Earth and moon impact theory
The document discusses the formation of Earth's moon, supported by NASA's findings that the moon was created following a collision between the early Earth and a planet-sized object named Theia approximately 4.5 billion years ago. This theory, known as the giant impact hypothesis, is bolstered by new analyses of lunar rocks. Additionally, it outlines a timeline of humanity's exploration of the moon, showcasing significant milestones in lunar research.

But how did the Moon originally form? The findings from a new NASA lunar rock study provide evidence for a theory the Moon was created after another planet smashed into a young, molten Earth billions of years ago.

- 4. How the MoonFormed: Lunar Rocks Support Giant Impact Theory • The Earth's moon is thought to have formed when a Mars-sized object, called Theia, slammed into the early Earth 4.5 billion years ago, blasting out material that later coalesced into a large satellite as depicted in this artist's illustration. A new analysis of lunar rocks adds new support to this Giant Impact Hypothesis. (Image credit: NASA/JPL-Caltech) • A new analysis of lunar rocks now supports the idea that the moon was born in a gigantic collision between the nascent Earth and a mysterious planet-size rock, scientists say. • Earth formed about 4.5 billion years ago, and scientists think the moon came into being shortly afterward. The prevailing explanation for the moon's origin, known as the Giant Impact Hypothesis, is that it resulted from two protoplanets (or embryonic worlds) that slammed together — the Earth as it was forming, and a Mars-size object called Theia. A lot of debris went on to form the moon. • https://www.space.com/26142-moon-formation-giant-impact-theory-support.html
- 5. The Giant Impact •Scientists have proposed many ideas for how the Moon formed. A leading contender, the Giant Impact theory, speculates that when Earth was a young planet and just beginning to form, it was hit by another emerging planet named Theia, located nearby. The collision caused both planets to temporarily splatter apart into globs of gas, magma, and chemical elements before reforming into the bodies we know today to be the Earth and Moon. The research by Simon and Gargano is adding support that further confirms this theory.
