Earth to sun distance change
WebSep 6, 2024 · These changes have a variety of effects in space, in Earth’s atmosphere and on Earth’s surface. The current solar cycle (Solar Cycle 25) began in December 2024 … WebBoth the apparent drift of solstices of Earth around the Sun and the global mean temperature exhibit a strong 60 year oscillation. We monitor the precession of the Earth’s elliptical orbit using the positions of the solstices as a function of Sun–Earth distance. The “fixed dates” of solstices actually drift.
