NASA Sign up for CNN’s Wonder Theory science... Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes and 4 seconds with respect to other distant stars ( see below ). Earth's rotation is slowing slightly with time; thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth's rotation. See more Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space. Earth rotates eastward, in prograde motion. As viewed from the northern See more In rotational axis Earth's rotation axis moves with respect to the fixed stars (inertial space); the components of this motion are precession and See more • Allais effect • Diurnal cycle • Earth's orbit • Earth orientation parameters See more 1. ^ See Fallexperimente zum Nachweis der Erdrotation (German Wikipedia article). 2. ^ When Earth's eccentricity exceeds 0.047 and perihelion is at an appropriate equinox or solstice, … See more Among the ancient Greeks, several of the Pythagorean school believed in the rotation of Earth rather than the apparent diurnal rotation of the heavens.

WebThe Earth is a perfect sphere of radius R E =6,371 km (3958.756 miles) Thus, the Earth rotational speed on the Equator is 2*π*R E /t=2*π*6371/24 km/hour = 1 667,92 km/h or 2*π*3958.756/24 = 1036.40 miles/hour If the Earth is a perfect sphere, simple trigonometry shows us that R lat = R E *cos (lat). churches in wolf creek montana
