Fraid not as large masses attract small masses. Therefore as long as there is a large mass in system there will be an orbit of an angular velocity proportional to the mass of the star around the centre of mass in the system.

No my point is that if 1G is all The Earth exerts, do you need to calculate the effect of it ? most of the time probably not.

How many G does a star exert ?

Well, The star example is a simple example, Seeing as the planets are supposed to move I guess the noticeable examples would be everything in system as everything with mass is being affected by gravity.



Everything with a mass exerts gravitation force, it is just negligible for those with a mass in tons much less than a moon and not a great deal for a moon either as demonstrated in video footage from 1969.


Although Titan (A moon of Saturn I think it is) is apparently not far off the mass of Earth.

It is far off.
(yada-yada*10^24 for Earth to yada-yada 10^23 kg for Titan.
Also note that the density of Earth is 2,7 times higher than that of Titan.

So maybe 0.25G but that is also going to depend on how close you are to it. Earth has 0.25G at a certain distance from the surface. I haven't looked into moon or planetary interaction so I don't know what a ship needs to do when it gets there. According to this Gravity the sun only exerts 26G

Maybe distance actually means distance from minimum safe distance.

Bob has taken all the gravity and used it to create pockets of near reality space accessible by wormholes. Come visit; cheaper than Disneyland Paris, and far more exciting.

Planets did rotate on their axis in the past. However, as apparently it made the Dust514 players a bit dizzy caused by the ludicrous speeds the planets rotated at, said planets were ordered to stop spinning.

A 24 hour rotation isn't going to be visible except in time lapse. A few planets in our solar system rotate at 3 times that speed. Errm yeah wonder if that makes a difference ?

I really must go out in a ship and have a look. So..

On the info tab I have Orbital Radius, Surface Gravity, Escape Velocity, Density and Mass going on here

Warp seems to stop 5000 km away from this moon, so it might be a little while for me to edit this with the result.

3000 km and closing

2500m/s I calculate that as about 10 minutes

Ok here, the moon kind of disappears as the 3D camera struggles to view your ship and the moon at the same time. Hmm and as you seem to move through the inside of the moon. Position myself so the moon is directly between me and the planet and ... Warps straight through stopping 16000km from the planet.

OK so when I'm really bored I will try flving into the middle of a planet.

EVE's space physics is probably easiest to compare to "tennis balls in water" (non-rigid balls in non-viscous fluid). It's of course not accurate or realistic but it the gaming experience is better since that's what most people find easiest to understand and adapt to. There is no gravity and the planets and moons are stationary.


Ooh, if only they weren't.

If only stations would orbit their planet / moon they are on.
Same with a POS or any other celestial.

It would make EVE fun...warp to your bookmark, just to see your POS 149km away...

You must be new here.

Let me explain.

All objects with mass attract every other object that has mass with a force that scales with the product (Read: The mass of one object multiplied by the other object's mass) of the two masses involved.

This force is only reduced by distance and not negated completely. Therefore everything in the system has to orbit the star to maintain its distance from said star, if you was close to the star, the time taken to circle the star would be very noticeable but due to EvE physics it does not, that is what I was referring to.

Yes because 1G is a fairly big bit of acceleration. (about 10 meters per second per second)

And well, I don't know, depends on the mass of the star and your distance from it. Look up Newton's law of universal gravitation

EVE isn't real?!?
Can I get a cash refund and the use of a time machine to take me back to the start of 2010 please?
I'll even contract over my assets before I climb inside a time travelling machine which is larger on the inside than the outside.

Physics sucks!!! Lolxxx

It's sitting on my DVD shelf right next to "Captain America: the Winter Soldier". I have to admit, it's a rather thrilling survival ride, and it was awesome on IMAX...twice.

Let's discuss overhauling the way we get intel in EvE.

I just remember it as an energy field created by all living things - it surrounds us and penetrates us. It binds the galaxy together.

I believe I did mention distance.
t's only a fair bit of acceleration if you are close enough for it to have that effect, which if the closest you can warp to the example I just tried is 16000km, then you are going to have to align to the planet on micro warp drive for a few hours before that gravitational effect that CCP has ignored would be noticeable.
