* Diameter: Earth is about 7,926 miles (12,742 kilometers) in diameter, while Pluto is only 1,476 miles (2,376 kilometers) in diameter. This means Earth is about 5 times wider than Pluto.

* Mass: Earth's mass is about 5.972 × 10^24 kg, while Pluto's mass is about 1.309 × 10^22 kg. This makes Earth about 500 times more massive than Pluto.

To put it simply, if Earth was a basketball, Pluto would be about the size of a golf ball.
