Facts about Solar

solar system definition. The region of the universe near the sun that includes the sun, the nine known major planets and their moons or satellites, and objects such as asteroids and comets that travel in independent orbits.

The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, and dust and gas. Everything in the Solar System orbits or revolves around the Sun.

The Solar System is the Sun and all the objects that orbit around it. The Sun is orbited by planets, asteroids, comets and other things. ... There are eight planets in the Solar System. From closest to farthest from the Sun, they are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

Galileo Galilei was the first to discover physical details about the individual bodies of the Solar System. He discovered that the Moon was cratered, that the Sun was marked with sunspots, and that Jupiter had four satellites in orbit around it.

The solar system is a group of planets or celestial bodies that revolve around a sun. An example of the solar system is the eight planets including Earth that revolve around the sun.

They wonder how many solar systems are in our galaxy. ... For many years scientists have studied our own solar system. But until the last few years, we knew of no other solar systems. This may seem surprising, as the Sun is one of about 200 billion stars (or perhaps more) just in the Milky Way galaxy alone.

This definition, which applies only to the Solar System, states that a planet is a body that orbits the Sun, is massive enough for its own gravity to make it round, and has "cleared its neighbourhood" of smaller objects around its orbit.

Solar power systems derive clean, pure energy from the sun. Installing solar panels on your home helps combat greenhouse gas emissions and reduces our collective dependence on fossil fuel. Traditional electricity is sourced from fossil fuels such as coal and natural gas.

Solar energy is, simply, energy provided by the sun. This energy is in the form of solar radiation, which makes the production of solar electricity possible. Electricity can be produced directly from photovoltaic, PV, cells. (Photovoltaic literally means “light” and “electric.”)

The history of photovoltaic energy (aka. solar cells) started way back in 1876. William Grylls Adams along with a student of his, Richard Day, discovered that when selenium was exposed to light, it produced electricity.

Solar energy is used today in a number of ways:As heat for making hot water, heating buildings, and cooking.To generate electricity with solar cells or heat engines.To take the salt away from sea water.To use sun rays for drying clothes and towels.It is used by plants for the process of photosynthesis.

Solar-powered photovoltaic (PV) panels convert the sun's rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. This electricity can then be used to supply renewable energy to your home or business.

Advantages of Solar EnergyRenewable Energy Source. Among all the benefits of solar panels, the most important thing is that solar energy is a truly renewable energy source. ... Reduces Electricity Bills. ... Diverse Applications. ... Low Maintenance Costs. ... Technology Development. ... Cost. ... Weather Dependent. ... Solar Energy Storage Is Expensive.More items...

Disadvantages of Solar Energy. ... It is energy derived from the sun. Renewable energy technologies such as solar cells and solar panels are used to harness the sun's energy to provide light, heat, hot water and generation of electricity for homes, businesses, and industries.

The potential environmental impacts associated with solar power — land use and habitat loss, water use, and the use of hazardous materials in manufacturing — can vary greatly depending on the technology, which includes two broad categories: photovoltaic (PV) solar cells or concentrating solar thermal plants (CSP).Mar 5, 2013

Solar panels installed on your roof work best during daylight hours. When the sun is shining directly onto them, sunlight can be converted into electricity. Your solar panel efficiency drops at night because there is no sunlight to convert to electricity and solar panels can't generate power in darkness.

Solar energy can have a positive, indirect effect on the environment when using solar energy replaces or reduces the use of other energy sources that have larger effects on the environment. However, some toxic materials and chemicals are used to make the photovoltaic (PV) cells that convert sunlight into electricity.Aug 31, 2017

Venus is the second planet from the sun and has a temperature that is maintained at 462 degrees Celsius, no matter where you go on the planet. It is the hottest planet in the solar system. So what makes Venus hotter than Mercury? Mercury doesn't have any atmosphere, and atmosphere can hold and trap heat.

Our solar system is made up of a star that we call the Sun , along with eight or nine planets (more on that later): Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and the most controversial: Pluto. The solar system also includes the satellites of these planets, numerous comets, asteroids, and meteoroids.

Scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust.

The Solar System. Our solar system consists of an average star we call the Sun, the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. It includes: the satellites of the planets; numerous comets, asteroids, and meteoroids; and the interplanetary medium.

The Solar System is the Sun and all the objects that orbit around it. The Sun is orbited by planets, asteroids, comets and other things. It is billions of years old. The Sun is a star. ... The first four planets are called terrestrial planets.
