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 .
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.
11 sty 2024 · Pluto Observational Parameters Discoverer: Clyde Tombaugh Discovery Date: 18 February 1930 Distance from Earth Minimum (10 6 km) 4284.7 Maximum (10 6 km) 7528.0 Apparent diameter from Earth Maximum (seconds of arc) 0.11 Minimum (seconds of arc) 0.06 Mean values at opposition from Earth Distance from Earth (10 6 km) 5756.78 Apparent diameter (seconds of arc) 0.08 Apparent visual magnitude 15.1 ...
Calculator for the average densities of Sun, Moon, Earth and the planets in conventional units and compared to each other.
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.
Pluto is about two-thirds the diameter of Earth's Moon and probably has a rocky core surrounded by a mantle of water ice. Interesting ices like methane and nitrogen frost coat the surface. Due to its lower density, Pluto's mass is about one-sixth that of Earth's Moon. Surface. Surface
Mercury is only slightly larger than Earth's moon. Next is Venus, a planet with a radius of 6052 km, only slightly smaller than Earth. Then comes Earth, the planet with the highest average density (5.5 g/cm³), and then Mars. Mars' radius is about half Earth's radius. It is a dusty, cold planet, but might have inhabited some form of life long ago.
