Very impressive to see 30 years compressed.

View of the solar system showing the locations of all the asteroids starting in 1980, as asteroids are discovered they are added to the map and highlighted white so you can pick out the new ones.
The final colour of an asteroids indicates how closely it comes to the inner solar system.
Earth Crossers are Red
Earth Approachers (Perihelion less than 1.3AU) are Yellow
All Others are Green

Notice now the pattern of discovery follows the Earth around its orbit, most discoveries are made in the region directly opposite the Sun. You'll also notice some clusters of discoveries on the line between Earth and Jupiter, these are the result of surveys looking for Jovian moons. Similar clusters of discoveries can be tied to the other outer planets, but those are not visible in this video.

As the video moves into the mid 1990's we see much higher discovery rates as automated sky scanning systems come online. Most of the surveys are imaging the sky directly opposite the sun and you'll see a region of high discovery rates aligned in this manner.

At the beginning of 2010 a new discovery pattern becomes evident, with discovery zones in a line perpendicular to the Sun-Earth vector. These new observations are the result of the WISE (Widefield Infrared Survey Explorer) which is a space mission that's tasked with imaging the entire sky in infrared wavelengths.

Currently we have observed over half a million minor planets, and the discovery rates snow no sign that we're running out of undiscovered objects.

Orbital elements were taken from the 'astorb.dat' data created by Ted Bowell and associates at http://www.naic.edu/~nolan/astorb.html

Curious that there is the asteroid belt, which is of course thick with objects, but the orbit of Mars and Venus are clearly both in a relatively sparse zone, it seems as though we are in the proverbial thick of things. I wonder if this is real or only represents the biased results from an area of focus by the research (since these things could clearly result in us having A Bad Day).
 
I found this on youtube that gives a very visual representation of asteroids in the inner solar system: http://www.youtube.com/watch?v=S_d-gs0WoUw

It is well made and underlines very much the realness of asteroids and that we are not alone, as the latest Dot Connector magazine highlights in several articles. Notice how the counter moves slowly in the beginning and how in the end it is teeming with discoveries. :O

The person who put it up has this to say:

The scale of the video at 1080P resolution is roughly 1million kilometers per pixel, and each second of video corresponds to 60 days.

For those new to the forum then there is a good article by Laura which makes a good list of meteorites and asteroids impacting the earth or just close calls: Meteorites, Asteroids, and Comets: Damages, Disasters, Injuries, Deaths, and Very Close Calls

Another article also by Laura is Tunguska, Psychopathy and the Sixth Extinction

The two threads have been merged.
 
Geez...it's getting really crowd out there, and imagine the dark star will be coming through that shortly.

Something wicked this way comes, indeed...
 
I just discovered that video. Like the Celts may have answered to Alexander the great : what we should only fear is that "the sky falls on our head"

Amazing :cry: However the 2D representation is a bit misleading.

There is a tour in 3D with that one :

Wow... sure looks like 'The Ring" or Walkner's "Das Ring"
or Tolkien's cursed ring.... :/

Unfortunately, I could not get captions so my interpretation
might be a bit off :P
