Simulated Gliese 581 mission

[zaarin]

In the last couple of years we have discovered a planet orbiting the star Gliese 581. This planet is believed to be the appropriate distance from its parent star for water to be liquid on the surface and therefore may be able to support life. The planet has been designated Gliese 581g.

I have noticed that Donatello has already done some work on artistically impressioning some of the worlds within the Gliese star system.

As an avid fan of orbiter, and reading through previous posts I know what most of you are going to tell me

"Orbiter cannot process interstellar flight"

I say codswallop!

Gliese 581 is 20.3 lightyears away or only 1283772 AU away from us. Why can't you plonk an object that distance away from SOL?

I honestly believe that sending a probe to this world deserves some study irrespective of whether or not we have or will ever have the technology to go there.

One of the first aspects of this challenge will be to re-code the orbiter core to take into account the gravity of other stars.
Can orbiter comprehend large values of AU distance?
One simple solution I had in mind was to treat SOL as a planet, treat the massive black hole in the center of the galaxy Sagittarius A as the sun, treat SOL as a planet and Earth as a moon of that planet and Gliese as another planet orbiting Sagittarius. (can orbiter do moons of moons?)

Possibly chuck in a few other stars just to make it interesting.

Then you have to design a hypothetical anti-matter based fuel starship that can do 0.9c or 9/10ths the speed of light.

The purpose of this is to work out how a starships curved tradjectory would behave over such a vast distance.

I am willing to help with such a project, I know this is an ambitious one and my first, but if you guys can give me some pointers and some advice I would be very greatful.

And please don't reply with "It's impossible it can't be done"

Advice: start reading on IEEE floating point formats. Hint: Orbiter core engine uses meter as a unit of distance.

You can always use my version if you want to....

Thank you both for your replies...
Wishbone: 1 AU is 149,597,870.7km or 149,597,870,700m x 1283772 AU

=

192,049,557,664,280,400m which is the distance from here to Gliese in meters.

Can IEEE floating point numbers comprehend this?
If not, would the entire orbiter core have to be re-written with 64-bit or 128-bit distance values instead?

Also if you put Sagittarius A*'s distance into the system, that's 9461000000000000 (m in light year) x 26,000 (approximated distance, Sag A* is +-1400ly off that) which = 245,986,000,000,000,000,000m from SOL.

Can we simulate Gliese and SOL's orbit around Sag A* based on the fact that Gliese is moving away from us at:

Proper motion (μ) RA: −1233.51[3] mas/yr
Dec.: −94.52[3] mas/yr

?

Also

fsci123.... Have you already made one of these?

I know someone has made a Gliese 581 star system and people have re-textured and modified it as time goes on. But have you actually got a mod that can simulate long-distance inter-stellar flight without "warp drive" which is impossible?

I do however believe that relatavistic travel IS possible and maybe in about a thousand years from now we might have a ship that can do just that. 0.9c and in two thousand years we'll have a ship that can do 0.95c. That's what I think anyway.

i am making a simaler project called sorpendarin. it even will have other galaxys!


but it wont be done for another 10 or so years. Edit: never mind,that was off topic and i think it was a necropost:facepalm:
