NASA’s Juno Spacecraft will arrive at Jupiter in the next few day after nearly five years in Space. While it’s purpose is primarily to study Jupiter’s origins, interior structure, deep atmosphere and magnetosphere it’s worth remembering Jupiter is also host to the largest and some of the most interesting moons in the solar system. Lets […]

http://on.fb.me/1DjdWGYI like Star Wars, Star Wars is set in space, my website is about space, hence I made a Star Wars thing for the website. The graphic shows all the planets and moons seen in the original (theatrical) trilogy to scale alongside the two Death Stars for good measure. The sizes of the various bodies […]

http://on.fb.me/1DjdWGYAn orbit is the path an object takes in space as it revolves around another object. While a planet travels in one direction, it is also affected by the Sun’s gravity causing it to take a curved route that eventually brings it back to its starting point. This complete revolution equates to a single orbit. […]

http://on.fb.me/1DjdWGYTitan is the largest moon in the Saturnian system and the second-largest moon in the solar system. If it were not orbiting Saturn, it might be considered a planet in its own right. It is covered with a thick atmosphere that some consider to be similar to that of early Earth. Moon Profile Diameter: 5,150 […]

http://on.fb.me/1DjdWGYExoplanets, also called “extrasolar planets” are worlds orbiting other stars. Thousands of possible exoplanets have been found through ground-based and space-based observatories. Nearly 2,000 have been confirmed; the rest are awaiting further observations so that astronomers can be sure that they are planets. Astronomers estimate that there could be trillions of planets around other stars. Facts […]
