What Are the Diameters of the Planets?
The diameters of the planets are as follows: Mercury is 3,032 miles; Venus is 7,521 miles; Earth is 7,926 miles; Mars is 4,222 miles; Jupiter is 88,846 miles; Saturn is 74,898 miles; Uranus is 31,763 miles; Neptune is 30,778 miles. As a result, the largest planet by diameter is Jupiter and the smallest is Mercury.
Scientists have taken several measurements of the different qualities of the planets, including their mass, diameter, density, gravity, escape velocity, rotation period, length of day, distance from the sun, perihelion, aphelion, orbital period, orbital velocity, orbital inclination, orbital eccentricity, axial tilt, mean temperature, surface pressure, number of Moons, ring systems and global magnetic field qualities. These measurements are compiled by NASA and aide in research.
Earth is the only planet that humans live on and is estimated to be approximately 4.6 billion years old. It is the densest planet in the solar system and is composed primarily of nitrogen, oxygen, argon and carbon dioxide. The earth is the fifth-largest planet in the solar system and has only one satellite, which is the moon. It takes approximately eight minutes and 19 seconds for light to reach the earth from the sun because of its distance from the sun.
