TopDir is a human edited web directory with various categories. Our mission is to organize theme based websites and remove the clutter from the information. We strive to provide context based website results to our visitors. This directory is an evolving one and we regularly add new categories, if there is a necessity. Members can suggest new categories and websites for inclusion. This is one stop promotion site for webmasters and website owners. We invite you to browse the categories and suggest your website url for an editor review. This page is focused on one particular aspect of Science, Astronomy, Solar System.

Help build the largest human-edited directory on the web. Soumettre un site - Open Directory Project - Devenir Editeur


Web directories list the websites by theme. The links in a web directory are collected, edited and organized by humans. Yahoo and Dmoz ODP(Open Directory Project) are considered as the best human-edited web directories on the Internet and they are one of the most trusted and relied traffic sources. Since these directories get thousands of submissions every day, it is sometimes difficult to get listed in them and your URL may take a long time to be reviewed and listed. Generally good directory listings give a surprise boost to your link popularity.
