PROJECT: THE PLANETS
Lea el presente documento y conteste las preguntas que le sigue:
There arenine planets that revolve around the sun in our solar system. A planet is a body of matter that shines by reflected light. Like Earth, the otherplanets do not give off light of their own. When you see a planet shining brightly in the night sky, it is given off the sun’s light. Theseplanets travel around the sun in fixed path called orbits. A planet gravitational pull depends on two things: size and density. The term densityrefers to the amount of matter contained in a given space. A block of iron and a block of ice that are equal in size are not equal in weight; theblock of iron weighs more than the block of ice. A scientist would say that the iron is more dense; the block of iron has more matter in it.1. How many planets are in our solar system?
