NASA launches website with all near-Earth asteroids

NASA has unveiled a website for a next-generation monitoring system for Earth-threatening asteroids. It is already available online.

The new monitoring technology is called Sentry-II. It replaces Sentry, which was deployed in 2002. NASA has since developed a new algorithm, which will more accurately estimate the risk of asteroid collision with Earth.

The point is that Sentry didn't take into account the Yarkovsky effect - a phenomenon in which an asteroid gets a weak, reactive boost from thermal radiation from a surface that is heated during the day and cools at night. Sentry-II solves this problem. The Jarkowski effect affects the orbit of an asteroid for a long time. For example, it shifts the orbit of Apophis, which has a chance of colliding with Earth in 2068.

The "Eyes on Asteroids" website can already be visited and all the asteroids detected can be studied there. NASA will be updating the data continuously.
