November 19 – 19521 Chaos

We have a cubewano today! It is Kuiper-belt object 19521 Chaos, which was discovered by the Deep Ecliptic Survey on November 19th, 1998. Chaos is about 600 km in diameter, and may well be a dwarf planet, not much smaller than Ixion and Varuna. It orbits between a perihelion of about 40.9 AU and an aphelion of just under 50.6 AU, and spends more than 300 Earth years completing a single orbit of the Sun (or 1 Chaotian year, obviously).


1996 – Launch of space shuttle Columbia on mission STS-80 (19 days late). At 17 days and 15 hours this became the longest shuttle mission, and comprised commander Kenneth D Cockrell, pilot Kent V Rominger, and mission specialists F Story Musgrave, Thomas D Jones, and Tamara E Jernigan.  Musgrave was on his sixth flight, a record at the time, and became the only person to fly all five shuttles.
