Let’s be careful out there!

Here’s a fun video to consider, via Spaceweather.com.  It shows the map of the solar system updating from 1980 to present as more asteroids are discovered.  

As Spaceweather notes

Warning: Feelings of claustrophobia have been reported among some viewers. It’s crowded out there!

New discoveries appear in white.  Final colour indicates how close the asteroid comes to the inner solar system – Earth crossers in red, Earth approachers (perihelion less than 1.3AU) in yellow, and all others in green.  Orbital elements from database created by Ted Bowell and associates.  And there’s an up-to-date Near Earth Objects map at the Armagh Observatory website.  Credit: Scott Manley.

Remember, Jupiter is usually our friend and lord…  [Adds – I’ve used a clearer final link]

    “here’s a fun video”

    are you mad Pete… that video should be shown after the watershed, anyone not worried after watching that video has lost the will to live.

    and good stuff yet again Pete

    I don’t remember hearing a good explanation as to why the asteroids didn’t coalesce into a planet. Jupiter?

    Interesting article in the Telegraph about meteor showers and the dinosaurs:

    The ability to sort out galactic problems like this would be a true test of whether or not we are masters of our own destiny.

    Thank god we have Bruce Willis to sort all this out

    “are you mad Pete…”

    Possibly, Oracle, possibly…

    Could be.

    Plus they’re not static.

    And, despite the number, their combined mass is relatively low [compared to a planet] and they probably lack sufficient gravity to coalesce into a single body.
