If you were modeling only heliocentric orbits or those about other planets‚ you could change the central body for the scenario by making sure that “Planetary Options” is checked on the View menu at

Deep Space Probes 1 Have you ever considered life on other planets‚ or maybe galaxies that we have never heard of? Thanks to space probes these dreams may become a reality sooner than u think. In 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

Trappist system helps build upon the fact of we are not alone in the universe. Trappist-1 includes a sun slightly larger than jupiter and seven orbiting planets‚ Most planets have sizes and masses comparable to the earth‚ and the size of the system is from mercury to mars. Trappist is located about 39 light-years away. It’s speculated that The planets of trappist are such a short distance away‚ debri could hit the another one of the planets.Though the processes of panspermia‚ any

Why We Should Send a Manned Mission to Mars Nowaday the topic in discussion is if it is posible to live in Mars because scientists will demostrate that Mars has similar qualities to our planet‚ or it is possible to find a new kind of life that helps us to improve our technology. Also‚ differnt countries like U.S.‚ China‚ Russia and European Union are interested in spends and takes risk to send a special mission to Mars in order to find evidence that proves their theories.

Astronomy. September‚ 2012. The article I’m writing about is about the NASA Curiosity Rover and how it’s doing on its trip to mars. The reason that NASA has sent this rover is to find potential signs of life on the surface of mars. They are trying to find evidence that there once has been enough resources to have any kind of life on mars. NASA has sent a rover to Mars called the Curiosity Rover. It is on its way to the slope of Mount Sharp in Gale Crater which is the rovers’ destination. On the

SOLAR SYSTEM PLANETS MERCURY • The closest planet to the sun‚ Mercury is only a bit larger than Earth’s moon. Its day side is scorched by the sun and can reach 840 degrees Fahrenheit (450 Celsius)‚ but on the night side‚ temperatures drop to hundreds of degrees below freezing. VENUS • The second planet from the sun‚ Venus is terribly hot‚ even hotter than Mercury. The atmosphere is toxic. The pressure at the surface would crush and kill you. Scientists describe Venus’ situation as a runaway greenhouse

billion years ago. Different Theories and Hypothesis Fission Theory One theory is that the moon must have broken away from Earth‚ when the earth was still a rotating ball of molten rock. Earth might have been spinning so fast that part of our planet separated into space‚ this could be why our chemical composition is similar to the moon. Fission theorist stated that the Pacific ocean might have been the place where the moon material broke off. Capture Theory This theory says that the moon was

helped show that the variations in color on the surface of the planet Mars were not caused by the presence of life. Earlier observers of Mars had suggested that the dark‚ greenish areas might be vegetation of some sort. Sagan proposed that the dark areas were hills‚ which the Martian wind stripped of the finer‚ lighter-colored dust particles that collected in the valleys. Sagan’s theory was confirmed by the Mariner 9 spacecraft’s visit to Mars. During the 1970s Sagan studied the present atmosphere
