Astronomical Society of Victoria vice president Perry Vlahos said Victorians could have caught a glimpse of something out of this world tonight.

"The first thing I thought was it was space junket and it did turn out to be space junk," Mr Vlahos said.

At about 6pm, Advertiser readers were quick to notice what many thought was a meteor crossing the sky.

"Meteors are all over and done with in a second or two," Mr Vlahos said.

"This was much longer lasting and it took a while to disintegrate."

By contrast, comets move incredibly slowly.

"If you ever do look at a comet, you won't even be able to notice it is moving, it is that slow," Mr Vlahos said.

A rocket launch in Russia at about 5.30pm AEDT on Friday night could be the reason for the space junk, according to Mr Vlahos.

"This sort of thing happens three times a year, if you are looking at the right time, in the right direction and its a clear sky," he said.

Thanks to all of our readers who took the time to send in photographs and videos to the Bendigo Advertiser Facebook page of Friday night's space event.
