Bennu has plumes! (or perhaps rather ejections of material)
QUOTE Shortly after the discovery of the particle plumes on Jan. 6, the mission science team increased the frequency of observations, and subsequently detected additional particle plumes during the following two months. Although many of the particles were ejected clear of Bennu, the team tracked some particles that orbited Bennu as satellites before returning to the asteroid’s surface. The OSIRIS-REx team initially spotted the particle plumes in images while the spacecraft was orbiting Bennu at a distance of about one mile (1.61 kilometers). Following a safety assessment, the mission team concluded the particles did not pose a risk to the spacecraft. The team continues to analyze the particle plumes and their possible causes. https://solarsystem.nasa.gov/news/877/nasa-...-big-surprises/ More images: https://svs.gsfc.nasa.gov/13154 -------------------- -- Hungry4info (Sirius_Alpha)
