Heller et al. (2021) estimated that shortly after the Moon was formed, when the Moon orbited 10-15 times closer to Earth than it does now, tidal heating might have contributed ~10 W/m 2 of heating over perhaps 100 million years, and that this could have accounted for a temperature increase of up to 5°C on the early Earth.

The Moon is Earth's only natural satellite. It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth.
Antarctic Cold Reversal warmer Antarctic, sea level rise: 12,400: Bølling oscillation warm and wet in the North Atlantic, begins the Bølling-Allerød period (B-S) 12,400–11,500 (much discussed) Older Dryas cold, interrupts warm period for some centuries (B-S) 12,000–11,000: Allerød oscillation warm & moist (B-S) 11,400–9,500
The Moon's heavily cratered far-side. The origin of the Moon is usually explained by a Mars-sized body striking the Earth, creating a debris ring that eventually collected into a single natural satellite, the Moon, but there are a number of variations on this giant-impact hypothesis, as well as alternative explanations, and research continues into how the Moon came to be formed.

The Moon orbited Earth much closer, appearing much larger, producing more frequent and wider eclipses as well as tidal effects. [ 18 ] The Earth of the early Archean ( 4,031 to 2,500 million years ago ) may have had a different tectonic style.
We don’t know the exact details, but the Giant Impact Hypothesis is the most widely accepted explanation for how our moon formed. Skip to main content. 24/7 Help. For premium support please call
The Moon orbits Earth in the prograde direction and completes one revolution relative to the Vernal Equinox and the stars in about 27.32 days (a tropical month and sidereal month) and one revolution relative to the Sun in about 29.53 days (a synodic month).
