Lightyear update anki. Stars, dust, and gas fan out from the center of the Galaxy in long spiraling The words " solar system " refer to the Sun and all of the objects that travel around it. The galaxy we live in, the Milky Way, is a spiral galaxy. These objects include planets, natural satellites such as the Moon, the asteroid belt, comets, and meteoroids. If you were looking down on the Milky Way, it would look like a large pinwheel rotating in space. Contained in the Milky Way are stars, clouds of dust and gas called nebulae, planets, and asteroids. The Sun is the center of the solar system. This activity can be used in conjunction with the StarChild Universe Level 2 information OBJECTIVES: Examine ways of measuring distance Make inferences regarding space travel Identify the distance relationship between Earth and other objects in the Universe Develop formulas and procedures for determining measurements to solve problems Chose the appropriate metrics units and tools Calculate A galaxy contains stars, gas, and dust which are held together as a group by gravity. Light moves at a velocity of about 300,000 kilometers (km) each second. Some galaxies are called "spiral", because they look like giant pinwheels in the sky. Galaxies are labeled according to their shape. d357l pqe w3l jxm d5sgg ku1ns edaa6 rsy 7k 5hjss
