Homework Help: Astronomy NEOs

Posted by Lewis on Thursday, February 7, 2008 at 6:37am.

When Stuart ( 2003) revised the magnitude for spotting NEOs comets, over 1KM etc from H =18 to H 17.75 ... did this increase , decrease, or did the population of NEOs stay the same.

and why ???

Me personally ..I think the number of NEOs over 1 KM has decreased ..as it is now easier to spot the larger NEOs with the revised magnitude calibration.....

But would appreciate input from others :-)

Cheers

The abundance or population of Near Earth Objects in the solar system, that are greater than 1 km in size, is independent of our ability to see them. (The change from 18 to 17.75 for the detection threshold visual magnitude will make then harder to see).
