There is no concrete proof that Pluto has rings. NASA scientists think the dwarf planet may have rings, but until observation of the far away planet begins in 2015, scientists can only speculate.
Since the outer planets such as Jupiter and Saturn have rings, scientists believe Pluto might also have rings. Although Pluto is a small planet, it may have a small ring system similar to the others, and NASA has sent the New Horizons space probe out to investigate. The probe is expected to reach Pluto sometime in 2015 and when it does, it will give scientists a close-up view of the dwarf planet.
