Asteroid belts and Oort cloud in other solar systems

Observations with the Spitzer telescope have discerned two rocky asteroid belts and an icy outer ring surrounding our Sun’s doppelgänger Epsilon Eridani that could have been shaped by evolving planets. Epsilon Eridani, visible to the naked eye and located just 10.5 light years away in the constellation Eridanus, is marginally smaller and cooler than our own Sun, but at just 850 million years old is providing insight into how our Solar System evolved. Epsilon Eridani has an inner rocky asteroid belt and an outer rocky belt containing around 20 times as much material also exists in the same position as Uranus.
