SCI2017_0004: Artist's illustration of the Epsilon Eridani system showing Epsilon Eridani b, right foreground, a Jupiter-mass planet orbiting its parent star at the outside edge of an asteroid belt. In the background can be seen another narrow asteroid or comet belt plus an outermost belt similar in size to our solar system's Kuiper Belt. The similarity of the structure of the Epsilon Eridani system to our solar system is remarkable, although Epsilon Eridani is much younger than our sun. SOFIA observations confirmed the existence of the asteroid belt adjacent to the orbit of the Jovian planet. Credit: NASA/SOFIA/Lynette Cook

This artist diagram based on observations from NASA Spitzer Space Telescope compares the Epsilon Eridani system to our own solar system. The two systems are structure

This artist conception shows the closest known planetary system to our own, called Epsilon Eridani. Observations from NASA Spitzer Space Telescope show that the system hosts two asteroid belts.
