The Moon could have formed in just five hours after the giant impact that produced it, a timescale dramatically shorter than earlier estimates, according to a new modeling study released this week. Southwest Research Institute researchers introduced temperature‑dependent rock strength into impact simulations, replacing the common assumption that the colliding proto‑Earth and Theia behaved as strength‑less fluids.
The study is outlined in a EurekAlert release and examined by Space Daily, while Space published a feature summarizing the findings and Inshorts reported the five‑hour claim. Planetary scientists now have a tighter window for the Earth‑Moon collision, which could sharpen estimates of when the event occurred and reshape models of early solar‑system dynamics.
The rapid‑formation scenario will be examined against isotopic measurements of lunar and terrestrial rocks, and researchers plan a series of high‑resolution simulations exploring different impact angles and velocities. Results are slated for presentation at upcoming planetary science conferences, where the community will assess whether the five‑hour timeline can be reconciled with existing geochemical evidence.

Questions people are asking
What timescale does the new study propose for the Moon’s formation?
The modeling indicates the Moon could have formed within about five hours after the impact.
Which organization led the modeling effort?
Researchers from Southwest Research Institute conducted the simulations.
How does this scenario differ from earlier Moon‑formation simulations?
Earlier models treated the colliding bodies as strength‑less fluids, producing a slower, disk‑assembly process, whereas the new approach adds temperature‑dependent rock strength to enable rapid coalescence.
