    3rd Annual Astronomy Challenge

    It's time for the next Astronomy Challenge! This is another Bricker quiz, like the first one, or the second one, with similar rules. The previous challenges were in GA, but I have moved this one to BABBling. Only one answer per question, this time. Remember, some of these questions can have more than one right answer. Part of the game is to determine which "right" answer I am looking for--so this contest is all about me. It is sometimes deliberately deceptive, but I think anyone who finishes the quiz will learn something. I know I always do--sometimes I change my answers.


    1. What year did the fiftieth star appear on the USAn flag?
    2. What is the maximum latitude that can have the moon directly over head?
    3. What automobile make is named after an asterism?
    4. What day of the year has the worst time to see the Milky Way? (to nearest week)
    5. What comes next in this sequence: Uranus, Neptune, Pluto?
    6. Which gravity is stronger on the moon, the Sun's or the Earth's? (see question 6 of the first challenge)
    7. To the nearest hundredth of a second, how long does it take the Earth to rotate? (see question 1 of the first challenge, or question 9 of the second one)
    8. When was Io discovered? (to within ten years)

    I'm curious why you both answered question 4 the way you did.

    PS: I am not taking off for spelling errors (hi Gethen)

    Normally, I wait for a couple posts before updating scores, but I'm going to be away for a while. Wally, how did you come up with your answer to number two?

    PS: You all are invited to try again, even to crib off others entries.

    2. Should be 23.5 degrees N, but since the Moon isn't perfectly on the ecliptic (5.2 degrees), 28.7??
    3. Subaru
    4. Wild guess: Mid November
    5. Sedna (Trick question?)
    6. The sun's gravity seems to be twice as strong. 330,000/(400)^2
    7. 23 hr 56 min .04 seconds
    8. 1610 I think.

    Very good answer to number five gritmonger! I would never have thought of that.

    I can see that there are at least two of these that are going to be trouble. Maybe I'll give some hints periodically. I know we're coming on the weekend, but I'd like to break the Challenge participation record, so give it a try, it can't hurt.

    Nearest degree accuracy is enough, unfortunately.

    Trick question. Everybody knows that there are only 47 states.
    4. What day of the year has the worst time to see the Milky Way? (to nearest week)
    The day that the store ran out and I had to get a Twix instead.
    5. What comes next in this sequence: Uranus, Neptune, Pluto?
    I'll guess Dopey, but I don't remember a Disney character named Uranus.
    7. To the nearest hundredth of a second, how long does it take the Earth to rotate? (see question 1 of the first challenge, or question 9 of the second one)
    Exactly 1 day.
    8. When was Io discovered? (to within ten years)
    Captain Eo was discovered in 1986.

    That was the same answer Candy gave. Unfortunately, also wrong.

    5. Charon

    6. Earth

    7. 23hr 56min 0.04 sec

    I'll start a mini quiz on my own.

    1. Who discovered Ceres, and when?

    2. What is the 2nd brightest globular cluster as seen from Earth?

    3. In what constellations are the Large and Small Magellanic clouds in?

    4. What's the brightest star in the Northern celestial sphere?

    5. What are the largest and smallest constellations (modern borders)

    6. What comet is the origin of the Leonids?

    7. What is the name of the red dwarf star that will get closer than 1 ly in 1.4 million years?

    8. Name the most luminous star within 1,000 ly.

    9. Name 10 stars brighter than the one above.

    10. How long are the sidereal and synodic periods of the moon, to the closest tenth of a day?

    Fairly easy for you astronomy junkies here.

    earthman2110 is leading in the Most Inventive Nitpick category with USAN, but in that vein I'm going to have to claim that there is a difference between 4.1 and 4.10--that was a tough one. I've already helped you out by the last "hints" but I can see by the spread on the 4th question that I should tell you what my criteria was there too--it was that the plane of the Milky Way would be close to the horizon at local midnight, and due to an error on my part I've had to go back and accept two posters's answers that I didn't before.

    I was wondering how I managed to go from 4 right to 6 right by only changing one answer.
