About Wikipedia

This is the front page of the Simple English Wikipedia. Wikipedias are places where people work together to write encyclopedias in different languages. We use Simple English words and grammar here. The Simple English Wikipedia is for everyone, such as children and adults who are learning English. There are 260,787 articles on the Simple English Wikipedia. All of the pages are free to use. They have all been published under both the Creative Commons Attribution/Share-Alike License 4.0 International License and the GNU Free Documentation License. You can help here! You may change these pages and make new pages. Read the help pages and other good pages to learn how to write pages here. If you need help, you may ask questions at Simple talk.

When writing articles here:

Use Basic English words and shorter sentences. This allows people to understand complex terms or phrases.
Write good pages. The best encyclopedia pages have useful, well-written information.
Use the pages to learn and teach. These pages can help people learn English. You can also use them to make a new Wikipedia to help other people.
Simple does not mean short. Writing in Simple English means that simple words are used. It does not mean readers want basic information. Articles do not have to be short to be simple; expand articles, add details, but use basic vocabulary.
Be bold! Your article does not have to be perfect, because other editors will fix it and make it better. And most importantly, do not be afraid to start and make articles better yourself.

Selected article

Jupiter is the largest planet in the Solar System. It is the fifth planet from the Sun. Jupiter is classified as a gas giant. This is because it is very big and made up of gas. The other gas giants are Saturn, Uranus and Neptune. Jupiter has a mass of 1.8986×10²⁷ kg or about 318 Earths. This is twice the mass of all the other planets in the Solar System put together.

Jupiter was known to the ancient Romans. They named it for the Roman god Jupiter. Jupiter is the third brightest object in the night sky. Only the Earth's moon and Venus are brighter. Jupiter has at least 95 moons. 75 of these moons are very small at less than 5 km wide. The four main moons are Io, Europa, Ganymede and Callisto. These moons are the largest. These four are called the Galilean moons. They are called this because they were discovered by the Italian astronomer Galileo Galilei. Ganymede is the largest moon in the Solar System.
