Cosmos – an alternative name for the universe Meridian – a half circle extending from your horizon (altitude 0) due south through your zenith to your horizon due north. Zenith – the point directly overhead‚ which has an altitude of 90 degrees. Latitude –The angular north-south distance between Earth’s equator and a location on Earth’s surface. Longitude – The angular east-west distance between the prime meridian (which passes through Greenwich) and a location on Earth’s surface. Speed – The

Jupiter is the largest planet in our solar system. It is twice as large as all the other planets combined. It has 28 known satellites. The earliest discovered moons date back to 1610 and were discovered by Galileo. This is of interest because a future mission to Jupiter is named after this astronomer. Most of the remaining moons were discovered in the 20th century with advancement of technology. Some are discovered using better telescopes and others with missions directed towards Jupiter. Some of

Below are ten facts about Saturn and a table of statistics. FACT ONE Saturn is the second largest planet in the Solar System after Jupiter. It is so big that Earth could fit into it 755 times. FACT TWO Saturn is a slightly smaller version of Jupiter‚ with similar‚ but less distinctive‚ surface patterns. Its only main difference is its amazing rings. FACT THREE Saturn’s rings may be particles of an old moon orbiting the planet‚ smashed apart in a collision about 50 million years ago. FACT FOUR

Space exploration has always been fascinating. It gives us hope of finding something new. Humans have always been explorers. When people from old times didn’t know about unknown lands they were compelled to explore them. The idea of space exploration has a sense of mystery and excitement about it. We have achieved some of the goals but not all. Through our space probes we were able to find new planets stars and even galaxies. Space exploration should continue because it could help solve many problems

Fair February 21‚ 2013 Where do planets come from? Abstract Astronomers have spent many centuries wondering how our solar system and its planets came to be. We could only see the end result of planet formation‚ not the process itself. And we had no other examples to study. Even with the knowledge gained about other solar system‚ we were left to wonder‚ are there other planetary systems out there‚ and did they form like ours? This project leads you to find out how mighty planets are formed from cosmic

As we know that our solar system has a total of eight planets‚ after they decided Pluto wasn’t a planet it was then know to be a dwarf planet. What if there are other planets in our solar system? With advanced technology they did it‚ they found another planet that’s in our solar system‚ but it’s not proven yet. The high tech computers detect a planet but it has still not been seen by the human eye. So what this means is the the planet isn’t officially a planet until it has been seen by a human for

Four major features provide clues: (1) The Sun‚ planets‚ and large moons generally rotate and orbit in a very organized way. (2) With the exception of Pluto‚ the planets divide clearly into two groups: terrestrial and jovian. (3) The solar system contains huge numbers of asteroids and comets. (4) There are some notable exceptions to

Life on Other Planets Life on other planets‚ Is there another titan planet out there that harbors life? Scientist have found two such planets in a neighboring but distant Solar System. Which planets are habitable and is there already life there or basically in general‚ “Is there life in outer space?” That is the question and debate among astrologists and scientist alike about this discovery of two planets that orbit the red dwarf star of Gliese 581 (Gliese 581c.eu). The fascination of intelligent

Measures of Astronomical Distances • Let’s view the Universe in terms of kilometres – The size of the observable universe is roughly 130‚000‚000‚000‚000‚000‚000‚000 km ! - Obviously measuring astronomical distances in km is inconvenient. - We need much BIGGER units of distance: • Some commonly used distance units: 1 ly (light year) = Distance traveled by light in 1 year = 9.46 trillion km 1 AU (astronomical unit) = average distance between the Sun & Earth = 150 million km A unit of distance‚

There are seven possible scenarios which scientists believe if occur‚ could naturally end this planet and humanity‚ the world as we know it. Orbital change‚ rotational change‚ collisions with the Earth‚ the big rip‚ the sun‚ black holes‚ and other systems going out of whack can cause events that could potentially cause an end to life on Earth. People have theorized about an end to the planet or people on it for most of time. However‚ the scenarios that will be explained are the most logical and probable
