Are they just different names for the same thing? Actually, a solstice and an equinox are sort of opposites . The seasons on Earth change because the planet is slightly tilted on its axis as it travels around the Sun. This means different points on Earth receive more or less sunlight at different times of year.
What are solstices and equinoxes? ... When the sun is furthest north or south from the equator, it’s a solstice . When neither hemisphere is tilted toward or away from the sun, it’s an equinox. They are related to the seasons because it makes the days longer or shorter, warmer or colder.
How does the equinox affect seasons?
(“Equinox” is derived from the Latin for “equal night.”) After Sunday, the sun will shine more on the southern half of our planet and less on the northern half. Summer will be over in the Northern Hemisphere, and fall will have arrived. Winter will be over in the south, and spring will begin .
The equinox in the Northern hemisphere occurs twice a year around spring and autumn. It is the time the plane of Earth’s equator passes through the centre of the sun’s disc. The solstice marks summer and winter seasons . It is the times when the sun reaches its highest or lowest point in the sky at noon.
What is difference between equinox and solstice?
Solstices designate the point where the Sun’s path in the sky is the farthest north or south from the Equator, which occurs around the 20th and 21st of June and the 21st and 22nd of December. ... The equinoxes are when the Sun is right over the Equator, in between the two Tropics.
The winter solstice in the Southern Hemisphere is June 20 or 21, while the summer solstice, the longest day of the year, is December 21 or 22. Seasons occur because Earth is tilted on its axis relative to the orbital plane , the invisible, flat disc where most objects in the solar system orbit the sun.
What are the 4 equinoxes?
- Vernal equinox(about March 21): day and night of equal length, marking the start of spring.
- Summer solstice (June 20 or 21): longest day of the year, marking the start of summer.
- Autumnal equinox(about September 23): day and night of equal length, marking the start of autumn.
How long does equinox last?
Therefore, on the equinox and for several days before and after the equinox, the length of day will range from about 12 hours and six and one-half minutes at the equator , to 12 hours and 8 minutes at 30 degrees latitude, to 12 hours and 16 minutes at 60 degrees latitude.
Is equinox twice a year?
We have an equinox twice a year – spring and fall – when the tilt of the Earth’s axis and Earth’s orbit around the sun combine in such a way that the axis is inclined neither away from nor toward the sun.
What does solstice literally mean?
Solstices. ... The solstice (combining the Latin words sol for “Sun” and sistere for “To Stand Still”) is the point where the Sun appears to reach either its highest or lowest point in the sky for the year and thus ancient astronomers came to know the day as one where the Sun appeared to stand still.
What is the equinox phenomenon?
Equinox is a unique phenomenon during which the earth’s day and night are of equal length resulting in 12 hours of daylight and 12 hours of night in every part of the earth.
Do the equinoxes change?
The dates of the equinoxes change progressively during the leap-year cycle , because the Gregorian calendar year is not commensurate with the period of the Earth’s revolution about the Sun. It is only after a complete Gregorian leap-year cycle of 400 years that the seasons commence at approximately the same time.
What’s the difference between solstice and solstice?

What happens during a solstice?
The Southern Hemisphere’s seasons are reversed. On two moments each year—what are called solstices— Earth’s axis is tilted most closely toward the sun . The hemisphere tilted most toward our home star sees its longest day, while the hemisphere tilted away from the sun sees its longest night.
Why does equinox happen?
Equinoxes occur when the axis of rotation of the earth (i.e. the line form the N to S poles) is exactly parallel to the direction of motion of the earth around the sun . This happens on just two days of the year, the spring and autumn equinoxes.
Is the solstice always on the 21st?
The dates of the solstice varies each year and may occur a day earlier or later depending on the time zone. The solstices always occur between June 20 and 22 and between December 20 and 23 with the 21st and 22nd being the most common dates.
