Bennu's parent body probably formed near the solar system's water-ice line
ETH Zurich says new sample analyses suggest Bennu's parent body emerged in a transition zone cold enough for water to freeze, while Jupiter was still growing.
TLDR
Bennu's parent body probably formed near the water-ice line rather than far out in the solar system, according to new sample analyses described by ETH Zurich. The proposed birthplace was a transition zone where temperatures allowed water to freeze. The researchers suggest this happened while Jupiter itself was still growing.
