Lecture 2: Astronomical Numbers
An introduction and review of the basic notation and physical units we will be\nusing throughout this course. In particular, we will be using the\nMetric (SI) system for lengths, masses, times, and temperatures, and\nspecial astronomical units for distances (AU and Light Years) and masses\n(Earth Masses and Solar Masses) appropriate when discussing\ninterplanetary and interstellar scales.
