<b>Earth</b> is the third planet from the Sun and the only astronomical object known to 
harbor life. ... To second order, <b>Earth</b> is approximately an oblate spheroid, whose 
equatorial <b>diameter</b> is 43 kilometres (27 mi) larger than the pole-to-pole <b>diameter</b>,
&nbsp;... The angular diameter, angular size, apparent diameter, or apparent size is an 
angular ... Thus, the angular <b>diameter of Earth&#39;s</b> orbit around the Sun as viewed 
from a distance of 1 pc is 2″, as 1 AU is the mean radius of Earth&#39;s orbit. Eratosthenes also calculated the Sun&#39;s <b>diameter</b>. According to Macrobious, 
Eratosthenes made the <b>diameter</b> of the Sun to be about 27 times that of the <b>Earth</b>. <b>Earth&#39;s</b> orbital speed averages 29.78 km/s (107,208 km/h; 66,616 mph), which is 
fast enough to cover the planet&#39;s <b>diameter</b> in 7 minutes and the distance to the&nbsp;... <b>Earth</b> radius is the distance from the center of <b>Earth</b> to a point on its surface. Its 
value ranges from 6,378 km (3,963 mi) at the equator to 6,357 km (3,950 mi) at a
