WebEarth and the Moon orbit about their barycentre (common centre of mass), which lies about 4,670 km (2,900 mi) from Earth's centre (about 73% of its radius), forming a satellite system called the Earth–Moon system. On average, the distance to the Moon. With a mean orbital velocity the Moon covers a distance approximately its diameter, or about ... WebVelocity. Under standard assumptions, no other forces acting except two spherically symmetrical bodies m 1 and m 2, the orbital speed of one body traveling along an elliptic orbit can be computed from the vis-viva equation as: = where: is the standard gravitational parameter, G(m 1 +m 2), often expressed as GM when one body is much larger than the … how can you tell if a tsunami is coming

Earth orbits the Sun at an average distance of 149.60 million km (92.96 million mi) [1] in a counterclockwise direction as viewed from above the Northern Hemisphere. One complete orbit takes 365.249 days (1 sidereal year ), during which time Earth has traveled 940 million km (584 million mi). [2] See more Earth's orbit is an ellipse with the Earth-Sun barycenter as one focus and a current eccentricity of 0.0167.
