Project Description

Keeping an Eye on Space Rocks

JPL manages NASA’s Center for Near-Earth Object Studies, which tracks comets and asteroids that pass close to Earth’s orbital neighborhood.

A Near-Earth Object (NEO) is generally defined as an asteroid or comet that approaches our planet less than 1.3 times the distance from Earth to the Sun (the Earth-Sun distance is about 93 million miles). Most NEOs pose no peril at all. It’s the small percentage of Potentially Hazardous Asteroids that draws extra scrutiny. These objects are defined as those that approach Earth at less than half the Earth-Sun distance.

Scientists and engineers are developing plans for warning systems and diversion tactics, just in case an asteroid should ever be found in an orbit that could endanger our planet.

The following scores were calculated using a statistically-driven machine-learning approach, a type of AI that learns to perform a task by analysing patterns in data. This is an experimental approach to citizen-science impact assessment, and the exact reasoning behind the scores is not explainable. The scores represent a best guess of the impact the project is having in each domain. Scores are recalculated and updated when “View impact report” is clicked.
