    The Astronomical Numbers game

    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.

    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

    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
