Potpourri meetings feature a series of short presentations on various astronomy and space topics given by members of the Mississauga Centre. The meeting is open to the public and is free. The meeting will be held Friday Oct 4 from 8:00 to 10:00 p.m. at The University of Toronto, Mississauga Campus, in lecture hall SE2074 in the William Davis Building.

Host: Allan Connery


John Burgener: “The Influence of Dwarf Planets on the Stability of Objects in the Kuiper Belt”
The Kuiper Belt is believed to be the main source of short period comets. John shall review the orbits of dwarf planets traveling through the Kuiper Belt and the numbers of Kuiper Belt Objects, and shall show that KBOs often have their orbits changed by close passes to dwarf planets, causing a dramatically much higher rate of formation of short term comets than presently expected. This leads to the conclusion that Earth should be hit by comets often in history.

Randy Attwood: “Transit of Mercury”
Randy will tell us everything that we need to know about this relatively rare astronomical event that will next occur on November 11. Better not miss this one because the next one will be in 2032!

Various presenters: “SNOLAB Part 1”
On September 13th, 16 lucky Mississauga Centre members had the privilege of going deep underground on a tour of SNOLAB. In part 1, we will tell you about SNOLAB’s Mission and Purpose: An overview of the origins of SNOLAB from its inception as the Sudbury Neutrino Observatory (SNO), designed to answer the missing solar neutrino problem to its current focus on neutrino and dark matter physics. (In part 2, which will be presented at the November 8 Potpourri meeting, we’ll cover some of the science in more detail.)

Enter off of Mississauga Road. Park in lot 4 or in the parkade across from the fitness centre south of the Davis Building. Enter through the Fitness centre, walk up the stairs until you reach the main corridor then turn right. (If you need an elevator, follow the corridor to the right of the stairs, then go up to the main floor). Look for the Mississauga Centre sign in front of the lecture room.

After the meeting, join us at at a local watering hole (location announced during the meeting) for more fun!
