Comet-A comet is a relatively small solar system body that orbits the Sun. When close enough to the Sun they display a visible coma (a fuzzy outline or atmosphere due to solar radiation) and sometimes a tail. Asteroid-Asteroids are small solar system bodies that orbit the Sun. Made of rock and metal‚ they can also contain organic compounds. Asteroids are similar to comets but do not have a visible coma (fuzzy outline and tail) like comets do. They have also been called planetoids‚ especially the

Space exploration is crucial to new discoveries in science‚ that will benefit society. Space exploration has changed the world around us by providing an inside look worlds around us‚ even in our own solar system. The ability to travel through space has given us a new perspective on our solar system‚ by being able to view how nature works outside of our own planet. Earth is a unique planet. So unique that our technology today has not discovered any other planets or satellites that could sustain human

The number seven was chosen because the Greeks believed

around the sun‚ is called the corona‚ which means “crown” in Latin. The corona extends into space for millions of kilometers. It gradually thins into streams of electrically charged particles called the solar wind. Features on or just above the sun’s surface include sunspots‚ prominences‚ and solar flares. Sunspots are areas of gas on the sun’s surface that are cooler than the gases around them. Cooler gases don’t give off as much light as hotter gases‚ which is why sunspots look darker than the

past years there have been many space probes launched and even more discoveries made by them. These probes are helping people to better understand our solar system and everything it. They are also helping to make many new discoveries. What exactly is a space probe? A space probe is an unmanned space vehicle that is designed to explore our solar system and everything in it by using very high-tech instruments. Some common instruments that you will find on a spacecraft include

geological history of Earth follows the major events in Earth’s past based on the geologic time scale‚ a system of chronological measurement based on the study of the planet’s rock layers (stratigraphy). Earth formed about 4.54 billion years ago by accretion from the solar nebula‚ a disk-shaped mass of dust and gas left over from the formation of the Sun‚ which also created the rest of the Solar System. Earth was initially molten due to extreme volcanism and frequent collisions with other bodies. Eventually

1705 by English astronomer Edmond Halley‚ who it was eventually named after. Halley ’s Comet last appeared in the inner Solar System in 1986 and won’t appear again until mid-2061. Although the nucleus of the comet itself is not that large‚ the coma can extend to a very large size. As the gas molecules in the coma are ionized by the solar ultraviolet radiation pressure from the solar wind‚ a stream of particles emitted by the Sun‚ pulls the coma ’s ions out into a long tail‚ which may extend more than
