What is the radius and diameter of Pluto?
Size and Distance 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. From an average distance of 3.7 billion miles (5.9 billion kilometers), Pluto is 39 astronomical units away from the Sun.

Why Pluto is no longer a planet?
The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
Is Pluto still the smallest planet?
Mercury is bigger than Pluto, but it’s still considered the smallest planet because of Pluto’s designation as a dwarf planet. In 2006, the IAU determined Pluto did not meet the qualifications to be a planet because it doesn’t clear its orbital path like the other planets do.
What Colour is Pluto?
Pluto, the dwarf planet, has a wide range of colors on its surface. The majority of the planet is off-white and blue, though there is a large red spot along with streaks of yellow and orange. Space probe images of Pluto’s red spot indicate that it is heart-shaped.
Can we land on Pluto?
Unlike gas giants Jupiter and Saturn, and ice giants Uranus and Neptune, Pluto’s surface is a solid one. This means that if humans could get a space ship all the way to Pluto, the ship could land on Pluto. And, once the ship has landed, humans could exit the ship and stand on the surface of the planet.
Is there any water on Pluto?
Pluto. Dwarf planet Pluto’s surface is covered by a combination of nitrogen-rich ice and water ice. Pluto is thought to have a subsurface ocean about 100 kilometers deep. The surface of Pluto’s largest moon, Charon, contains a mixture of ices including water ice.

What planet is bigger than Pluto?
Eris, the largest dwarf planet, is only slightly bigger than Pluto, at 1,445 miles in diameter (2,326 km). Discovered in 2003, Eris orbits at an average distance of 68 AU (that is, 68 times the Earth’s distance from the sun) and takes 561.4 Earth years to circle the sun.
