Kefir or kephir, alternatively milk kefir, or bÃºlgaros, is a fermented milk drink that originated in the Caucasus Mountains made with kefir grains, a yeast/bacterial fermentation starter. It is prepared by inoculating cow, goat, or sheep milk with kefir grains. Traditional kefir was made in goatskin bags that were hung near a doorway; the bag would be knocked by anyone passing through to help keep the milk and kefir grains well mixed.
Jupiter is composed primarily of gaseous and liquid matter. It is the largest of the four giant planets in the Solar System and hence its largest planet. It has a diameter of 142,984 km (88,846 mi) at its equator. The average density of Jupiter, 1.326 g/cm3, is the second highest of the giant planets, but lower than those of the four terrestrial planets.
Jupiter is the fifth planet from the Sun, and is the largest planet in the solar system. Its average distance from the Sun is 5.2 AU (778,330,000 km), and its equatorial radius is 68,700 km (almost 11 times that of Earth): Though Jupiter is very massive (having 318 times the mass of the Earth), it is not very dense: it has a mean density of 1.4 gm/cm3.
