The Earth goes around the Sun at a speed of about 30 km/second. You can multiply that by 60 to convert to km/minute, again by 60 to convert to km/hour, etc.
40,100 kilometers.

Measurements taken from space show the Earth to be round in shape, with a diameter of approximately 12,742 kilometers at the equator. The Earth's circumference is approximately 40,075 kilometers.
Sun's Gravitational force.
Gravity..
The ancient Greeks had worked out that the world was round by looking at the shadow that the Earth makes on the moon. Colombus knew it was round.
The earth's gravity field makes everything push into the earth like a bubble arround the planet. This makes it seem like the earth is flat.
Earth is round because of the gravity around it makes it all shaped in the old or ''new''earth is now what we call a sphere or a ball not a circle because that is only 2D not 3D.
It is called a great circle and the plane that circle makes must pass through the geometric center of the globe. The largest circle that can be drawn round the Earth is the great circle round its middle, the "equator" this is because the spinning of the earth makes it 'fatter' round the middle.
No. It's much slower. The Earth takes a day to spin round. The Moon takes a month.
The moon orbits around the Earth approximately once every 27.3 days. This period is known as a synodic month or lunar month.
At it point of aphelion in its elliptical orbit Round the Sun. This happens on the 4th of July each year. At this moment the Sun - Earth distance is 152,102,196 kilometers.
