The 'Asteroid Watch' site also contains links for the interested public to sign up for NASA's new asteroid widget and Twitter account.
"Most people have a fascination with near-Earth objects," said Don Yeomans, manager of NASA's Near-Earth Object Program Office at JPL.
"And I have to agree with them. I have studied them for over three decades and I find them to be scientifically fascinating, and a few are potentially hazardous to Earth. The goal of our Web site is to provide the public with the most up-to-date and accurate information on these intriguing objects," he added.
The website provides information on NASA's missions to study comets, asteroids and near-Earth objects, and also provides the basic facts and the very latest in science and research on these objects.
News about near-Earth object discoveries and Earth flybys will be available and made accessible on the site via a downloadable widget and RSS feed.
For those who want to learn about their space rocks on the go, a Twitter feed is offered.
"Asteroid Watch" also contains a link to JPL's more technical Near-Earth Objects Web site, where many scientists and researchers studying near-Earth objects go for information.
"This innovative new Web application gives the public an unprecedented look at what's going on in near-Earth space," said Lindley Johnson, program executive for the Near-Earth Objects Observation program at NASA Headquarters in Washington.
NASA supports surveys that detect and track asteroids and comets passing close to Earth.
The Near-Earth Object Observation Program, commonly called 'Spaceguard', also plots the orbits of these objects to determine if any could be potentially hazardous to our planet.
