The Sun is the star at the center of the Solar System. It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies.
The Sun is the largest object in our solar system. Its diameter is about 865,000 miles (1.4 million kilometers). Its gravity holds the solar system together, keeping everything from the biggest planets to the smallest bits of debris in orbit around it.
Feb 2, 2024 · The sun is an ordinary star, one of about 100 billion in our galaxy, the Milky Way. The sun has extremely important influences on our planet: It drives weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis.
The Sun. The Sun is the star at the heart of our solar system. Its gravity holds the solar system together, keeping everything – from the biggest planets to the smallest bits of debris – in its orbit.
4 days ago · Sun, star around which Earth and the other components of the solar system revolve. It is the dominant body of the system, constituting more than 99 percent of its entire mass. The Sun is the source of an enormous amount of energy, a portion of which provides Earth with the light and heat necessary to support life.
The Sun is the star at the centre of our solar system. It is an almost perfect sphere of super-hot gases whose gravity holds the solar system together. The energy produced by the Sun is essential for life on Earth and is a driving force behind the Earth’s weather.
Jun 13, 2024 · The Sun contains almost ALL of the material in our solar system. 99% of it. All the planets, asteroids and comets add up to less than 1% of the total. The Sun is so far away that it takes light about 8 minutes and 20 seconds for it to get to us – and light is the fastest thing in the universe.
Sep 15, 2018 · Characteristics of the sun. The sun resides some 26,000 light-years from the Milky Way's center, in a tendril of our home galaxy known as the Orion Arm. Every 230 million...
Jun 20, 2024 · The Sun occasionally releases massive amounts of energy, creating solar geomagnetic storms that can interfere with communications and navigation and disrupt the electric power grid. The colorful aurora borealis or Northern Lights and aurora australis or Southern Lights are created by the transfer of energy from solar electrons to molecules in Earth’s upper atmosphere. Those molecules then release that energy in the form of light.
Sep 26, 2019 · The Sun is one of the millions of stars in the solar system. It is, however, larger than most (although not the biggest) and a very special star to us. Without the Sun there would be absolutely no life on Earth. The Sun is 870,000 miles (1.4 million kilometers) across.
