In short, objects located along the equator are about 21 km further away from the center of the Earth geocenter than objects located at the poles. Naturally, there are some deviations in the local topography where objects located away from the equator are closer or father away from the center of the Earth than others in the same region.
The most notable exceptions are the Mariana Trench — the deepest place on Earth, at 10, m 35, ft below local sea level — and Mt. Everest, which is 8, meters 29, ft above local sea level. Meanwhile, the highest point on Earth is Mt. Saturn , which is the second-largest planet in our Solar System, is a monster in comparison to Earth. Saturn has a diameter of approximately It is quite massive as well, having the equivalent of When it comes to moons, Saturn is the King of the Moons, having 82 confirmed orbiting around it, and more await to be discovered.
The true giant in our Solar System, namely the planet Jupiter , has a diameter of around It has a mean radius of You could fit 1.
Jupiter has more than 11 times the diameter of Earth. It is the biggest planet in the Solar System. The icy giants, Uranus and Neptune , are a bit similar in size and mass; however, they are both several times bigger than our Earth. Uranus is the third-largest planet in the Solar System, and it has a diameter of around Uranus is reasonably massive, with its mass being equivalent to It would take around 63 Earth-sized planets to fill Uranus, and yes, that sounds dirty.

Earth's mass is 6. Its volume is about billion cubic miles 1 trillion cubic kilometers. The total surface area of Earth is about million square miles million square km. Its equatorial radius is km, but its polar radius is km - in other words, the Earth is slightly flattened.
Eratosthenes was measuring the polar radius, and his value using the 0. Duringthe 18th and 19th centuries, astronomers used the diameter of the Earth as the basic yardstick in determining the size of the solar system.
Today's astronomers usually do not need to know the size of the Earth for their daily research activities. Nevertheless, the diameter of the Earth still is the first step for us, the residents of this planet, in our attempt to understand the cosmic distance scale.
