    brings our Jupiter total to 79. Seven of these ten are in retrograde orbit. “Retrograde” means that is the opposite direction from the rotation of the planet. The real “oddball” is a moon in the midst of the retrograde swarm that s orbiting prograde. (p 8)

  1. Saturn……………@speear40: Number 2 on Oition’s list is the Cat’s Eye Nebula. (p. 28)

  1. Mars……………@__Skynet__: Mars looks great now, but try to catch it these two nights for a spectacular show. (p. 41)

  1. Capricornus….………@Private_Michael: This constellation is smaller than Aries, has a shape like a boat, a tradition-laden name, and more to distinguish itself. More next month. (p. 45)

  1. Uranus……..@Pircano: While we might catch the 7th planet from the Sun with our unaided eyes, the eighth planet will be in the sky most of October’s evenings, but will certainly need help. (p. 47)

  1. Comet Halley…………….@__Skynet__: Yes, you might be able to see pieces, debris, actually, of this famous comet later this month. The Orionid meteors originate from the snowy-dirtball not scheduled for return until the year 2061. Everyone mark your calendars! (p. 49)


Thanks goes out to all participants, and Congratulations to everyone who got one right.
