It next happens with the southward equinox on Wednesday, 22 September, 2021 when the Sun will cross into the southern hemisphere.Leaders in Earth science data, bringing the benefits of space to all Australians. On this date the Sun moves across the celestial equator, essentially moving into the other hemisphere. What is the difference between an equinox and a solstice?Įquinox literally means equal night, when the lengths of the day and night are identical. So below the equator it’s the beginning of winter. The Tropic of Cancer can be seen on maps precisely 23.5° north of the equator.ĭuring this time the northern hemisphere gets more light and heat from our star the days are longer so the Sun is in the sky for longer, and it’s directly overhead, so more intense.Įxactly the opposite happens in the southern hemisphere, where the June solstice sees the Sun at its lowest in the sky. June’s solstice occurs when the north pole is tilted towards the Sun, which sits directly over the Tropic of Cancer. Solstice is connected only to the fact that Earth spins on an axis that is tilted by 23.5°. It’s the longest day and shortest night of the year for the northern hemisphere.Ĭounter-intuitively it’s got nothing to do with how close Earth is to the Sun, which occurs on the date of perihelion on January 2, 2021. while the equinoxes result in an equal amount of daylight and darkness across the planet. The solstices cause the longest and shortest day of the year. Where to watch: Facebook Live When is solstice sunrise from Stonehenge: What happens?
