The places covered are listed online on the CAMS website, and the research team particularly needs more coverage triangulating meteor showers in the Southern Hemisphere. Jenniskens hopes that the visualization will inspire more amateur astronomers to participate in the surveillance studies. Some showers don't wander, Jenniskens added - and whether and how a meteor shower wanders holds clues to how old the stream is and how it was created. In all, 18 short-period and 27 longer-period showers wander from night to night (and there are more to be discovered in the Southern hemisphere, Jenniskens said).

During their peak, the Perseids appear to emanate from the constellation Perseus, but the meteor shower's source wanders slightly as well near the beginning and end of the shower (even when Earth's movement is taken into account). Longer-period meteor showers whose orbits venture further out show some change, too, even though their orbits are less perturbed by Jupiter - such as the famous Perseid meteor shower, which is generated by the debris strewn behind Comet Swift-Tuttle. Those effects in combination mean the stream takes on a skewed shape and the meteor shower moves across the sky, and also that Earth stays within the stream longer. The spots where these objects' orbits cut through the plane of the planets change over time, and the pull of Jupiter at the outer end of their orbits changes their closest approach to the sun, too. The effect likely comes from the tug of planets on the objects creating the streams, Jenniskens said. Those streams are stretched and warped so the meteor showers' radiants move dramatically across the sky over the few months' duration of each shower. Some of the most extreme changes came from short-period meteor showers such as the Kappa Cygnids and the Omicron Eridanids, whose objects have relatively short orbits that loop past Earth and out near Jupiter.

Eyes gathers its data from JPL’s Solar System Dynamics database, which provides real-time data for the orbits, characteristics, and discovery of most known natural bodies (including NEOs) in our solar system. “The headlines often depict these close approaches as ‘dangerously’ close, but users will see by using Eyes just how distant most of these encounters really are.”Įyes on Asteroids was developed with support from NASA’s Planetary Defense Coordination Office at the agency’s headquarters in Washington and from JPL’s Center for Near-Earth Object Studies. “We were keen to include this feature, as asteroid close approaches often generate a lot of interest,” said Craig. While you’re on the topic, choose the “Asteroid Watch” tab to see the next five asteroid close approaches. Just select “Learn” for details on topics like asteroid close approaches to Earth or to fly along with the dramatic close approach of asteroid Apophis on April 13, 2029. There’s also plenty of detail on the fascinating science behind NEOs and the importance of tracking potentially hazardous objects. “Every NEO can be found inside the app, as can most of the spacecraft that have visited these objects.” “We wanted Eyes on Asteroids to be as user-friendly as possible while telling the stories about humanity’s exploration of these fascinating objects,” said Jason Craig, technical producer of the Visualization Technology Applications and Development team at NASA’s Jet Propulsion Laboratory in Southern California, which developed Eyes. The visualization receives twice-daily updates with the latest data, so as soon as a new object is discovered and its orbit is calculated, it’s added to the app. Using the slider at the bottom of the screen, you can travel quickly forward and backward through time to see their orbital motions. The new web-based app depicts the orbits of every known NEO, providing detailed information on those objects.

Now totaling about 28,000, their numbers rising daily, these objects are tracked carefully by NASA-funded astronomers in case any might pose an impact threat to our planet. Thousands of asteroids and dozens of comets are discovered every single year, some of which – called near-Earth objects (NEOs) – follow orbits that pass through the inner solar system. NASA’s Eyes on Asteroids brings this data to any smartphone, tablet, or computer with an internet connection – no download required. Through a new 3D real-time visualization tool, you can now explore the asteroids and comets that approach Earth’s orbital neighborhood – and the spacecraft that visit these objects – with a click or a swipe.
