (KBO), astronomers have been working to explore the vast and intriguing region beyond Neptune known as the Kuiper Belt. Tens of thousands of these icy KBOs await discovery as they slowly orbit the Sun.
