NASA has found that a potentially hazardous asteroid has a 72% chance of hitting Earth, highlighting potential gaps in Earth's preparedness to prevent such an event. The exercise, NASA's fifth biennial Planetary Defense Interagency Tabletop Exercise held in April, was summarized and unveiled on June 20 at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland.
According to an official report by the space agency, NASA conducted the fifth biennial Planetary Defense Interagency Tabletop Exercise in April. On June 20, NASA unveiled the summary of the exercise, held at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland.
The tabletop exercise, apart from NASA, included nearly 100 representatives from various US government agencies and international collaborators.
While there are no known significant asteroid threats in the foreseeable future, this was done to assess the Earth's ability to respond effectively to the threat of a potentially hazardous asteroid.
NASA maintains a dashboard that tracks asteroids and comets making relatively close approaches to Earth. The dashboard displays the date of the closest approach, approximate object diameter, relative size, and distance from Earth for each encounter. It tracks asteroids within 7.5 million kilometres of Earth.
