The Astronomical Numbers game

[jfribrg]

Ok folks, here is yet another game for everyone. The rules are simple. Each post states the next natural number in sequence, along with an astronomy/space flight connection. I will start off with the first 3 so that the idea is clear, and thereafter each post will be a single number. It should be easy in the beginning. As the numbers get larger, it should become rather difficult (and more fun)

1 - the Earth is 1 AU from the Sun ( I know that's almost cheating since an AU is defined that way)

2 - The number of stars in a binary system, and the number of moons of Mars

3 - The number of astronauts on an apollo moon mission.

your turn.

6 - The number of Apollo LM descent stages currently resting on the moon.

[ToSeek]

7- Number of moons in the solar system larger than Pluto.

[banquo's_bumble_puppy]

8- the number of planets in our solar system until Pluto was discovered in 1930

[The Supreme Canuck]

9 - The number of times I cursed to the heavens that banquo beat me to that answer.

[Roy Batty]

10 - inch telescope & 10 foot observatory 8)

[Arneb]

11 - the number of manned Apollo flights.

[jfribrg]

12 - number of days scheduled for the upcoming shuttle mission

[ToSeek]

13 - number of non-spiral galaxies in Messier's list

14 - the number of orbital Mercury and Gemini flights

[Moose]

15 - Apollo flight that first used the rover and brought back the "Genesis" rock. My favorite mission for this and other reasons.

[ToSeek]

16 - Number of stars (other than the Sun) known to have multiple planets

[W.F. Tomba]

17: the final Apollo mission.

[Fram]

18: the number of named moons of Saturn until 2000. (Yeah, well, it's the best I could find for the moment).

[Eroica]

19: Rigel's Flamsteed designation.

[Moose]

20 - The designated number of what should have been the final Apollo moon mission.

[mickal555]

21. The number of stars brighter than 2nd mag

[ToSeek]

22. According to this page, the number of stars of magnitude 1.5 or brighter.

[A Thousand Pardons]

23. Number of whole hours the earth takes to turn on its axis

PS: I think mickal555 was lumping in Adhara (mag. 1.5) and below with the mag. 2 stars--so you're both using the same list

[Moose]

24- The number of rounded hours we measure in a day.

[ToSeek]

25 - The number of stars within 12 light years of the Sun.

PS: I think mickal555 was lumping in Adhara (mag. 1.5) and below with the mag. 2 stars--so you're both using the same list

I'm afraid I don't follow you. That list has 46 stars of magnitude 2 or brighter.

[Frog march]

first image you get if you image search on google wth "26 nasa"

[ToSeek]

27 - The total number of American manned space missions through Apollo 17 in 1972.

[Eroica]

28: distance (to nearest lightyear) to 61 Virginis

I'm afraid I don't follow you. That list has 46 stars of magnitude 2 or brighter.

Confusion between cardinals and ordinals.

Magnitude 2 => magnitude = 2.00
Second Magnitude => magnitude = 1.50 - 2.49

[ToSeek]

29: Number of different astronauts who flew on Apollo missions.

[jfribrg]

30 - approximate number of galaxies in the Local Group.

[Tobin Dax]

31 - Decapi to the nearest integer.

[ToSeek]

32: Size (in meters) of the largest radio telescope in Poland.
