To obtain a Merit Badge for Astronomy, a Scout must:

1. Describe the characteristics and differences of the celestial bodies
including the sun, moon, planets, comets, meteors, stars, nebulae, and
galaxies.
[...]

Whew, that sure brings back memories. Astronomy was one of my first merit
badges circa mid 1950s. Among other things, I built a refractor and an orrery
as I recall.

I wonder what today's (21st century) requirements are like?
