It seems that Mars will be "buzzed" this weekend by a comet the size of a small mountain. :-O

Once-in-a-million-year comet, that part is nice.

Thanks Wiggo.

Here's what NASA has to say about this event.

Does anyone know whether this Mars flyby will change the trajectory of the comet?

NASA charts do not show any change in the comet's path.

I wonder how intense the tail of this comet will become as it plunges deeper into the solar system. It is believed to be a first time visitor to the inner solar system so I guess no one knows for sure.

The Mars Orbiters should give us more data on the tail. It seems they have survived. There was once (I believe 1910) a scare because the Earth would be within the tail of Halley's comet. People were frightened by an article by Camille Flammarion. In Florence, people prepared for the event by planning to spend the night of the comet's passage with food and Chianti wine available. Astronomer Paolo Maffei gives a vivid account of that night in his book "La Cometa di Halley". Nothing evil happened, except for some hangovers.

Now that the comet is past Mars where is it heading? Will it develop a tail that will be visible from earth. It looks like all the scientific community was interested in was the flyby as I can't find any info about it's future path.

Thanks Gary, I looked. There is a lot of raw data there but I couldn't find any discussion or graphics related to Siding Springs.
