The star’s origins as a symbol of communist mass movements dates from the time of the Bolshevik Revolution and the Russian Civil War, but the precise first use remains unknown. On the other hand one account of the symbol’s origin traces its roots to the Moscow troop garrison toward the end of World War I. At this time, many troops were fleeing from the Austrian and German fronts, joining the local Moscow garrison upon their arrival in the city. To distinguish the Moscow troops from the influx of retreating front-liners, officers gave out tin stars to the Moscow garrison soldiers to wear on their hats. When those troops joined the Red Army and the Bolsheviks they painted their tin stars red, the color of socialism, thus creating the original red star.
However, the astronomers will require more HST observations in order to obtain accurate measurements in order to determine if the moon's orbit is circular or elliptical. Preliminary estimates suggest that if the moon is in a circular orbit, it finishes a circle around Makemake in 12 days or longer.
For those craters smaller than 30 kilometers in diameter, he discovered impacts both increased and decreased porosity in the upper layer of the lunar crust.
Dr. Thomas and his team at Cornell University have tried to peer into the mysterious interior of the weird little Space egg that is Methone. They started out with the hypothesis that Saturn's relentless strong gravity pulls the little moon into an elongated shape, just like Earth's own large Moon raises ocean tides on our own planet. Then the team went on to calculate how dense the little moon would have to be for its own gravity to counteract those intense tidal forces and create its strange egg-shape.
