Pluto is the ninth-largest and tenth-most-massive known object directly orbiting the Sun. It is the largest known trans-Neptunian object by volume but is less massive than Eris. Like other Kuiper belt objects, Pluto is primarily made of ice and rock and is relatively small—one-sixth the mass of the Moon and one-third its volume.https://en.wikipedia.org/wiki/Pluto
According to NASA Solar System Explorationshttps://solarsystem.nasa.gov/planets/dwarf-planets/pluto/in-depth/, with a radius of 715 miles (1,151 kilometers), Pluto is about 1/6 the width of Earth. If Earth was the size of a nickel, Pluto would be about as big as a popcorn kernel.
Pluto’s orbit around the sun is unusual compared to the planets: it’s both elliptical and tilted. Pluto takes 248 Earth years (or 90520 days) to make one revolution around the sun. That means one year on Pluto is about 248 Earth years. Pluto takes 6 1/2 Earth days/nights to rotate, so one day on Pluto is about 6 1/2 days/nights on Earth.
