SOLAR SYSTEM Our planetary system is located in an outer spiral arm of the Milky Way galaxy. Our solar system consists of our star, the Sun, and everything bound to it by gravity — the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, dwarf planets such as Pluto, dozens of moons and millions of asteroids, comets and meteoroids. Beyond our own solar system, we have discovered thousands of planetary systems orbiting other stars in the Milky Way. Beyond our own solar system, there are more planets than stars in night sky. So far, we have discovered thousands of planetary systems orbiting other stars in the Milky Way, with more planets being found all the time. Most of the hundreds of billions of stars in our galaxy are thought to have planets of their own, and the Milky Way is but one of perhaps 100 billion galaxies in the universe. While our planet is in some ways a mere speck in the vast cosmos, we have a lot of company out there. It seems that we live i...

 BIG BANG   Most astronomers believe the Universe began in a Big Bang about 14 billion years ago. At that time, the entire Universe was inside a bubble that was thousands of times smaller than a pinhead. It was hotter and denser than anything we can imagine. Then it suddenly exploded. The Universe that we know was born. Time, space and matter all began with the Big Bang. In a fraction of a second, the Universe grew from smaller than a single atom to bigger than a galaxy. And it kept on growing at a fantastic rate. It is still expanding today. As the Universe expanded and cooled, energy changed into particles of matter and antimatter. These two opposite types of particles largely destroyed each other. But some matter survived. More stable particles called protons and neutrons started to form when the Universe was one second old. Over the next three minutes, the temperature dropped below 1 billion degrees Celsius. It was now cool enough for the protons and neutrons to ...

The Moon is Earth's only natural satellite. At about one-quarter the diameter of Earth, it is the largest natural satellite in the Solar System relative to the size of its planet, the fifth largest satellite in the Solar System overall, and is larger than any known dwarf planet. Gravity :  1.62 m/s² Distance to Earth :  384,400 km Radius :  1,737.4 km Orbital period :  27 days Surface area :  3.793×10 7  km 2 ; (0.074 of Earth's) Surface pressure :  10 −7  Pa (1 picobar) (day); 10 −10  Pa (1 femtobar); (night);

  Internet , a system architecture that has revolutionized communications and methods of commerce by allowing various   computer networks   around the world to interconnect. Sometimes referred to as a “network of networks,” the Internet emerged in the United States in the 1970s but did not become visible to the general public until the early 1990s. By 2020, approximately 4.5 billion people, or more than half of the world’s population, were estimated to have access to the Internet. The Internet provides a capability so powerful and general that it can be used for almost any purpose that depends on information, and it is accessible by every individual who connects to one of its  constituent  networks. It supports human communication via social media,  electronic mail  (e-mail), “chat rooms,” newsgroups, and audio and video transmission and allows people to work collaboratively at many different locations. It supports access to digital information by many...

  The Internet is a vast network that connects  computers  all over the world. Through the Internet, people can share information and communicate from anywhere with an Internet connection.

  Compound interest   is the addition of   interest   to the   principal sum   of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest. Compound interest is standard in   finance   and   economics . Compound interest is contrasted with  simple interest , where previously accumulated interest is not added to the principal amount of the current period, so there is no compounding. The  simple annual interest rate  is the interest amount per period, multiplied by the number of periods per year. The simple annual interest rate is also known as the  nominal interest rate  (not to be confused with  the interest rate not adjusted for inflation , which goes by the same name). A= P ( 1+R/100)n
