Visualization of asteroids discovered in the last 30 years
Astronomer Ted Bowell of the Lowell Observatory and his colleagues used the astorb.dat dataset (The Asteroid Orbital Elements Database), which contains information about all the asteroids known to mankind, created a computer model of our solar system visualization of all nearby asteroids.
This truly impressive work has become available for viewing to everyone. ')
At the very beginning, the animation shows the locations of all asteroids known at the beginning of 1980, then, in chronological order as they are discovered, new asteroids are added to the image. This animation is a vivid and illustrative example of the development of modern astronomy and the history of the study of the solar system and uses data from observatories and amateur astronomers from around the world. The animation shows our Sun and the orbits of the 5 planets closest to the star. You can see how in 2010 the search for new asteroids was greatly accelerated, all this is the merit of the new NASA telescope - WISE , which was launched just this year.
White color indicates asteroids discovered at a certain point in time. Red - asteroids crossing the orbit of the earth. Yellow - asteroids passing near the Earth. Green - safe for us asteroids.
I advise you to watch a video of at least 720p
At the beginning of 1980 , just under 9,000 asteroids were known. Currently, the number of known asteroids has exceeded 500,000 and is rapidly creeping up.
