That happens on June 21.
It's the Summer Solstice for the northern Hemisphere, but it's the beginning of Winter in the Southern Hemisphere.
The latitude lines that mark the summer and winter solstices are the Tropic of Cancer and the Tropic of Capricorn. The Tropic of Cancer, located at approximately 23.5° North latitude, marks the position of the sun during the summer solstice in the Northern Hemisphere. Conversely, the Tropic of Capricorn, at approximately 23.5° South latitude, marks the position of the sun during the winter solstice in the Northern Hemisphere. These latitudes define the limits of the sun's zenith during these solstices.
Tropic of Capricorn
When the Tropic of Cancer receives the direct rays of the sun, it is called the summer solstice. This event occurs around June 21 each year, marking the longest day of the year in the Northern Hemisphere. During this time, the sun is at its highest point in the sky for locations north of the equator.
If the Earth's axis were tilted at 45 degrees, the Sun would be directly overhead at the Tropic of Cancer (approximately 23.5° N) during the summer solstice, and at the Tropic of Capricorn (approximately 23.5° S) during the winter solstice. However, with a 45-degree tilt, the latitudes for direct overhead sunlight would shift to approximately 45° N during the summer solstice and 45° S during the winter solstice. This change would significantly alter global climate patterns and the distribution of sunlight throughout the year.
A solstice is the time of the year when the difference between the length of day and a night is at a maximum. At the Summer solstice the North Pole is at its maximum tilt towards the sun so that the Tropic of Cancer is facing the sun. At the Winter solstice the North Pole is at its maximum tilt away from the sun so that the Tropic of Capricorn is facing the sun.An equinox (literally, equal night) is the time of year when the day and night are of exactly the same length. These happen during the Spring and Autumn: the Polar axis is perpendicular the the Earth-Sun axis: the sun is directly above the equator.
They are named after a constellation during the winter solstice (Capricorn) and Cancer is named after a constellation during the summer solstice.
No. That configuration occurs somewhere on the Tropic of Cancer once a year for a moment, around June 21, and somewhere on the Tropic of Capricorn once a year for a moment, around December 22.
The day is June 20 or June 21 that the solstice takes place. During the summer solstice the duration of day time is directly over the tropic of cancer.
The sun's rays hit the Tropic of Cancer around June 21st during the summer solstice and the Tropic of Capricorn around December 21st during the winter solstice. At these times, each respective tropic experiences its longest day or night of the year.
The word cancer is the Latin for crab. The Tropic of Cancer is so called because the sun was in the constellation of Cancer when it appeared directly overhead at this latitude during the summer solstice.
The latitude lines that mark the summer and winter solstices are the Tropic of Cancer and the Tropic of Capricorn. The Tropic of Cancer, located at approximately 23.5° North latitude, marks the position of the sun during the summer solstice in the Northern Hemisphere. Conversely, the Tropic of Capricorn, at approximately 23.5° South latitude, marks the position of the sun during the winter solstice in the Northern Hemisphere. These latitudes define the limits of the sun's zenith during these solstices.
The sun's rays strike the earth at 90 degrees (verticle) at their northernmost position during the summer solstice for northern hemisphere and at their southernmost position during the summer solstice for the southern hemisphere. These positions are known as the Tropic of Cancer in the northern hemisphere and the Tropic of Capricorn in the Southern Hemisphere.
When the Earth is in position M, which typically corresponds to the summer solstice in the Northern Hemisphere (around June 21), the latitude that receives the vertical rays of the sun is 23.5° N, known as the Tropic of Cancer. Conversely, during the winter solstice (around December 21), the vertical rays hit 23.5° S, or the Tropic of Capricorn. During equinoxes, the sun's rays are directly overhead at the equator (0° latitude).
The Tropic of Capricorn is so named because about 2000 years ago the sun was entering the constellation Capricornus on the December solstice. In modern times the sun appears in the constellation Sagittarius during this time. The change is due to precession of the equinoxes!!
The Tropic of Cancer is located near this latitude, more specifically along 23°27' north latitude. This represents the northernmost points that can experience direct vertical insolation (Sun directly overhead) on at least one day of the year.
The vertical rays of the sun in the Northern Hemisphere occur at the Tropic of Cancer, which is located at approximately 23.5 degrees North latitude. This is the northernmost point where the sun can be directly overhead at noon, occurring during the summer solstice around June 21.
The Tropics of Cancer and Capricorn are lines of latitude that define the Tropics. They also mark the northernmost and southernmost latitudes at which the Sun shines directly overhead at midday during the June solstice and December solstice respectively.
