Características. El Sol es una estrella de tipo-G de la secuencia principal que abarca aproximadamente el 99,86 % de la masa del sistema solar. Éste tiene una magnitud absoluta de +4,83, estimada como más brillante que el 85 % de las estrellas de la Vía Láctea, la mayoría de las cuales son enanas rojas.Pertenece a la Población I, o a las estrellas ricas en elementos pesados.
The Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It’s about 93 million miles (150 million kilometers) from Earth and it’s our solar system’s only star. Without the Sun’s energy, life as we know it could not exist on our home planet.
Hace 6 días · The Sun wields a huge influence on Earth. Its gravity holds our planet in its orbit, and solar energy drives the seasons, ocean currents, weather, climate, radiation belts, and auroras on Earth. The solar wind, a flow of charged particles from the Sun, constantly bombards Earth’s magnetosphere, a vast magnetic shield around the planet.
The Sun is the engine behind much of Earth’s environment, providing energy for everything from ocean currents and weather patterns to the plants and algae that form the base of many food chains. The Sun is the easiest star for us to study, making it very useful to the field of astrophysics.
The Sun is our nearest star. Nuclear reactions deep within create energy in the form of the light and heat that we need to survive. To generate this energy, the Sun consumes four million tonnes of hydrogen fuel every second, and has done so since it was born, around 4.6 billion years ago.
15 de sept. de 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 years, the sun—and the...
13 de jun. de 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.
13 de jun. de 2024 · The light of daytime comes from our closest star: the Sun. Even though our Sun is kind of an ordinary star, there are a few things that make our Sun quite special. Make Sun paper! Answer your questions: What is a solar eclipse? What causes the seasons? What is space weather? Where does the Sun's energy come from?
18 de jun. de 2024 · The hyperactive sunspot region responsible for the beautiful auroras earlier in May was still alive and kicking when it rotated away from Earth’s view. Watching from the other side of the Sun, the ESA-led Solar Orbiter mission detected this same region producing the largest solar flare of this solar cycle. By observing the Sun from all sides, ESA missions reveal how active sunspot regions ...
5 de ene. de 2018 · The sun keeps the planets in its orbit with a tremendous gravitational force. What would happen if it disappeared entirely? Learn about the star at the center of our solar system, and how it is...
