Solar System About 4‚700 million years ago‚ the Solar System was just a spinning disc of dust and gas. The dust began to collect together and our Sun formed at the centre. Around Sun‚ lumps of rock joined up to form smaller bodies and‚ like the Sun‚ they heated up. But because they were smaller they soon cooled down and became planets. Sun accounts for 99.85 per cent of mass of the solar system. About 1.3 billion earths would fit inside the sun. The solar system consists of the Sun; the nine planets

developed by combining the models of established solar module and DC-DC buck-boost converter with the algorithms of perturbation and observation (P&O)‚ incremental conductance (INC) and hill climbing (HC)‚ respectively. The system is simulated under different climate conditions and MPPT algorithms. According to the comparisons of the simulation results‚ it can be observed that the photovoltaic simulation system can track the maximum power accurately using the three MPPT algorithms discussed in this paper

Solar power: In fact‚ every minute‚ enough energy arrives at the Earth to meet our demands for a whole year - if only we could harness it properly. The Delhi Metro came to a standstill yet again on Tuesday afternoon after services were suspended for two hours due to collapse of the Northern Power Grid for the second consecutive day‚ causing inconvenience to commuters. As the power grid collapsed at around 1 pm‚ Delhi Metro trains stopped on tracks‚ some inside tunnels‚ due to no supply of power

growth‚ energy needs are increasing day by day throughout the world. At the same time fossil fuels are depleting and lots of environmental issues are coming into picture for addition of any more fossil fuel based power plants. So many countries in the world including Asia Pacific region have placed emphasis on the development of renewable sources of energy in order to reduce fossil fuel consumption and decrease pollution. In the quest for a greener planet and renewable energy sources‚ solar energy is

SOLAR SYSTEM PLANETS MERCURY • The closest planet to the sun‚ Mercury is only a bit larger than Earth’s moon. Its day side is scorched by the sun and can reach 840 degrees Fahrenheit (450 Celsius)‚ but on the night side‚ temperatures drop to hundreds of degrees below freezing. VENUS • The second planet from the sun‚ Venus is terribly hot‚ even hotter than Mercury. The atmosphere is toxic. The pressure at the surface would crush and kill you. Scientists describe Venus’ situation as a runaway greenhouse

1. Our solar system is made up of the sun and everything that travels around it. This includes eight planets and their natural satellites such as Earth’s moon; dwarf planets such as Pluto and Ceres; asteroids; comets and meteoroids 2. The sun is the center of our solar system. It contains almost all of the mass in our solar system and exerts a tremendous gravitational pull on planets and other bodies. 3. Our solar system formed about 4.6 billion years ago. 4.
