astronomy by definition is the study of stars....astrophysics is the study of the physics and mechanics of universe....ader part astrophysics yang overlap dgn astronomy dan astrology....ader part yang tak overlap...
so, org astronomy kaji kedudukan bintang, size, spectrum cahaya, planets etc.
org astrophysics study gravity, relativity, thermodynamics, electromagnetics, radiowaves, quantum mechanics....
so, kalau nak classifykan....paling besar astronomy subsetnyer astrology, astrophysics

Well.......

Technically, solar system is not shrinking. Our solar system is made of not only planet, but also other objects that are orbiting our sun including dwarf planets and asteroids. So, Pluto is still a member of our solar system despite its new dwarf planet status.. |
