List of longest-running U.S. primetime television series. This is a list of the longest running U.S. primetime television series, ordered by the number of broadcast seasons offered by a U.S. broadcast network or cable network in prime time on the show's original run. Broadcast syndication that could have been scheduled by local stations in prime time have been omitted.
The celestial equator is inclined by 23.4Â° to the ecliptic plane. The image shows the relations between Earth's axial tilt (or obliquity), rotation axis and plane of orbit. The celestial equator is a great circle on the imaginary celestial sphere, in the same plane as the Earth 's equator.In other words, it is a projection of the terrestrial equator out into space. As a result of the Earth's axial tilt, the celestial equator is inclined by 23.4Â° with respect to the ecliptic plane.At the poles, though, the celestial equator would be parallel to the horizon.) At all latitudes the celestial equator appears perfectly straight because the observer is only finitely far from the plane of the celestial equator but infinitely far from the celestial equator itself.
The equator divides the planet into a Northern Hemisphere and a Southern Hemisphere. The latitude of the equator is, by definition, 0. The length of Earth's equator is about 40,075.0 km, or 24,901.5 miles.The equator is one of the five main circles of latitude based on the relationship of the Earth's rotation and plane of orbit around the sun.he surface of the Earth at the equator is mainly ocean. The highest point on the Equator is 4,690 m, at 77 59â²31 W on the south slopes of Volc n Cayambe (summit 5,790 m) in Ecuador. This is a short distance above the snow line, and is the only point on the Equator where snow lies on the ground.
