What is a universe? - ANSWER-A large collection of billions of galaxies What is a galaxy? - ANSWER-A large collection of billions of stars What galaxy is the Solar System in? - ANSWER-Milky Way Galaxy Why does gravitational field strength vary? - ANSWER-The gravitational field strength of a body is dependent on the mass. A massive object like a star will have a large g-field. The Moon has less mass than Earth, so its gravitational field strength is weaker. A planet with a larger radius wil...
