The sun is the real star of the show—literally! The closest star to Earth, it’s the source of all the heat and light that makes flowers bloom, songbirds croon, and sunbathers swoon. Life wouldn’t exist without it. It's also the center of our solar system and by far its largest object. More than a million Earths would fit inside the sun!

Life on Earth depends on the Sun. Here are just a few reasons why: 1. The Sun’s gravity holds our entire solar system together. Our solar system is even named after the Sun (the Latin word for Sun is “sol”). 2. Heat from the Sun makes Earth warm enough to live on. 3. Without light from the Sun, there would be no plants or animals—and, therefore, no...
In our solar system, the closest planet to the Sun is Mercury. Our Sun’s closest star neighbor is called Proxima Centauri. It is approximately 4 light-yearsaway.
First of all, you should never look directly at the Sun without very special protective eyewear. But NASA has many great pictures of the Sunfor you to look at! Scientists use telescopes with filters to capture images of the Sun. These images help us learn about our star. The photo below was taken by a NASA spacecraft called the Solar Dynamics Obser...
A spacecraft would easily burn up if it tried to fly into the Sun. However, NASA’s Parker Solar Probe is flying closer than any other robotic explorer ever has. It will be flying inside the Sun’s atmosphere, or corona. This spacecraft will help us learn more about how the Sun works and how solar activitystarts. This helps us to be more prepared!
It is a nearly perfect sphere of hot plasma, essentially, a hot ball of glowing gases. It is the most important source of energy for life on Earth. The Sun has a diameter of around 1.39 million kilometers / 864,000 miles. This is 109 times greater than the diameter of our planet.
May 6, 2024 · All About the Sun! Can you see any stars during the daytime? Of course! 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.
- The sun is a 4.5-billion-year-old star. That’s right, we’ve got a giant ball of helium and hydrogen at the center of our solar system!
- The sun is about 93 million miles from Earth. Or 150 million kilometers, but who’s counting? It might be far away, but it does so much to support our lives here on this planet!
- It’s the largest object in our solar system. In terms of volume, it would take 1.3 million Earths to fill the sun. That’s crazy!
- The sun’s gravity holds the solar system together. Whether it’s fragments of debris or massive planets, it keeps everything orbiting around it.
Oct 16, 2023 · The Sun is the star in the center of our solar system. It is a yellow dwarf star. It gives off energy as light. That includes light, infra-red energy (heat), ultraviolet light and radio waves. It also gives off a stream of particles, which reaches Earth as "solar wind". The source of all this energy is nuclear fusion.
