Our solar system

  We call it the solar system because it is made up of our star, the Sun, and everything bound to it by gravity. The solar system has one star, eight planets, five officially named  dwarf planets ,  hundreds of moons, thousands of comets, and more than a million asteroids. Our solar system is located in the Milky Way, a barred spiral galaxy with two major arms, and two minor arms. Our Sun is in a small, partial arm of the Milky Way called the Orion Arm, or Orion Spur, between the Sagittarius and Perseus arms. Our solar system orbits the center of the galaxy at about 515,000 mph (828,000 kph). It takes about 230 million years to complete one orbit around the galactic center. Planets following Sun in nearer to farther order Mercury, Venus, Earth, Mars, Jupiter, Uranus, Neptune SUN : The Sun center of our solar system is a huge glowing sphere of hot gas. Most of this gas is hydrogen (about 70%) and helium (about 28%). Carbon, nitrogen and oxygen make up 1.5% and the oth...

Planet rotation and types of rains in planets and its natural sattilities

 Planets in our solar system to rotate clock wise is Venus and Uranus. All other planets rotate anti-clock wise. A  planet  is a large,  rounded   astronomical body  that is generally required to be in  orbit  around a  star ,  stellar remnant , or  brown dwarf , and is not one itself. [ 1 ]  The  Solar System  has eight planets by the most restrictive definition of the term: the  terrestrial planets   Mercury ,  Venus ,  Earth , and  Mars , and the  giant planets   Jupiter ,  Saturn ,  Uranus , and  Neptune . The best available theory of planet formation is the  nebular hypothesis . Sun :  Sun do not rotate. When you think of a day, you normally think of one cycle through one day and one night. That is called a solar day. Another way to measure a day is to count the amount of time it takes for a planet to completely spin around and make one full rotation. Th...
