What happens when an asteroid hits the Moon and Earth impact

TL;DR

An asteroid named 2024 YR4 once thought to threaten Earth may instead strike the Moon, potentially creating a bright flash and a large crater while posing risks to satellites and Artemis missions. The Moon could suffer a crater about a mile wide, and Earth remains shielded from impact but watches for orbital effects and space program implications.

What's up, sunshine? Hope you're having a great day so far. Smell the flowers and cool the soup. We've got a great show for you today. So, grab your lunch pail, put your hard hats on. It's time to get to work. The best 10 minutes of news starts now. We begin with an update from NASA about an asteroid that was once thought to be on a collision cours... Read More

Key Insights

• 2024 YR4 was initially considered a potential Earth threat with a 3.1 percent collision probability in 2032.
• New data suggests the asteroid may instead hit the Moon, reducing risk to Earth but increasing lunar impact considerations.
• The Moon impact could create a crater about a mile across and last up to thousands of years in geological terms.
• If the asteroid strikes near the Moon’s near side, a bright flash and lunar debris would be visible from Earth.
• Such an impact could affect satellites and poses risks to astronauts affiliated with NASA’s Artemis program.
• NASA's Artemis program plans to return humans to the Moon and establish a lunar space station in future missions.
• Other stories in the broadcast include Hawaii petroglyph discoveries dating back over a thousand years and a field trip to Asheville highlighting regional culture and history.
• The report also covers how Chinese brands are expanding in the US and ongoing trade dynamics between the two countries.

Questions & Answers

Q: A real search query question about the video (e.g. 'How to...', 'What is...', 'Why does...', 'When should...'). Question 1

What would happen if an asteroid hits the Moon and how would it affect Earth and space exploration? The Moon impact could create a roughly mile wide crater and produce a bright flash, with lunar rocks potentially falling toward Earth as meteoric debris. Satellites could be affected and Artemis era plans could face additional risk considerations.

Q: What is 2024 YR4 and why is it important?

2024 YR4 is an asteroid monitored by NASA that was once thought to pose a collision risk to Earth in 2032 with a 3.1 percent probability. New assessments suggest the object might instead strike the Moon, shifting the focus from planetary defense to lunar impact dynamics and exploration safety.

Q: How likely is a Moon impact compared to a Earth impact according to the video?

The video notes there is about a 4 percent chance that 2024 YR4 could hit the Moon, compared to earlier concerns about Earth impact in 2032. This shift in likelihood changes the science and safety considerations for lunar missions and communications.

Q: What would be the visible effects on Earth if the Moon is struck?

If the asteroid hits the near side of the Moon, observers on Earth could see a bright flash and debris scattering, with small moon rocks potentially entering Earth’s atmosphere and creating a meteor shower, while no direct danger to Earth itself is emphasized.

Q: What NASA programs are mentioned in relation to Moon exploration?

The CNN10 segment references NASA’s Artemis program, including plans to return humans to the Moon for the first time in 55 years and to establish a lunar space station with future missions aimed at Mars, highlighting safety and operational concerns if a lunar impact occurs.

Q: What other topics are covered in the CNN10 broadcast besides the asteroid update?

The broadcast also covers ancient petroglyph discoveries in Hawaii that may record births and significant events, and a field trip to Asheville, North Carolina, focusing on recovery after Hurricane Helene and regional highlights, illustrating a broad science and culture news mix.

Q: What is falconry as explained in the Asheville segment?

Falconry is described as hunting with birds of prey, where the bird does the killing rather than firearms or ordinary hunting methods, reflecting the educational and historical context of visitors experiencing rural and natural history.

Q: What local culture highlights are included in the Hearth of the show segment about China and the US?

The program discusses how Chinese brands are expanding in the US, including Luckin Coffee and other brands, illustrating cross-border commerce and consumer interest amid trade dynamics, and how American audiences engage with international products.

Summary & Key Takeaways

• A NASA monitored asteroid 2024 YR4 shifted from Earth on a collision course to a potential Moon impact, possibly changing the Moon’s surface with a large crater.

• A Moon strike would produce a bright flash and lunar debris that could affect satellites and astronauts under the Artemis program.

• Across additional reports, ancient petroglyphs in Hawaii and a field trip to Asheville show how science and exploration shape our understanding of Earth and space events.
