Summary
Astronomers may have discovered a rare contact trinary in the asteroid belt: asteroid 44 Nysa appears to be three distinct bodies fused together. High-resolution observations reveal a striking three-lobed shape, while a tiny moon orbiting Nysa is helping scientists measure its mass and density. The findings could reveal whether Nysa is solid rock or a rubble pile—and how the earliest planetary bodies formed. Thank you for listening to Bedtime Astronomy — your guide to the cosmos.
