PROPER MOTION

We did an exercise in lab tonight that showed us that the stars are not stationary. We plotted the stars in Orion as they appear today, then using math (ugh) we plotted them one million years ago and one million years in the future. We learned that the farther the stars move away from each other, the faster they move. This exercise was challenging as I have never been good at math, but luckily the ladies at my lab table were willing to share tips on how to solve the problems.
