ECHO EARTH / Asteroids & Comets
Asteroids & Comets
Discover small bodies with their uncertainty intact.
Near and far objects
ECHO EARTH includes an asteroid and comet catalogue with tools to inspect selected objects. The space scene can display objects beyond the near-Earth subset; not every catalogue entry has a precise, current, visually resolved position.
Understanding orbital models
Published elements from providers such as NASA/JPL can support modeled orbital paths. A computed trajectory, close-approach prediction and actual observation are different categories of information. Distances and validity periods matter.
Explore Apophis
Apophis is an example of the named objects accessible through the small-body catalogue. Use the interactive explorer to examine available details and their source rather than treating a visualized trajectory as an impact forecast.
