Technically, anything that is in orbit around Earth is technically a satellite, but the term "satellite" is typically used to describe a useful object placed in orbit purposely to perform some specific mission or task. We commonly hear about weather satellites, communication satellites and scientific satellites.. EARTH IN SPACE STUDY GUIDE 1.The path one object makes around another is called a(n) _______________. ORBIT 2. A complete journey around the sun revolution 3. Imaginary line between the North and South Poles on which the Earth rotates: Before, you learned. • The motions of planets and other nearby objects are visible from Earth . • Light and other forms of radiation carry information about the universe. Now, you will learn. • How astronauts explore space near Earth . 22.1 Our View from Earth . Stars seem to move but Earth is actually moving west to east. So objects in the sky seem to rise in the east & set in the west . North star, Polaris is above North Pole and stars around it seem to form a circle-always present in Northern hemisphere.
