It’s called the International Astronomical Union, and they’re the ones who work out the new names for stars, and sometimes de-planet beloved Kuiper Belt Objects.

We learned how to figure out the ages of objects in the Solar System, now we push out into the deeper Universe. What about stars, galaxies, and even the Universe itself? How old is it?

Today we push our aging curiosity out into the Solar System to ask that simple question: how old is it and how do we know? What techniques do astronomers use to age various objects and regions in the Solar System?
