Prioritized targets

The Didy List is a prioritized list of asteroids that are considered to be the most significant threats to Earth. This prioritization is based on a number of factors, including the asteroid's size, velocity, and distance from Earth. The Didy List is used to help astronomers and planetary defense experts identify and track asteroids that pose the greatest risk to our planet.

• Size: The size of an asteroid is one of the most important factors in determining its potential threat to Earth. Larger asteroids have a greater potential to cause damage if they impact our planet. The Didy List prioritizes asteroids that are larger than 140 meters in diameter.
• Velocity: The velocity of an asteroid is another important factor in determining its potential threat to Earth. Asteroids that are traveling at high speeds have a greater potential to cause damage if they impact our planet. The Didy List prioritizes asteroids that are traveling at speeds greater than 5 kilometers per second.
• Distance from Earth: The distance of an asteroid from Earth is also an important factor in determining its potential threat to our planet. Asteroids that are closer to Earth have a greater potential to impact our planet. The Didy List prioritizes asteroids that are within 0.5 astronomical units of Earth.
• Other factors: In addition to size, velocity, and distance from Earth, there are a number of other factors that can affect an asteroid's potential threat to our planet. These factors include the asteroid's composition, shape, and rotation. The Didy List takes all of these factors into account when prioritizing asteroids.

Regularly updated

The Didy List is a dynamic and ever-changing document. As new asteroids are discovered and characterized, they are added to the list. This is important because it ensures that the list remains current and accurate, and that astronomers and planetary defense experts have the most up-to-date information on potential threats to Earth.

• New discoveries: New asteroids are discovered all the time. In 2021, astronomers discovered over 3,000 new asteroids. These new discoveries are added to the Didy List as they are characterized.
• Improved characterization: As astronomers learn more about asteroids, they can better characterize their size, shape, and composition. This information is added to the Didy List and helps astronomers to assess the potential threat posed by each asteroid.
• Changing priorities: As new asteroids are discovered and characterized, the priorities for planetary defense may change. The Didy List is updated to reflect these changing priorities.
• International collaboration: The Didy List is maintained by the International Astronomical Union (IAU), which is a global organization of astronomers. This ensures that the list is updated regularly with the most up-to-date information from astronomers around the world.

International collaboration

The International Astronomical Union (IAU) is a global organization of astronomers that was founded in 1919. The IAU is responsible for maintaining the Didy List, which is a prioritized list of asteroids that are considered to be the most significant threats to Earth. The IAU's involvement in the Didy List is essential because it ensures that the list is updated regularly with the most up-to-date information from astronomers around the world. This international collaboration is critical for planetary defense, as it helps to ensure that we are prepared for any potential asteroid impacts.

The IAU's work on the Didy List is just one example of the importance of international collaboration in planetary defense. Astronomers from all over the world work together to track asteroids and comets, and to develop technologies to deflect them if necessary. This collaboration is essential for protecting our planet from the threat of asteroid impacts.

In addition to the IAU, there are a number of other international organizations that are involved in planetary defense. These organizations include the United Nations Office for Outer Space Affairs (UNOOSA), the European Space Agency (ESA), and the National Aeronautics and Space Administration (NASA). These organizations work together to coordinate planetary defense efforts and to develop new technologies to protect our planet from asteroid impacts.
