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.Know More
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.Learn more about Planets
The five planets which are visible from Earth, using the naked eye, include Saturn, Jupiter, Mars, Venus and Mercury. Because of difference in their orbits, though, it is rare for all of them to be visible in the night sky at the same time, explains National Geographic.Full Answer >
Venus is the third smallest planet in the solar system and is around 95 percent of the total size of the Earth. Both Earth and Venus are dwarfed by the largest planet in the solar system, Jupiter, which is more than 13 times their size.Full Answer >
The five planets most visible from Earth are Venus, Mercury, Mars, Jupiter and Saturn. These five are the closest planets to Earth. Without knowing how to identify these planets, people can mistake them for stars in the night sky.Full Answer >
In addition to Earth, the terrestrial planets of Mars, Venus and Mercury have oxygen in their atmospheres. The atmospheres of these planets, along with the others in the solar system, contain many different substances. The amount of oxygen in their atmospheres varies; Earth contains the most oxygen while Mars and Venus have smaller amounts and more carbon dioxide.Full Answer >
