Nov 26, 2021 · So yes, the Sun is a star. However, not all stars are suns. Using the term sun to refer to any other star is incorrect. Sun is not a synonym for star. So why is it sometimes used as such? The confusion comes most likely from some science fiction movies and books. In those works, the local star or stars are often referred to as “suns”.
From our vantage point on Earth, the Sun may appear like an unchanging source of light and heat in the sky. But the Sun is a dynamic star, constantly changing and sending energy out into space. The science of studying the Sun and its influence throughout the solar system is called heliophysics. The Sun is […]
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 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.
- Our Sun is a star, like the hundreds that you see at night, only much, much closer. The Sun is a huge ball of hot, churning, unpredictable supercharged gasses called plasma.
- The Sun is like an onion: it has layers. Although the Sun doesn’t have a solid surface like Earth, it does have six layers, each one with a different density of plasma.
- The Photosphere. The photosphere is what you see when you look up at the Sun. (Always use “eclipse glasses” to do this!) It’s the visible surface of the Sun, not a solid surface like on planets.
- The Chromosphere. Sandwiched between the visible photosphere and the corona is the gorgeous chromosphere. Wild magnetic fields formed in the photosphere extend out through the chromosphere, creating eruptions and storms, prominences and flares.
The sun is a dynamic star, made of super-hot ionized gas called plasma. The sun’s surface and atmosphere change continually, driven by the magnetic forces generated by this constantly-moving plasma. The sun releases energy in two ways: the usual flow of light that illuminates the Earth and makes life possible; but also in more violent […]

Understanding the sun as a star opens up broader insights into the workings of our universe. The sun’s life-giving heat and light are a result of thermonuclear reactions within its core, a common characteristic of stars. These reactions involve the fusion of hydrogen into helium, releasing vast amounts of energy in the process.
