Having a more precise diameter gives scientists the ability to more accurately calculate Pluto’s average density. This is important information for scientists because it helps them understand the composition of Pluto. 1. Find the radius(r) of Pluto. 2,370 kilometers ÷ 2 = 1,185 km. 2. Find the circumference of Pluto. C = 2 π r = 7,446 km. 3.
The average density of planets in order are:- Earth, Mercury, Venus, Mars, Neptune, Jupiter, Uranus, and Saturn. For reference (1 gm/cm 3 = 1000 kg/m 3 ) . The density of water is almost 1 gm/cm 3 or 997 kg/m 3 .

Earth with ¯⇢ ⇡ 5.5gcm3, followed by Mars with ¯⇢ ⇡ 4gcm3, – the Earth’s moon and the Galilean moons Io and Europa have intermediate densities of about ¯⇢ ⇡ 3.0 to 3.5 gcm 3 ,
18 mar 2016 · Pluto's small size and low mass mean that it has a density of 1.86 grams per cubic centimeter according to recent measurements by New Horizons, about 40 percent of Earth's density.
Having a more precise diameter gives scientists the ability to more accurately calculate Pluto's average density. A greater diameter means Pluto’s density is less than we thought. If you do the math, you’ll see that Pluto’s calculated density dropped from 2,051 kg/m 3 to 1,879 kg/m 3 with this new finding.
