One of my favourite parts of AAS meetings is attending plenaries way out of my subfield. Pleased to be able to still do that virtually #AAS237 -in "Comets, Unseen Planets, and the Outer Fringes of the Solar System", by Scott Tremaine. I never thought about how comet brightness depends on distance^4 - 2 powers from the Sun to the comet, and 2 powers back to us on Earth. Comet Neowise over the sea.
