Default 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.

Confusion between cardinals and ordinals.

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