Knowledge of the location of Earth has been shaped by 400 years of telescopic observations, and has expanded radically since the start of the 20th century. Initially, Earth was believed to be the center of the Universe, which consisted only of those planets visible with the naked eye and an outlying sphere of fixed stars. [1]
Original - A diagram of Earth’s location in the Universe in a series of eight maps that show from left to right, the Earth, inside the Solar System, inside the Solar Interstellar Neighborhood, inside the Milky Way, inside the Local Galactic Group, inside the Virgo Supercluster, inside our local superclusters, and finally finishing inside the entire observable Universe.
Earth's location in the Universe. Universe – all of time and space and its contents. Observable universe – spherical region of the Universe comprising all matter that may be observed from Earth at the present time, because light and other signals from these objects have had time to reach Earth since the beginning of the cosmological expansion.
Map is one of the most precise measurements of how ‘stuff’ is distributed through the cosmos
Earth is rounded into an ellipsoid with a circumference of about 40,000 km. It is the densest planet in the Solar System. Of the four rocky planets, it is the largest and most massive. Earth is about eight light-minutes away from the Sun and orbits it, taking a year (about 365.25 days) to complete one revolution.

The turtles rely on Earth’s magnetic field to help them navigate in two ways. A magnetic map aids with location tracking, and a magnetic compass orients them in the right direction.
