Tom Whiting U.S. Available View Profile Ask A Question View Past Answers	Rating N/A (Expert Not Accept Rating) Total Questions 1339	Astronomy has been my hobby/pasttime for over 50 years. Currently own 3 telescopes, the largest of which is a 30 inch Newtonian truss Dob that is portable.I taught Astronomy/Meteorology at the University Level for 13 years before retiring in 1995. Being retired and home most of the time, I am able to answer all questions relatively quickly, unless it's a new moon weekend with good observing conditions. No astrology questions please, or questions about alleged UFO picture identifications.

Jesse Martinez U.S. Available View Profile Ask A Question View Past Answers	Knowledgeability 9.63 Clarity of Response 10.0 Timeliness 10.0 Politeness 10.0 Total Questions 28	General and specific questions about solar system and galactic astronomy, cosmology, are what I can easily answer off the top of my head. For example, what is the largest planet in the solar system? How far away is the moon? Have there been any confirmed planets in orbit around stars other than the sun? How does relativity affect possible trips to the outer planets or others stars? How many stars are there? The tougher ones like explaining the big bang theory and black holes I will leave to the PhD’s. Even though I could muster an answer, but would have to research it more than I would like. Would also like to answer questions that involve Astronomy with other sciences, chemistry, biology, physics, geology and mathematics as long as they are not PhD level.
