A brief overview of orbits, the physics of orbits and common phenomena related to the motion of planets with respect to each other.
I have been interested in Astronomy since I was in school. I joined OAS in December 2013. I bought my first telescope in July 2014. It is a Celestron Nexstar 130 SLT. I have been using the Nexstar and binoculars for most of my stargazing. I also enjoy helping out with the outreach program.
