If you stood on Jupiter you could see many moons above you, but the further out you go in the solar system these moons get smaller and smaller. Some so small that they have been invisible to scientists. These small moons are immigrants to Jupiter and most likely captured bodies that were not part of the original composition of the planet. Have we actually discovered the majority of these moons? As instrumentation gets better we can see smaller and smaller moons. Also, if there were planets orbiting a double star system, how would they orbit? Derrick and Dave also explore black holes and how they are gobbling up asteroids. And don’t miss what’s in the night sky this week. All this and more on this week’s Sky Talk.
