Tropic of Cancer
2013-02-19 16:11:13

The Tropic of Cancer, which is also referred to as the Northern tropic, is the circle of latitude on the Earth that serves as a marker for the most northerly position at which the sun may appear directly overhead at its zenith. This event happens once per year, at the time of the June solstice, when the Northern Hemisphere is tilted towards the Sun to its maximum degree. Its Southern Hemisphere counterpart, marking the most southerly position at which the Sun might appear directly...

Equator

An equator is the intersection of a sphere’s surface with the plane that is perpendicular to the sphere’s axis of rotation and midway between the poles. The Equator is normally referred to the Earth’s equator: an imaginary line on the Earth’s surface halfway between the North Pole and the South Pole, separating the Earth into the Northern Hemisphere and Southern Hemisphere. Other planets and astronomical bodies have equators that are similarly defined. The Equator is approximately...

The Summer Solstice, or "Midsummer," derived from the Latin sol (sun) and sistere (to stand still), occurs exactly when the Earth's axial tilt is most inclined towards the sun at its maximum of 23° 26'. This is the time when the Sun is at its highest, or most northerly, point in the sky in the Northern Hemisphere. Except in the polar regions, where daylight is continuous for many months during the spring and summer, the day on which the Summer solstice occurs is the day of the year with...

Autumnal Equinox -- In astronomy, is the equinox at the beginning of autumn in the northern hemisphere: the moment when the sun appears to cross the celestial equator, heading southward. The equinox occurs around September 22-24, varying slightly each year according to the 400 year cycle of leap years in the Gregorian Calendar. In the southern hemisphere, the equinox occurs at the same moment, but at the beginning of spring. There are two conventions for dealing with this: either the...
