ArbCom Elections 2016: Voting now open!
Added Π to Dwarf Planet
I added Π to the table and associated blurb on the dwarf planet page. Procrastination is my forte. I'm not sure about the "refined" clause: it might be presumptuous. Tbayboy (talk) 16:44, 15 April 2017 (UTC)
- Thank you. Stern and Levison (2002) considered single encounters that produce deflection angles in excess of 1 radian during a Hubble time. While that calculation may be interesting in terms of close encounter time scales, it is not at all equivalent to the IAU criterion of clearing an orbital zone.
