1. Asteroids are relics from the time the solar system was born
Billions of years ago, when the solar system was forming, space dust and debris fused to form rocks and rubble. As the rocks churned, they rammed into one another, merged and formed planets and moons.
Asteroids are the leftover rubble from those times. They have remained unchanged over billions of years.
The reaction simplifies the production of pharmaceutically important molecules called lactones and other complex compounds.
