The study estimates asteroid 2024 YR4 has a 3.8% chance of hitting the Moon, not Earth.
If an impact occurs, a ~1 km crater could form with an infrared glow lasting hours.
The impact could trigger Moonquakes detectable by seismometers on the Moon.
Debris ejected from the Moon could reach Earth and produce meteors visible in the sky.
The flash on the Moon could reach brightness levels similar to magnitude –3 to –5.
Astronomers could observe the event with infrared and other instruments as the crater cools.
A coordinated observing plan could use NASA and international lunar orbiters to study aftermath.
The study maps a timeline from impact to days and years after, including potential lunar meteorites reaching Earth.
The projected event would be a rare scientific opportunity to study lunar material and impacts.
Observational timing would favor the Pacific hemisphere and sites like Mauna Kea for viewing.

New simulations show Earth’s atmosphere slowly leaks and can accumulate on the Moon’s near side over billions of years.
The team used computer simulations to show how charged atoms escape Earth and reach the Moon, especially during magnetic-tail passages.
During brief monthly alignments, the Moon travels through Earth’s magnetotail, guiding escaping atoms toward its surface.
Regolith on the Moon traps incoming atoms, slowing them and locking them into the soil over time.
Lunar samples from Apollo 14 and 17 helped validate the simulations by showing distinct Earth-derived isotopes.
Isotopic analysis distinguishes Earth-origin atoms from those formed in the solar wind.
The study describes the Moon acting as a time capsule for parts of Earth’s ancient atmosphere.
Future missions could test Earth-derived gases directly on the Moon to support life-support and propulsion needs.
The research connects space physics, magnetic fields, and lunar geology in understanding Earth–Moon exchanges.

Artemis II will launch in the coming months with four astronauts including Canada’s Jeremy Hansen on a 10-day lunar flyby.
The crew will travel around the Moon to test hardware and collect data for Artemis III’s Moon landing in 2028.
Artemis III aims to land on the Moon’s south pole, representing a key milestone in sustained lunar exploration.
The program involves 61 countries and features competition from China and plans from India to reach the Moon.
Private companies and a growing space economy are betting on lunar exploration as a long-term venture.
Space missions have historically yielded technology benefits, including medical advances and everyday tech improvements.
Canada’s involvement highlights national leadership in space exploration and potential future resources on the Moon.
The mission will also explore medical monitoring for astronauts, with potential applications on Earth in extreme environments.
The Artemis program is framed as not just exploration but also a path to new technologies and economic activity.
Artemis II will lay groundwork for future private-sector participation and international cooperation in lunar ventures.
