Just how far away is Saturn?

Just had a rough tinker with some numbers.... Give or take the odd month, or maybe even a year but...

I reckon, it would take a bullet fired from a High Velocity rifle (travelling at a velocity of 6500 fps) 21 years to reach the rings.

I'm doing this so I can try and get some sort of scale into things, as now everyone who knows me, knows I'm into Astronomy they keep asking me how far away things are!

If anyone has any other methods let me know!!!

You kind of have to take into account which side of the Sun we are on, as well as where the planet is. Mars is close now, being barely past opposition, while Saturn can be another 150 million kilometers away at inferior conjunction. (Of course, you can't see it then, but just for illustration.) I generally use a "fudge factor" of 80 million Km, depending.

That's a great chart there, SkyGuy, very helpful! 8)

I will do that just give me a couple of days a s i am run off my feet just now
