Wait, what? Earth used to have a backup moon! 🤯 For hundreds of millions of years, our main Moon co-existed with a smaller 'sibling,' trapped in the same gravitational orbit. Scientists believe this ancient companion is the reason the far side of the Moon looks so different today!

Discover the mind-blowing science behind the two-moon theory:

How the small moon got trapped in Earth's 'sweet spot.'
Why the collision with the main Moon was slow (just 2-3 km/s) and gentle, not explosive.
The bizarre way this ancient impact created the massive 50 km thickness and mountainous terrain on the Moon's far side.

Our solar system's hidden history is literally written all over the night sky! Share this amazing fact if you didn't know it!
