Throughout Earth’s history, there have been many instances of near-Earth objects (NEOs) impacting our planet, either reaching the surface or exploding above ground from the intense energy released as the object passed through the atmosphere. Asteroid impacts are natural processes that shape the surface of our planet, like volcanoes.

2022年9月14日 · According to the Giant Impact Hypothesis, 4.5 billion years ago, a planetesimal the size of Mars, dubbed Theia, slammed into Earth. The debris ejected by the impact entered orbit around our...

2025年1月23日 · Early in its existence, massive asteroids smashed into Earth with lasting consequences for our planet’s geology and life.

2017年4月25日 · The following asteroid impact events created huge craters in the past and may have affected life on earth. First on the list is the massive 118.061-mile radius Vredefort Crater located in Free State, South Africa, which hit 2 billion years ago.

This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024, all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors.

2022年2月15日 · So what does it take for an asteroid to make a dent on Earth, and which known impact events have left the biggest craters? Most space rocks that barrel into Earth's …

Asteroid impacts are significant events that can have profound effects on Earth's environment and life. These impacts can range from small meteoroids causing localized damage to massive asteroids ...

2022年12月18日 · Plenty of asteroids have struck Earth during the last few billion years, sometimes with disastrous consequences. Virginia Places explains that over the past 650 million years, there have been hundreds of asteroids that impacted Earth with enough force to leave a crater over 12 miles in diameter.

2024年8月30日 · Earth has been bombarded by asteroids and comets throughout its 4.5 billion year history. While the vast majority burn up in the atmosphere, some of the larger ones have impacted the surface, leaving behind massive craters. Today, around 190 impact craters have been identified on Earth. Here is a detailed look at the 10 largest…

2023年8月10日 · The latest evidence suggests Earth and the other planets in the solar system were subject to intense asteroid bombardments until about 3.2 billion years ago, and sporadically since.
