Outer Solar System's oldest bodies were rich in chondrules
Original: The oldest bodies of the outer Solar System were 83–92% chondrules — ScienceAlert
ScienceAlert reports that the oldest bodies of the outer Solar System were composed of 83–92% chondrules, the small spherical grains that formed in the early solar nebula. The finding offers new insight into how the first planetesimals assembled, suggesting chondrule-rich material was a major building block even in the outer reaches of the Solar System billions of years ago.
Why now: The finding reshapes scientific understanding of how the earliest planetesimals formed and what materials built the outer Solar System.
