I spend a lot of time looking at the stars at night and finding the constellations. Well, last week, before it got all hot and muggy, the sky was exceptionally clear, so I took the opportunity to stargaze.
I was sitting in a lawn chair with my binoculars, smoking a cigarette and looking at an extremely magnificent Jupiter chilling out in the southern sky. (Hey, it was like magnitude -2. Freakin' blinding, dude.) Then I looked up and found Hercules, and then I went for the little dipper, but it was too far northwest, and my house was blocking my view, much to my chagrin.
And then I started thinking about the SF novel I'm writing, which takes place on Mars.
And the question popped into my head: Would Mars have the same constellations as Earth?
My first thought was "no." It's a different planet, so a different view it is. But then I thought, "Well, cosmically speaking, Mars isn't that far away at all."
I'm sure there's some kind of mathematical equation to figuring this out, but math is my fallacy. So now I'm asking you.
Yes or no. Why or why not.
I'm curious. 3nodding

I don't know much about astronomy, but I would think the constalations wouldn't be too different because like you said, Mars and Earth aren't that far apart.
Just wait till Vioja get's here, he's the Astro expert.
whee
YOu went stargrazing with Binoculars!
I've never tried that...
*looks for binoculars*
I have looked at the moon once before with binoculars.

Binoculars come in handy when you need to look at the stars that have higher magnitudes. cool It's amazing how a seemingly dull area in the sky will brighten up with a little pair of binoculars. :3

That's neat.
I should try it sometime.
heart
How far are ya on the SF Novel your wrighting.
You should post an excerpt or something in the literature subforum.
I'd love to read it sometime.

The constellations would be virtually identical. Consider the fact that the Earth orbits the sun in a wide circular orbit. The constellations are not appreciably different in summer than they are in winter. Mars is on the next orbital track out but the distance between Earth and Mars varies hugely due to their different orbit times.
The distance between the Earth's summer position and it's winter position is very small in astronomical terms, too small to create a different view of the universe. The same applies between Earth and Mars. In fact, I doubt whether there would be any noticeable difference in the night sky as seen from Pluto.

The constelations would be the same, for the reasons mentioned above, but their position in the sky would depend on the orientatin of Mars' rotational axis. They would still have fixed positions relative to eachother, but different in relation to the horizon. I am not sure what angle Mars is inclined at relative to Earth though.

I THINK that many of the constilations between Mars and Earth veiws of the sky would be simmilar if not the same save a slight change in their path and position in the sky. you may want to read up on the Mars rover and see if it took any pictures of the sky.

I say the stars are the same of course. The constellations may be a little different because the view is also a little different.

Your question is not a wrong one.
As i want to answer,here you go,
the constellation will definetly be the same. wink
Because as you said that planet is not much far from us and you don't need an mathematical equation for that. 3nodding
When we compare our planet and neighbours to the whole constellation,we are just sooo small and we are obviously are part of that whee .
