It takes Pluto over 248 years to orbit the Sun. One reason Pluto takes so long to orbit the Sun is the length of its orbit. Pluto's orbit covers a distance of 23 billion miles (37 billion km). That's about twice as far as Uranus and four times farther than Saturn. Another reason is the farther a planet is from the Sun, the slower it moves. Pluto is the slowest-moving planet. Pluto's orbital velocity is only 10,500 mph (16,900 kph).
