An observer standing on the Earth's equator visualizes the celestial equator as a semicircle passing directly overhead through the zenith.
The true equatorial plane must always be perpendicular to the Earth's spin axis.
Despite its name, no part of Equatorial Guinea's territory lies on the equator.
Places on the equator experience the quickest rates of sunrise and sunset in the world.
The surface of the liquid behaves as an elastic membrane in which surface tension appears, allowing the formation of drops and bubbles.
North or south of the equator day length increasingly varies with the seasons.
The equator is the intersection of the Earth's surface with the plane perpendicular to the Earth's axis of rotation and containing the Earth's center of mass.
Celestial objects near the celestial equator are visible worldwide, but they culminate the highest in the sky in the tropics.
The country that comes closest to the equator without actually touching it is Peru.
The effect is quite small, and the width of a line marking the equator on almost any map will be much wider than the error.
At the equator, Venus' surface rotates at 6.5 kilometers per hour; on Earth, the rotation speed at the equator is about 1,600 kilometers per hour.
The equator is modeled exactly in two widely used standards as a circle of radius an integer number of meters.
Temperatures near the equator are high year round with the exception for periods during the wet season and at higher altitudes.
The equators of other planets and astronomical bodies are defined analogously.
The celestial equator is a great circle on the imaginary celestial sphere, in the same plane as the Earth's equator.
The imaginary circle obtained when the Earth's equator is projected onto the sky is called the celestial equator.
The Sun, in its seasonal movement through the sky, passes directly over the equator twice each year, on the March and September equinoxes.
The highest point on the equator is 4,690 meters (15,387 ft), at 00°00?00?S, 77°59?31?W, on the south slopes of Volcбn Cayambe (summit 5,790 meters (18,996 ft)) in Ecuador.
The equator is one of the five main circles of latitude that are based on the relationship between the Earth's axis of rotation and the plane of the Earth's orbit around the sun.
The rainy and humid conditions mean that the equatorial climate is not the hottest in the world.
