I believe the answer is californium because it is used in most metals and is very strong and expensive like gold and silver
The Sun <span>produces energy by forming "Helium" in its core by the process of "Nuclear fusion"

Answer:
The gravitational force does change believe it or not, but the explaination for this is because the earths orbit is an oval (or a not circle) the closer it nears its self to the sun. the suns gravitational pull, pulls the earth to it bringing it closer and as it reaches the other side lets call this L when it reaches L it becomes the same gravitational pull reset as P is and another section over the sun lets call this M and when it reaches M its the same pull as Q, you get it now?
