Objects in space headed towards Earth

NASA’s Center for Near Earth Object Studies tracks large objects, such as asteroids, that have passed Earth or are headed towards it. Reuters visualized the nearest objects in the database.

The graphic starts at Earth’s surface, and you get farther away as you scroll down. Speed is plotted on the horizontal, symbols are scaled by the object’s minimum diameter, and yellow indicates objects on the way.

Illustrations after the initial graphic do a good job of providing scale for if any of these objects hit us.

Asteroid simulator for before the big one hits

Knowing the impact of an asteroid falling in your city might not seem immediately relevant, but if there’s one headed toward Earth and NASA is unable to knock it off course with one of their rockets, you will definitely want to know what will happen and prepare accordingly.

Good thing Neal Agarwal, based on research from Gareth Collins and Clemens Rumpf, made an asteroid simulator. Set the material, size, speed, impact angle, and location, and see the effects from the resulting crater, fireball, shock wave, wind, and earthquake.

Asteroid database

600k asteroids

Asterank is an asteroid database maintained by Ian Webster, an engineer at Google. It contains information for over 600,000 asteroids.

Scientists know very little about the composition of asteroids. Most data used in our calculations come from the JPL's Small Body Database and the Minor Planet Center. The overwhelming majority of asteroids have no spectral classification and are missing other important data attributes. Without full information it is impossible to fully estimate the true value of an asteroid or the cost of mining it.

Asterank applies accurate, up-to-date information from world markets and scientific papers. To ensure realistic estimates, data from meteorities on Earth and known reference asteroids heavily influence our calculations.
