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.
Sep 26, 2019 · January 4, 2021. Our Sun is a normal main-sequence G2 star, one of more than 100 billion stars in our galaxy. The Sun Profile. diameter: 1,390,000 km. mass: 1.989e30 kg. temperature: 5800 K (surface) 15,600,000 K (core) History of The Sun. The Sun is by far the largest object in the solar system.
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. Without the sun’s heat and light, life on Earth would not exist.
10 things. The Sun is about 100 times wider than Earth and about 10 times wider than Jupiter, the biggest planet. The Sun is the only star in our solar system. It is the center of our solar system, and its gravity holds the solar system together.
2 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. 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.
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.
Meet the Sun. The Sun is a yellow dwarf star at the center of our solar system. Earth and all other objects in our solar system orbit around the Sun due to gravity – the Sun contains over 98% of all mass in the solar system and so exerts a strong gravitational pull.
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 years, the sun—and the...
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. Facts about the Sun.
