NASA heliophysicist Alex Young explains how this simple sound connects us with the Sun and all the other stars in the universe. Its gravity holds the solar system together, keeping everything from the biggest planets to the smallest particles of debris in its orbit. The sun keeps our planet warm enough for living things to thrive.
Sunspots and Solar Flares.
Main Sequence Stars. In Depth Overview. The Sun actually is a star and it really is pretty much an average one, just one of about 200 billion stars in the Milky Way galaxy. Our Sun will stay in this mature phase (on the main sequence as shown in the Hertzsprung-Russell Diagram) for approximately 10 billion years. Make a Star Finder. Our Solar System. The Sun actually is a star and it really is pretty much an average one, just one of about 200 billion stars in the Milky Way galaxy.

What happens when stars and planets align?
The individual lessons contain work sheets to give on-going feedback on student comprehension. Our Sun is an average sized star: there are smaller stars and larger stars, even up to 100 times larger. Stars are fueled by the nuclear fusion of hydrogen to form helium deep in their interiors. The Sun actually is a star and it really is pretty much an average one, just one of about 200 billion stars in the Milky Way galaxy. But it is a special star for those of you who live on Earth, because you are so close to it that it appears extremely bright. The Latest Why ESA and NASA's SOHO Spacecraft Spots So Many Comets. If another object is nearby, it is pulled into the curve.
The hottest stars may be almost 100,000 (100 thousand) degrees Fahrenheit. Objects with more mass have more gravity.
NASA.gov brings you the latest news, images and videos from America's space agency, pioneering the future in space exploration, scientific discovery and aeronautics research.
What Is a Supernova? The Sun — the heart of our solar system — is a yellow dwarf star, a hot ball of glowing gases.
Its gravity holds the solar system together, keeping everything – from the biggest planets to the smallest particles of debris – in its orbit. It gives us light so we can see. Dr. Marc answers questions about the Sun. Learn about what makes our Sun a very busy place!
How Hot Can a Star Be? What Is a Solar Eclipse? But it is a special star for those of you who live on Earth, because you are so close to it that it appears extremely bright. Full moons, eclipses and new planet discoveries, to name a few. NASA.gov brings you the latest images, videos and news from America's space agency.
Overview Quick Take. Gravity also gets weaker with distance. What causes these burns? We provide the data, graphics, images and research to … A star the size of our Sun requires about 50 million years to mature from the beginning of the collapse to adulthood.
Make sun paper! Quick Take .

Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet. Our Star: The Sun (Grades 1-3) This is a unit on the Sun that includes a step-by-step investigation for the younger student to understand our place in the solar system, using relative size and scaling, rotation and revolution and a number of assessment tools. The Sun is a yellow dwarf star, a hot ball of glowing gases at the heart of our solar system. That big number means the stars are far, far hotter than anything you have ever seen or felt here on Earth.
Our Sun is 864,000 miles in diameter and 10,000 degrees Fahrenheit on the surface. Our special star teaches us about all stars.
