Question
I want to an astronaut.which subject i should read.
I was young when Neil Armstrong took the first human step on the moon forty years ago. To be an astronaut back then required more than an education and being smart. You also had to be physically fit, and more so than average. Today, the physical requirements are not as strict as they were back then. If you haven't seen the movie "The Right Stuff", about the early American space program, do so.
It is good to know sciences. Astronomy and Physics are important. A strong mathematical background is also useful. These days, any person with a specialization in any subject or discipline can be an astronaut. Pick a subject, study hard and let people know what your goal is. That is the best way to realize your dreams and desires.

Expertise
General and specific questions about the solar system and stellar and galactic astronomy, 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 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, I would have to research it more than I would like. I 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.
Experience
I have been into astronomy since I was 8 years old. I have kept detailed journals of my observations through small telescopes. Over the years I have participated in amateur observation projects for organizations like ALPO. My personal research has involved "discovering" the moons of Jupiter with a 4½-inch Newtonian reflector without any outside information like charts and tables. In a summer long project, I determined the existence of and plotted the orbits of the four major moons of Jupiter. From these observations, my data on orbital elements was surprisingly accurate (orbital radius and orbital period).
Education/Credentials
80 hours of college credits while studying physics and geophysics. Completed correspondence photography course while in high school. Took two semesters of electronics training at a community college. Studied computers and graduated from a technical school at the turn of the millennium, gaining A+ and Microsoft Certified Professional credentials.
