    Fomalhaut is unusual in several ways: On the one hand, it forms a triple system with two dwarf stars that are extremely far apart. On the other hand, two of these three stars have a belt of dust and ice - similar to the Kuiper belt in our solar system.

    Fomalhaut is relatively quite young, only about 440 million years old. As a class A star, it is much hotter than our Sun, 15 times as bright and 25 light-years from Earth. The star burns hydrogen at such a high rate that it burns out in just a billion years, which is 10% of our star's lifespan.
