3. Stars and our Sun The definition of a star is a ball of gas that gives off light and heat. It has the same body like the sun. Stars are classified by their spectra and temperature. Now the sun is 4.6 billion years old. There are spots on the sun’s surface. The spots come from the heat from the middle of the sun.

4. Saturn Saturn is a outer planet. Its 72,367 diameters away from our planet, - 270 ˚degrees,890.7 million mi away from the sun, and Saturn is a gas giant. Two interesting facts are that Saturn has 72 moons and the rings are not solid the rings are icy.

5. Earth  Earth is a inner planet. It is 7,917,500, mi- diameters and 15ºc. It is 92.96 mi away from the sun. Also Saturn is a rocky planet. Two interesting fact is the hottest temperature recorded was on Earth was 70.7ºf in 2005. Another interesting fact is the largest terrestrial planet. Terrestrial planets are inner planets made of silicate rocks or metal.

6. Comets  Comets are cosmic snowballs of frozen gases, rock and dust. Comets form to gas when close to sun. Comet heats up and spews dust and gases into a giant glowing head larger than most planets.sometime

7. The nucleus is the solid, central part of a comet, popularly termed a dirty snowball or an icy dirtball. A cometary nucleus is composed of rock, dust, and frozen gases. When heated by the Sun, the gases sublimate and produce an atmosphere surrounding the nucleus known as the coma. The coma is the nebulous envelope around the nucleus of a comet. It is formed when the comet passes close to the Sun on its highly elliptical orbit; as the comet warms, parts of it sublimate. The Sun begins to heat the nucleus of the comet releasing gas and dust into a temporary atmosphere called the coma. When sunlight strikes the dust particles in the coma, it exerts a pressure (called radiation pressure) which pushes the dust particles from the coma and into a dust tail. The Sun begins to heat the nucleus of the comet releasing gas and dust into a temporary atmosphere called the coma. Reaching lengths of hundreds of millions of kilometers, the gas tail is composed of molecules ionized by ultraviolet light from the Sun.

8. Meteor A meteor is the flash of light that we see in the night sky when a small chunk of interplanetary debris burns up as it passes through our atmosphere. " Meteor " refers to the flash of light caused by the debris, not the debris itself. The debris is called a meteoroid.

9. Gravity  Force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.

10. Technology  Technology is a force that helps us stay on the ground and not fly away. Gravity is the collection of techniques, skills, methods and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation.
