Earth’s distance from the Sun, physical properties, and geological history have allowed life to evolve and exist on Earth. There are several million species of life on our planet with scientists believing there are more species that have yet to be discovered. Diameter:7,926 miles (12,760 km...
Earth - Planet, Atmosphere, Geology: The mean distance of Earth from the Sun is about 149,600,000 km (92,960,000 miles). The planet orbits the Sun in a path that is presently more nearly a circle (less eccentric) than are the orbits of all but two of the

Planets with short orbital periods (roughly under 10 days) are common around stars like the Sun1,2. Stars expand as they evolve and thus we expect their close planetary companions to be engulfed, possibly powering luminous mass ejections from the host star3,4,5. However, this phase has ...

aIts average distance from the Sun is about 36 million mi (58 million km), but its highly elliptical orbit carries it 7.5 million mi (12 million km) nearer to and farther from the Sun. It is the second-smallest major planet (after Pluto), having a diameter of about 3,030 mi (4,...
From a distance, the Earth appears nearly round. People often describe it as “round” or “spherical” in everyday language, which is why. However, for more accurate descriptions, it is essential to consider the oblate spheroidal shape of the Earth. ...

A planet orbits a Sun-like star at an orbital distance of 40 AU. What is its orbital period? Johannes Kepler: Johannes Kepler developed the Laws of Planetary Motion in the 17th century. Kepler's 3rd law applies to this situation. The simplified formula to cal...
