Well, get used to it because 2013 actually *is* going to be unusually active from an astronomical perspective, enough so that I got my niece a decent lower end telescope for Christmas.
There’s one more known near-Earth asteroid, then comet PANSTARRS in March, followed by the green comet Lemmon already visible in the southern hemisphere that will be visible to us in April, and then there’s the big one, comet ISON, that appears poised to be the second brightest object in the sky for a month or so, behind only to the sun, visible in broad daylight.
It will be at it’s brightest after it passes perihelion in late November, assuming it doesn’t break up from passing fairly close to the sun as comets go.
I am really looking forward to seeing comet ISON and am really hoping it doesnt break up or fizzle out. Of course I'm also hoping that it doesnt bring out the dooms day cult nuts and if it does, at best they are only mildly disappointed when the World doesnt come to an end or that they only off themselves and not anyone else.
And kudos to you for getting your niece a telescope for Christmas. If only I had had a really cool uncle like you : )
