Light pollution is real, and it’s a real problem for both professional astronomers, and us amateur star gazers with backyard telescopes. Thus, with this known we ought to all realize that our astronomers may not be able to see an asteroid headed for Earth as easy as one might think. Remember we have things blocking our direct line of sight, such as the Moon, other planets, and our Sun, so we cannot see the entire system all of the time.
In fact, in an interesting article in SpaceWeather Online entitled; “Orionid Meteor Shower – 2010″ it stated that the “Earth is passing through a stream of debris from Halley’s Comet, and this is causing the annual Orionid meteor shower. Bright moonlight is reducing the number of visible meteors; nevertheless, sky watchers are reporting some bright Orionids. The best time to look is during the hours before local dawn on Thursday, Oct. 21st, and again on Friday, Oct. 22nd.
Now then, just as us backyard astronomers have challenges seeing all that is, our professional astronomers can also be challenged at times, remember it’s a very big sky with 100s of trillions of Earth sized areas to scan for a potential asteroid threat. These NEOs (Near Earth Objects), ECAs (Earth Crossing Asteroids), and Comets are not always so easy to detect.
Nevertheless, if you do find one which has not been found before, as I understand it, you get to name it! So, maybe this might be an interesting hobby for you, but rest assured, it’s not that easy. Please consider all this.
