The definition of planet since the word was coined by the ancient greeks has included within its scope a wide range of celestial bodies.

Definition of solar system wikipedia. Some of the larger small solar system bodies may be reclassified in future as dwarf planets pending further examination to determine whether or not they are in hydrostatic equilibrium. The solar system formed 46 billion years ago from the gravitational collapse of a giant. The sun is a star.

Solar power is the conversion of energy from sunlight into electricity either directly using photovoltaics pv indirectly using concentrated solar power or a combination. It is billions of years old. According to this definition there are eight known planets in the solar system.

A photovoltaic system also pv system or solar power system is a power system designed to supply usable solar power by means of photovoltaics. The definition distinguishes planets from smaller bodies and is not applicable outside the solar system. To date there is no accepted definition of extrasolar planets or exoplanets.

The orbits of natural satellites are not centered on the sun but around other solar system objects such as planets dwarf planets and small solar system bodies. This means that it has strong gravity. Greek astronomers employed the term asteres planetai asteres plantai wandering stars for star like objects which apparently moved over the sky.

Under this definition the solar system is considered to have eight planets. The solar system is the sun and all the objects that orbit around it. The solar system is the gravitationally bound system of the sun and the objects that orbit it either directly or indirectly.

It contains 999 percent of the solar systems mass. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Bodies that fulfill the first two conditions but not the third such as ceres pluto and eris are classified as dwarf planets provided they are not also natural satellites of other planets.

It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. The sun is orbited by planets asteroids comets and other things. Of the objects that orbit the sun directly the largest are the eight planets with the remainder being smaller objects the dwarf planets and small solar system bodies.

Solar system definition the sun together with all the planets and other bodies that revolve around it. Solar energy is radiant light and heat from the sun that is harnessed using a range of ever evolving technologies such as solar heating photovoltaics solar thermal energy solar architecture molten salt power plants and artificial photosynthesis.
