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!
Key Facts & Summary. The Sun is located in the center of the Solar System. 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.
The Sun is one of billions of stars in the Milky Way galaxy. Yet to us here on Earth, it is everything. Without the Sun, we’d have no food, no flowers, no calendars, no weather—and no nasty sunburns.
NASA's Goddard Space Flight Center. Although the Sun is a rather ordinary star, it is very important to the inhabitants of Earth. The Sun is the source of virtually all Earth’s energy. It provides the heat and light that make life on Earth possible. Yet Earth receives only about half a billionth of the energy that leaves the Sun.
